•  Audi A3 Sedan, 2014

The Exterior design
The Audi A3 Sedan has a sporty stance on the road, and it is precise and highly expressive in every detail. Its design is a cross between the classic three-box concept and the coupé philosophy. The "tornado line" design element forms a distinct light-refracting edge that runs over the entire side. The overhangs are short. The four-door car has a 2.64 meter (8.66 ft) long wheelbase and an overall length of 4.46 meters (14.63 ft).

Above the side sills, the dynamic line rises more sharply than on the other two A3 models. The side surfaces are more intensively curved, and the wheel arches are slightly more flared. With a width of 1.80 meters (5.91 ft), the A3 Sedan is eleven mm (0.43 in) wider than the A3 Sportback; its height (1.42 meters [4.66 ft]) is still nine mm (0.35 in) lower than that of the Sportback.

The 4-door car also expresses independent lines in the contour of its hood, in the bumpers, air intakes and its implementation of the singleframe grille. At the rear, the spoiler is integrated in the trunk lid, and the lights emphasize the car's horizontal lines with their broad and low cuts. LED technology is available as an option. Audi will also be offering full-LED headlights right at market launch - their innovative technology and distinctive appearance underscore the exceptional positioning of the Audi A3 Sedan.

Body
With a 1.4 TFSI engine, the sedan has a curb weight of just 1,250 kg (2,755.78 lb). Audi uses many hot-shaped steel parts in the passenger compartment for low weight and maximum strength, while the engine hood is made of aluminum. The body is very rigid, crash-safe and quiet.

The strict dictate of lightweight design carries over into the interior and the engines as well. The four-cylinder engine weighs just over 100 kg (220.46 lb).

Powertrain
When the Audi A3 Sedan launches in Germany and Europe, the engine line-up will consist of three four-cylinder engines. Completely redesigned, the engines bring together efficiency technologies from Audi - direct fuel injection, turbocharging, innovative thermal management and the start-stop-system. The line-up of engines and transmissions will grow further, and will include two new basic engines.

The 2.0 TDI produces 110 kW (150 hp) and develops 320 Nm (236.02 lb-ft) of torque. It accelerates the Audi A3 Sedan from 0 to 100 km/h (62.14 mph) in 8.7 seconds and takes it to a top speed of 220 km/h (136.70 mph). Its combined fuel consumption is 4.1 liters per 100 km (57.37 US mpg) - for a CO2 equivalent of 108 grams per km (172.20 g/mile).

Key performance parameters of the 1.4 TFSI are 103 kW (140 hp) and 250 Nm (184.39 lb-ft). At low engine load, the COD (cylinder on demand) system deactivates two cylinders. The 1.4-liter engine gives the car a combined fuel consumption of just 4.7 liters fuel per 100 km (50.05 US mpg); its CO2 emissions are 109 grams per km (175.42 g/mile). It takes just 8.4 seconds to accelerate from 0 to 100 km/h (62.14 mph), and the car's top speed with this engine is 213 km/h (132.35 mph).

The 1.8 TFSI produces 132 kW (180 hp) and 250 Nm (184.39 lb-ft) of torque. It utilizes an extensive package of high-end technologies, including dual injection into the combustion chambers and the induction manifold. It enables sporty performance, taking 7.3 seconds for the standard sprint to 100 km/h (62.14 mph) and reaching a top speed of 235 km/h (146.02 mph). Its combined fuel consumption is 5.6 liters per 100 km (42.00 US mpg), equivalent to 129 grams CO2 per km (207.61 g/mile).

Chassis
The pole position that the Audi A3 Sedan has enjoyed in its segment is largely due to its chassis engineering. Providing the foundation here is a finely balanced axle load distribution (60 percent front and 40 percent rear, varies somewhat for different engines). All engines are tilted twelve degrees towards the rear, while the front wheel suspensions are placed far forward.

The front suspension is a MacPherson design with A-arms and aluminum pivot bearings. It is joined to an aluminum subframe. The electromechanically assisted steering system operates sensitively and efficiently together with various assistance systems. In the four-link rear suspension, which utilizes a steel crossmember, the springs and shock absorbers are mounted separately. The sport suspensions for the Ambition line and S line lower the body by up to 25 mm (0.98 in).

The Audi A3 Sedan has 16- to 18-inch-wheels; quattro GmbH can also deliver wheels up to 19 inches in diameter. The front brake discs are internally ventilated.

Electronic stabilization control or ESC also includes an electronic differential lock. In fast driving through curves, it brakes the inside front wheel very slightly to minimize understeering and improve traction.

Interior
The interior of the Audi A3 Sedan is characterized by impressive attention to detail. The lines and surfaces are cleanly designed, and a long arc spans the width of the windshield. The instrument panel with its curved front is slender, and the center console is slightly turned towards the driver. The optional color display of the driver information system (DIS) shows images in highly detailed 3D graphics.

Starting with the MMI Radio system, the MMI operating system has an electrically extending screen. Its terminal is housed in the console of the center tunnel. The electromechanical parking brake is activated by a pushbutton. The steering wheel has either three or four spokes, depending on the version. The customer can also order the steering wheel with a flat bottom, multifunction keys and shift paddles. Audi can also install sport seats in the front as an option. They are standard in the Ambition line, where S sport seats with integrated head restraints are available as an option.

The interior colors - black, titan gray, pashmina beige and chestnut brown - are based on the specific equipment line. The two-tone Audi design selection lasso brown creates an exclusive color world. The S line sport package, which can be ordered for the A3 Sedan Ambition, immerses the interior space entirely in black. Available upholstery materials include fabric covers, a mix of fabric and artificial leather, Milano leather and a combination of Pearl nappa leather and Alcantara.

Thanks to the long wheelbase, rear passengers also enjoy ample space and comfortable entry. The cargo capacity of the trunk measures 425 liters (15.01 cubic feet). This capacity can be increased by folding down the rear seatbacks which come with a load-through hatch as an option. The trunk lid automatically swings upward after it is unlocked.

Infotainment and Audi connect
Like its siblings in the model series, the Audi A3 Sedan makes use of the new modular infotainment system (MIB). The top system is MMI Navigation plus with an SSD hard drive offering 64 GB of storage, a DVD drive and whole-word voice control. A high-resolution 7-inch-screen shows the map image in detailed 3D graphics. The MMI Navigation plus system interfaces to cell phones and mobile players via Bluetooth. The user terminal has a turn/push control designed as a "touchwheel" with MMI touch - the touchwheel's top surface is a touch-sensitive pad for inputting letters, symbols and numbers.

Other infotainment components include a module for digital radio reception (DAB+), the Audi phone box for conveniently coupling a cell phone to the car antenna and the Bang & Olufsen sound system. Its 705 watt amplifier drives 14 loudspeakers in 5.1 surround sound, and LED light guides illuminate the woofer grilles in the front doors.

Audi connect covers all technologies that network the driver with the car, the Internet, infrastructure and other vehicles. Audi has made the system even more appealing - whenever possible the connection to the Internet is run over the super-fast LTE standard. The LTE telephone module replaces the previous UMTS module here, which enables a download rate of up to 100 MBit/s in the car.

Audi connect lets passengers conveniently surf and e-mail via an integrated WLAN hotspot. For the driver, it brings customized Internet services from Audi into the car. They range from navigation using images from Google Earth and Google Street View to Audi traffic information online and the smartphone app Audi music stream. News and information services complete the line-up. The online community services Facebook and Twitter are integrated in a vehicle-friendly way; along with a text-to-speech function, a practical text function is provided with prepared text units.

A new Audi connect service that is making its debut in the A3 Sedan is parking space information. It shows information on parking spaces, parking garages and underground garages near a destination selected by the driver. Whenever possible, the service indicates the number of available spaces and parking fees. The street address of the parking space can be used as a navigation destination.

Features
The new Audi A3 Sedan is launching with a generous set of standard features. The package of restraint systems includes a knee airbag for the driver. The DIS with color display in the Ambition and Ambiente lines includes an efficiency program, gearshift indicator and rest recommendation feature.

In addition, the Ambition line has a sport suspension, 17-inch-alloy wheels, sport seats and the Audi drive select system. The Ambiente line adds a cruise control system, interior LED lighting package and rear parking assistant. In addition to these standard features, Audi also offers other individual comfort and convenience options - such as a panoramic glass sunroof, convenience key, auxiliary heating and xenon-based adaptive lights. In conjunction with MMI Navigation plus, the lighting system utilizes route data to optimally illuminate the roadway depending on the driving situation.

The driver assistance systems also come from the premium class. The adaptive cruise control (ACC) maintains a desired distance between the A3 Sedan and the vehicle in front of it up to a speed of 150 km/h (93.21 mph); with the assistance package, which combines multiple systems, the control range is extended up to 200 km/h (124.27 mph). When combined with S tronic, ACC also offers a stop&go function for low speeds.

The rear radar sensor Audi side assist monitors lane changes, while Audi active lane assist helps the driver to keep within the lane by making slight corrections to the electromechanical steering as necessary. The video camera of Audi active lane assist is also used for traffic sign recognition. A high-end solution for convenient parking is park assist with display of the surroundings - it relieves the driver of steering work in parallel and perpendicular parking maneuvers.

Audi A3 Cabriolet, 2014

 

 

 

•  Audi A3 Cabriolet, 2014

Sporty, elegant and multi-faceted - Audi presents the new A3 Cabriolet. The compact four-seater impresses at first glance with its flowing lines and soft top. It is also at the top of its class technically - with systematic lightweight design, new engines, multi-faceted networking and high-performance assistance systems.

The Exterior design
The new Audi A3 Cabriolet has grown compared to the previous model: its length increased from 4.24 to 4.42 meters (13.91 to 14.50 ft), its wheelbase from 2.58 to 2.60 meters (8.46 to 8.53 ft) and its width from 1.77 to 1.79 meters (5.81 to 5.87 ft). Only its height (1.41 meters [4.63 ft]) was reduced by 15 millimeters (0.59 in). This gives the four-seat convertible a more elegant and sporty look on the road. Luggage capacity grew by 60 liters (2.12 cubic ft), and it is easier to load. The wheel housings can handle wheels up to 19 inches in size.

The front of the Audi A3 Cabriolet is characterized by the Singleframe radiator grille. The flat headlights give it a resolute look; they emphasize the horizontal styling and the air intakes in the bumper. Audi offers headlights with LED technology as an option; they are the only LED headlights in the compact segment to offer variable headlight leveling control.

The rear overhang plays a key role in the harmonious proportions of the two-door car. The windshield frame is made of aluminum - and an aluminum-look trim strip runs around the entire car. On the flanks, the design features a taut tornado line and contoured sheet metal surfaces that create a fascinating interplay of light and shadow.

The soft top
The new A3 Cabriolet has a soft cloth top that is stretched over a lightweight kinematic mechanism made of magnesium-steel, and it complements the car's design perfectly. At the press of a button, the top opens or closes electro-hydraulically in less than 18 seconds, even while driving up to 50 km/h (31.07 mph). In the opened state, the top - folded into three layers - rests in a tray that barely affects luggage capacity, which is 287 liters (10.14 cubic ft).

The fully automatic soft top has a glass rear window and is offered in Black as standard. A fully automatic acoustic top is available as an alternative; it has a thicker inner foam layer which reduces the already low interior noise level of the Audi A3 Cabriolet even more. The acoustic top is available in the three exterior colors of Black, Gray and Brown, and its roofliner is available in black and lunar silver. A wind deflector is standard for the Ambiente trim line, and head-level heating is an option for the front seats. An active rollover protection system protects the occupants in case of a rollover accident. It consists of two spring-loaded plates that are recessed into the body.

Body
In the base version, the car's curb weight is just 1,365 kilograms (3009.31 lb) - the new Audi A3 Cabriolet is around 50 kilograms (110.23 lb) lighter than the previous model despite its larger size and better comfort. Including its special reinforcements, which deliver high torsional stiffness, the body-in-white weighs 30 kilograms (66.14 lb) less than previously; the engine hood is made of aluminum. Weight was also significantly reduced in the interior and in the engines. This let Audi - a pioneer in this technical field - set an impressive best value in the compact class. Customers can choose from 16 different exterior paints for the body.

Interior
Elegantly drawn lines and clean surfaces also typify the interior design of the new Audi A3 Cabriolet. The instrument panel is lean and low, its front is slightly curved, and the center console is angled slightly towards the driver. The large, round air vents in jet design, the control panel for the air conditioner and the three-dimensional trim strips bring premium class elegance into the interior. The optional lighting package includes a touch-sensitive switch for the reading lights - a feature being offered for the first time.

As in every Audi, workmanship quality is uncompromisingly high, and the car's controls are simple, intuitive and convenient. It offers enough space for four adults, and the seatbacks of the two rear seats can be folded down which opens up a wide through-load area. The steering wheel and seats are new designs, and the also new electro-mechanical parking brake is operated by a pushbutton on the center console.

The trim lines are named Attraction, Ambition and Ambiente. The S line sport package for the Ambition line immerses the interior space entirely in black. Customers can choose cloth, leather or Alcantara/leather upholstery materials. The Audi design selection lasso brown conveys an exclusive look.

Assistance systems
Driving in the new Audi A3 Cabriolet is even more impressive with its highly developed assistance systems. The driver information system with efficiency program and attention assist are already standard features on the Ambition and Ambiente lines. The options program includes adaptive cruise control, Audi side assist, Audi active lane assist, camera-based traffic sign recognition, park assist with selective display and various feature levels of the Audi pre sense safety system.

Also extremely attractive is the line-up of infotainment components; at the very top are the Bang & Olufsen sound system and MMI Navigation plus. The super-slender seven-inch monitor extends from the instrument panel electrically. The user terminal has a rotary/push button control that is designed as a touchwheel with MMI touch - the touchwheel's top surface is a touch-sensitive pad for inputting alpha and numeric characters.

The Audi connect concept aims to network the driver with his or her environment. In the new Audi A3 Cabriolet, this function - which supplements MMI Navigation plus - provides a connection to the Internet, and whenever possible via the fast LTE transmission standard. The integrated WLAN hotspot lets passengers use their mobile devices to surf and e-mail freely.

The system brings Internet services from Audi connect into the car for use by the driver - from navigation with Google Earth images and Google Street View to online traffic information and services such as Facebook and Twitter. The latest service from Audi connect is parking information; it shows available parking spaces in parking and underground garages and parking lots.

Drivetrain
The three newly developed engines being offered in the Audi A3 Cabriolet at its launch all emphasize the car's sporty character. The two TFSI engines produce 103 kW (140 hp) and 132 kW (180 hp) from 1.4 and 1.8 liters of engine displacement, respectively. The 2.0 TDI develops 110 kW (150 hp); Other engines will follow - ranging from the 1.6 TDI with 81 kW (110 hp) to the 2.0 TFSI, which will power the Audi S3 Cabriolet with 221 kW (300 hp). All engines in the new Audi A3 Cabriolet combine the technologies of direct injection, turbocharging and a start-stop-system.

On average, the three engines offered at market launch have twelve percent better fuel economy than the engines in the previous model - and they do so while improving driving performance. The 1.4 TFSI, for example, accelerates the new Audi A3 Cabriolet from 0 to 100 km/h (62.14 mph) in 9.1 seconds, yet its combined fuel consumption value is 5.0 liters fuel per 100 kilometers (47.04 US mpg) and its CO2 emissions are 114 g/km (183.47 g/mile). Also contributing to this efficiency is Audi cylinder on demand (COD) technology, which deactivates two of the engine's cylinders in low load conditions.

The new Audi A3 Cabriolet also features state-of-the-art technology in power transmission. At its launch, the 1.8 TFSI is being offered with a seven-speed S tronic; together with the Audi drive select vehicle dynamics system, it offers a free-wheeling function that further improves fuel economy. The 1.4 TFSI and 2.0 TDI are each paired with a manual six-speed transmission. This will be followed by the quattro all-wheel drive system - another new feature and USP of the compact Cabriolet.

Chassis
The chassis of the new Audi A3 Cabriolet impresses with sophisticated technology that delivers sporty handling, superior vehicle safety and a high level of comfort. Some of the components of the MacPherson front suspension are made of aluminum; the four-link rear suspension handles longitudinal and transverse forces separately. The power steering system features an efficient electromechanical drive.

The ESC stabilization control system integrates an electronic limited slip differential - this makes handling even smoother and safer at the vehicle's cornering limits while driving fast through curves. The brakes are powerful and durable. Wheel sizes range from 16 to 19 inches, and tire sizes range up to 235/35. Two versions of the sporty chassis are offered; the sport suspension lowers the body 15 millimeters (0.59 in), while the S line sport suspension is 25 millimeters (0.98 in) lower.

High-end options in the new Audi A3 Cabriolet include the Audi drive select vehicle dynamics system (standard on the Ambition line). The driver can use this system to modify engine management, power steering, S tronic and air conditioning operation over several modes. This control also extends to optional systems such as the adaptive suspension control system Audi magnetic ride, adaptive cruise control, adaptive light and progressive steering whose steering gear ratio becomes increasingly more direct when turning.

The new Audi A3 Cabriolet will come off the assembly line at Audi's plant in Gyor, Hungary, which Audi has expanded with an investment of more than 900 million euros. Sales begin this autumn in Germany, and first deliveries will be in the first quarter of 2014. The base price for the 1.4 TFSI (103 kW with cylinder on demand technology) is 31,700 euros. Many sporty and comfort/convenience options round out the standard features; they include the deluxe key and S sport seats with integrated head restraints and diamond topstitching in the shoulder area.

Audi S3 Cabriolet (preliminary data)
In the top S3 version, which will follow shortly after the car's initial launch, the compact Cabriolet delivers very sporty driving performance. The 2.0 TFSI engine produces 221 kW (300 hp) and transfers 380 Nm (280.27 lb-ft) of torque to the crankshaft. With a six-speed S tronic, the car completes the sprint from 0 to 100 km/h (62.14 mph) in 5.4 seconds. The combined fuel consumption of the four-cylinder turbo is 7.1 liters per 100 kilometers (33.13 US mpg).

The quattro drivetrain operates with an electronically-controlled hydraulic multi-plate coupling. The body was lowered 25 millimeters (0.98 in), and 17-inch brakes are mounted behind the 18-inch wheels. 19-inch wheels are also available in conjunction with Audi magnetic ride. Progressive steering is standard.

Audi A5 DTM, 2012

 

 

 

 

 Audi A5 DTM, 2012

On the eve of the 2011 International Motor Show (IAA) in Frankfurt Audi presented the new Audi A5 DTM: After the V8 quattro (1990 to 1992) and the A4 (2004 to 2011) the brand with the four rings has opted to use a two-door coupe in the most popular international touring car series for the first time.

The new Audi A5 DTM, which bears the internal project name "R17" at Audi Sport, conforms to the new Technical Regulations that will come into effect in the 2012 season. The project was premised on three key aims: the safety of the vehicles, reduction of the costs by up to 40 percent and a spectacular exterior design.

2011 IAA visitors will have the opportunity to get a first-hand impression of the new car's look at the Audi Hall from September 13th to 25th, 2011. The Audi A5 DTM appears lower and sturdier than its successful predecessor with which Audi has won four of the last seven DTM titles. Underneath the body, which is completely made of carbon, a new type of chassis features a hybrid construction. The combination of a carbon fiber monocoque and steel cage sets new standards in terms of safety for a race touring car. In addition, the chassis is one of more than 50 components which are identical for all DTM vehicles.

The Audi A5 DTM is 5.01 meters long, 1.95 meters wide and 1.15 meters low. The wheelbase of all DTM vehicles is identical, i.e. 2,750 millimeters. Like its predecessor, the A5 DTM is powered by a V8 engine with an output of about 340 kW (460 HP). The six-speed transmission, now pneumatically operated using paddle shifters in the steering wheel, is a new development. The shifting events are more precise compared with conventional manual gearshifts and allow the mileage of the unit to be quadrupled to up to 24,000 kilometers.

The engine electronics (Bosch MS 5.1), which operate without fuses, and the central display that is already being used in the Audi R8 LMS are state-of-the-art as well. The exclusive tire partner Hankook is supplying larger and wider tires with dimensions resembling those of LMP2 sports cars.

A safety fuel tank with a capacity of 120 liters is integrated with the carbon fiber cell of the Audi A5 DTM. It would allow the current distance of a DTM race to be covered without a refueling stop. For longer races a quick refueling system is in development.

The engine sub-frame at the front and the transmission at the rear are identical for all DTM cars and limit the freedom of the engineers with respect to the suspension, which has to be mounted to these shared components. In addition, steel as the material for the A-arms and the tube dimensions are specified. For the hub carrier, the regulations define the material and the production process to be used. A milled aluminum part with a minimum weight is prescribed. Furthermore, a strict provision in the regulations defines the wheel hubs and the rims for all entrants.

The possibilities in the area of aerodynamics are restricted as well. Air flow through the body, as in the case of the current A4 DTM, and complex additional wings at the rear are no longer allowed. This creates a stronger visual resemblance between the race car and the production model. At the same time the new DTM vehicles are to respond less sensitively to body contact with other vehicles and deliver slipstream improvements - also thanks to the larger rear wing.

Audi A1 e-tron Concept, 2010

 

 

Audi A1 e-tron Concept, 2010

The Audi A1 e-tron Concept is a Mega City Vehicle (MCV) with an innovative drive technology. It comes equipped with a powerful electric motor for zero-emission driving in the city. There is also an internal combustion engine on board that recharges the battery in exceptional circumstances. The Audi A1 e-tron Concept is very agile thanks to the 75 kW (102 hp) peak power of its electric motor.

The technology of the Audi A1 e-tron
The e-tron model family from Audi is just a few months old, but it already has a number of members, for each of which Audi has chosen a different drive technology. The first e-tron, which debuted at the 2009 IAA in Frankfurt/Main, is a near-series high-performance sports car with electric motors for all four wheels. The study shown at the Detroit Motor Show in 2010 is a lightweight, compact two-seater with two electric motors on the rear axle.

The Audi A1 e-tron Concept now presents another approach - a compact electric car in the premium class. The four-passenger, two-door MCV city car was designed specifically for use in the metropolitan areas of Europe and North America and in the rapidly growing megacities of Asia and South America. The Audi A1 e-tron always drives on electric power; its internal combustion engine is only used to recharge the battery in isolated cases.

The integration of the new technologies shows the holistic approach that Audi is pursuing with electric mobility. The objective is to use the energy with the lowest possible losses. The precise interaction of the components, their intelligent packaging, and the efficient management of the current flows are the product of the expertise that the company has developed in this area.

Audi has developed a proprietary thermal management system to keep the battery, the electric motor, and the power electronics within their respective ideal temperature windows.
Behind the three e-tron models is a broadly diverse and modular technology platform that continues to grow very rapidly as Audi drives development forward.

The electric motor: 75 kW (102 hp) peak power
The synchronous electric motor of the Audi A1 e-tron is mounted transversely at the front of the car. Its low mounting position has a positive effect on the vehicle's center of gravity. Continuous output is rated at 45 kW (61 hp), with peak power of 75 kW (102 hp) available in short bursts. 150 Nm (110.63 lb-ft) of torque is continuously available, and peak torque is 240 Nm (177.01 lb-ft).

The electric motor sends its power to the front wheels via a single-speed transmission. The elegant, retractable selector lever on the console of the center tunnel used to choose between "Drive," "Reverse," and "Neutral" was taken from the first Audi e-tron.

The power electronics are mounted in the engine compartment above the electric motor. The most important components are the pulse-controlled inverter, which serves as the controller between the electric motor and the battery; the DC converter, which connects the high-voltage network with the 14 volt electrical system; a breaker unit to protect the high-voltage components; and the charging module. The socket for the standard charging plug is located behind the rings in the single-frame grille of the Audi A1 e-tron. A fully depleted battery can be recharged in approximately three hours from the 380 volt grid. A display immediately adjacent to the plug-in connection shows the current charge status and the charging time remaining.

The concept of the innovative Mega City Vehicle requires the electrification of key auxiliaries. The refrigerant compressor of the climate control system, for example, is electrically powered by a high-voltage electric motor that supplies only the amount of power needed at the time.

The increases system efficiency substantially compared to conventional concepts. Thanks to a special circuit, the climate control loop also functions as a heat pump that regulates the temperature of the cabin and the battery.

The power steering of the Audi A1 e-tron is electro-mechanical and thus particularly energy-efficient. An electronic brake system makes it possible to tap into the recuperation potential of the electric motors. A hydraulic fixed-caliper brake is mounted on the front axle, with two novel electrically-actuated floating-caliper brakes mounted on the rear axle. These floating calipers are actuated not by any mechanical or hydraulic transfer elements, but rather by wire ("brake by wire"). In addition, this eliminates frictional losses due to residual slip when the brakes are not being applied. In addition, the servo unit received a new, demand-controlled electric vacuum pump.

The large electric motor powering the Audi A1 e-tron Concept can convert braking energy into electric current and feed it back into the electrical system. The high degree of recuperation benefits overall efficiency. The electric control actions are imperceptible to the driver, who notices only the familiar, precise, and perfectly controllable pedal feel.

The battery pack: a compact T arranged below the floor
The energy storage unit is arranged below the floor, where it is ideal for the center of gravity and weight distribution. The battery pack is shaped like a T, with the short "transverse beam" filling the rear section of the center tunnel and the "cross-beam" filling that area in front of the rear axle where the fuel tank is otherwise located. The 380 volt lithium-ion rechargeable battery has a nominal energy content of 12 kilowatt hours. It comprises 96 prismatic cells and weighs less than 150 kilograms (330.69 lb).

The Audi A1 e-tron can drive 50 kilometers (31.07 miles) emission-free in city traffic on the powerful battery. On longer trips, the battery is recharged by a particularly compact internal combustion engine mounted below the luggage compartment.

The range extender
The Audi A1 e-tron Concept car has a Wankel engine as a range extender, but other compact concepts are also possible. The small single-rotor Wankel has a chamber volume of 254 cc and runs at a constant 5,000 rpm in its peak efficiency window. The electronics also consider navigation data such as the destination and route profile to automatically activate the range extender as needed. The driver can also turn the range extender on and off as necessary with the push of a button The fuel tank holds 12 liters (3.17 US gallons).

The great strengths of the Wankel engine are the nearly vibration-free and quiet operation, the small dimensions, and the extremely low weight. Together with the generator, which is powered by the Wankel engine and produces 15 kW of electric power, the complete assembly weighs only around 70 kilograms (154.32 lb). This weight also includes the special power electronics, the intake, exhaust, and cooling unit, plus the insulation and the sub frame.

Driving experience
The first defining impression that the driver of the Audi A1 e-tron gets is that of nearly total silence. Even the Wankel engine in the back can barely be heard when it is running.

The second characteristic perception is the power of the electric motor, nearly all of which is available instantly and thrusts the Audi A1 e-tron forward with authority. The innovative Mega City Vehicle, which despite its complex drive technology weighs only 1,190 kilograms (2,623.50 lb) delivers zero-emission driving fun in a modern and sophisticated manner. The vehicle accelerates from 0 to 100 km/h (62.14 mph) in 10.2 seconds and has a top speed of more than 130 km/h (80.78 mph).

The Audi A1 e-tron can also cover longer distances if the range extender charges the battery. The extra range, which is intended primarily for interurban driving, is 200 kilometers (124.27 miles).
According to the draft standard, the two different operating modes yield a fuel consumption of only 1.9 l/100 km (123.80 US mpg), which corresponds to CO2 emissions of 45 g/km (72.42 g/mile). In electric mode, there are zero local CO2 emissions - the compact Audi A1 e-tron Concept is thus ecological and economical.

The third impression that the Audi A1 e-tron Concept makes is that of a larger car. The compact two-door boasts all of the strengths of the new A1 model series - the carefully tuned, sporty chassis with specially designed 18 inch alloy wheels and 215/35 R18 tires; the generous, "grown-up" interior; the excellent fit and finish; and a multitude of high-end equipment.
The dark shade "ebony" dominates the interior. The seats - with stone gray seams - and the headliner are in "Alabaster White".

The Design
The concept car in Geneva has a special "Aqua Mint, pearl effect" paint finish; the contrasting roof arch is offset in "High Gloss Steel dark." As with the other two e-tron models, the 18-inch wheels with a 20-spoke turbine design convey the high-tech aspiration of the concept.

The rear diffuser with aluminum trim lacks tailpipes. This emphasizes the width of the vehicle and suggests the low emissions. The two front fenders are emblazoned with the "e-tron" logo.

Audi A4 allroad quattro, 2010

 

 Audi A4 allroad quattro, 2010

The Audi A4 allroad quattro features all the innovative technologies which impart to the A4 model line its superiority: a range of powerful and highly energy-efficient engines, Audi drive select (intelligent handling technology), the high-tech S tronic transmission, and innovative communication and assistance systems. The vehicle will be available in early summer at a basic price of 37,100 euros.

The design of the Audi A4 allroad quattro recalls the Audi A4 Avant: crisp lines enclose tastefully curved surfaces and the low roof line establishes a coupé-like silhouette. Striking details re-interpret this model line's sporty elegance. The moon-gray single-frame radiator grille bears vertical chrome strips; an accentuated bumper and large air inlets underscore this vehicle's unique identity. Chrome rings encircle the fog lights. And in the option featuring xenon plus headlights, light-emitting diodes comprise the daytime running lights and taillights. Underneath the front end and tail end, the A4 allroad has a stainless-steel underbody guard.

The Interior
Refined touches, uncompromising quality and flawless functionality: the interior of the Audi A4 allroad quattro embodies all the strengths for which Audi is renowned. The cockpit clearly serves the driver. Among the control unit's highlights: the standard electromechanical handbrake - which has replaced the lever on the center console with a button - and the central on-board monitor. A color display complements the concert or symphony sound system, or the MMI navigation system plus; the MMI's offset control unit is housed in the center console.

The Engines
Audi will initially offer three different engines for the Audi A4 allroad quattro: a gasoline engine and two diesel engines. All three are turbocharged direct-fuel-injection engines. They command respect due to excellent performance, impressive pulling power, smooth running, and high fuel efficiency. The engines are further bolstered by pioneering technologies arising from Audi's modular efficiency expertise. For example, all three units boast a standard on-board recuperation system, which converts mechanical energy into electrical energy during deceleration.

The Driveline
The 2.0 TDI transmits its power to a six-speed manual transmission. The 3.0 TDI and 2.0 TFSI feature the next generation of Audi's dynamic and very efficient S tronic. This innovative dual-clutch transmission switches extremely smoothly among its seven gears within a few hundredths of a second. S tronic also excels thanks to its high efficiency ratio and a broad spread of the gear ratios. The seven-speed S tronic has a fully automatic mode at the ready: the driver can shift as required, if necessary via shift paddles on the steering wheel.

The differential is in front of the clutch and immediately behind the engine. This technical stroke of genius made it possible to reposition the front axle much closer to the vehicle's front end, in turn allowing for a long wheelbase and an ideal distribution of the axle loads. The benefits include steady straight-line stability, superb ride comfort, and excellent driving dynamics.

The Audi A4 allroad quattro features quattro permanent all-wheel drive as standard equipment. Its purely mechanical center differential favors the rear, distributing power at a 40:60 ratio to the front and rear axle. If necessary, the quattro permanent all-wheel drive can route up to 65 percent to the front or as much as 85 percent toward the tail end.

The Chassis
The width of the Audi A4 allroad quattro lays the foundation for its driving dynamics. The car's track is 1,583 mm (62.32 in.) at the front and 1,574 mm (61.97 in.) at the rear - some 20 mm (0.79 in.) wider, respectively, than the A4 Avant. The body is higher on account of a new chassis with longer springs, which - like the new shock absorbers - combine sportiness with comfort. The standard, 17-inch lightweight alloy wheels are fitted with 225/55 tires. At a diameter of 690 millimeters (27.17 inches), even this standard configuration looks rather imposing. For the time being, Audi is also offering 18-inch wheels.

The chassis in the Audi A4 allroad quattro retains all the advantages which distinguish the A4 model line. Steering is straightforward and responsive. A steering box beneath the wheel conveys the driver's input directly to the wheels. The five-link front suspension and the self-tracking trapezoidal-link rear suspension consist largely of aluminum to reduce unsprung weight. 16-inch brakes with excellent cooling behavior provide for rapid deceleration. It should come as no surprise that the Audi A4 allroad quattro offers sportiness, comfort, and stability - onroad and offroad. After all, it is an A4.

Audi drive select further enhances the joys of driving. This control system automatically and perfectly adapts the personality of the Audi A4 allroad quattro to the driver's preferences. Audi drive select namely evaluates the engine's throttle response, the Servotronic power steering, and S tronic's shift points in automatic mode. The driver can freely switch among three different engine maps: comfortable, standard, and sporty. And MMI navigation plus provides yet another on-board control option, and is individually programmable.

The Audi drive select can be paired with Audi dynamic steering. It consists of a superimposed gear system, and varies the steering ratio as well as steering assistance in a continuously variable manner. Audi drive select functions directly at low speeds and indirectly at high speeds. At the vehicle's cornering limit, the dynamic steering keeps the Audi A4 allroad quattro on course via split-second corrective actions - subsequently obviating extensive ESP intervention.

Audi A1, 2011

 

 

 

Audi A1, 2011

The interior of the Audi A1 is also sporty and of high quality. Customers can customize numerous details to tailor the car to their personal tastes. Audi's latest model has a broad portfolio of advanced technologies on board; its infotainment system sets new standards in the segment. The Audi A1 is the first premium automobile in the small compacts class - a true, fully-fledged Audi.

The Audi brand stands for automotive passion. With its agile chassis and powerful engines, the Audi A1 is the sportiest car in its class, and this is readily apparent at first glance. The design is unique and modern. Styling cues placing the Audi A1 in the Audi family include the side line with the distinctive roof arch, the coupe-like C-pillars, the large wheel wells and, of course, the front end with the typical single-frame grille. The hood and rear hatch encompass the body; the tail lights are three-dimensionally molded and present an unmistakable design, day or night.

The interior: airy and dynamic
The interior of the Audi A1 is spacious and airy. The instrument panel is suggestive of an airplane wing; its four round air nozzles are reminiscent of the turbines of a jet. The clear ergonomics and the uncompromisingly high fit and finish typify the Audi brand's high standards. Many lovingly designed details in the interior document the premium character of the Audi A1.

Concentrated driving pleasure: the sportiest car in its class
The sporty, agile chassis of the Audi A1 places it at the head of its class. Whether in the city, on an interurban road or on the highway - the Audi A1 is great fun to drive anywhere thanks to its sporty setup, the optimized weight distribution and the very direct steering. The standard ESP stabilization system with electronic axle-differential lock makes the handling of the Audi A1 even more sporty and precise, while driving safety is increased even further.

The new Audi A1 also sets new efficiency standards. Audi is sending the new model line into the fray with four four-cylinder engines, with the two TDI and two TFSI gasoline engines producing between 63 kW (86 hp) and 90 kW (122 hp). All of the engines follow the downsizing principle - they substitute turbocharging for displacement and draw their fuel through direct injection units.

All versions of the Audi A1 impress with good fuel economy, with standard cycle values between 3.8 and 5.4 liters per 100 kilometers (43.56 - 61.90 US mpg) (provisional values). The 1.6 TDI with 66 kW (90 hp) and manual transmission emits only 99 g of CO2 per kilometer (159.33 g/mile). All of the engines are equipped with a recuperation system that allows them to recover energy during braking, and are coupled with an automatic start-stop system. A new temperature management system with switched water pump contributes to the low fuel consumption of the 1.2 TFSI.

High-tech and efficiency: the seven-speed S tronic
At Audi, efficiency is always high-tech. The Audi A1 is available with the seven-speed S tronic transmission. The dual-clutch transmission changes gears extremely quickly, comfortably and without detectable interruptions in pulling power. It offers both automatic and manual modes, with paddles on the steering wheel available as an option. It provides for tremendously fun driving and also further reduces fuel consumption - typical Audi.

The Audi A1 is sporty, powerful and attractive. As a newcomer in the compact segment, it appeals to a modern customer group - a young, urban, lifestyle-oriented public. Audi A1 customers - many of whom are expected to be women - are interested in design, music, fashion and sports. The entry-level model will be priced at around 16,000 euros.

Design
It has a confident road stance - powerful, distinctive and full of character: The Audi A1 is both the premium option and the athlete in its class. The pronounced encompassing shoulder line, the color-contrasted roof arch and the unusually sharply sloping C-pillars give the three-door an unmistakable silhouette. The dimensions also document the dynamic lines: 3.95 meters (12.96 feet) long, the latest model from Audi is an impressive 1.74 meters (5.71 feet) wide but only 1.42 meters (4.66 feet) tall. The wheelbase measures 2.47 meters (8.10 feet); the overhangs are correspondingly short.

The design of the Audi A1 is tightly integrated into the brand's design language and unique in the compact segment - emotional, bold and progressive. Audi has a reputation for taking a lot of ideas and innovations from its concept cars into series production, and the Audi A1 continues this tradition. Many of the features and innovative ideas from the 2007 Audi A1 project quattro showcar have already made it to series production in the Audi A1.

The front end bears an unmistakable family resemblance, but features unique accents and innovations in the details. The single-frame grille, for example, is harmoniously integrated into the front end and with its angled top corners represents a new evolutionary stage. Its braces are arranged horizontally to emphasize the width of the front. The large, plastically modeled air intakes with their horizontal bars also contribute to the sporty appearance of the Audi A1. The fog lights are located in their outer corners.

The three-dimensionally styled headlights also have their own special look. The Audi A1 looks determined and concentrated to the road. A strongly curved wing structures the interior of the headlights. As with every Audi, the daytime running lights are standard. With the optional xenon plus units, the daytime running lights are implemented using LEDs and a light guide. They appear as a homogenous strip that traces the wing.

Powerful design element: the tornado line
The most striking impression when viewed from the side is the straight, slightly upward course of the lines, which visually stretch and accelerate the Audi A1. The upper edge of the hood extends below the side windows to the rear end. As with the Audi TT sports car, the point where the encompassing hood meets the fenders is the point of origin for a typical Audi design element - the tornado line. It continues in the door and the rear flank. The line runs closely and precisely above the wheel wells, giving the Audi A1 a powerful road stance.

The heavy shaded edge beneath the tornado line, the powerfully arched sheet metal surfaces on the flanks and the rising dynamic line above the sills are also characteristic of the brand's design language. The same is true of the expressively shaped wheel wells, which provide shelter to wheels measuring up to 18 inches, and for the ratio of sheet metal surfaces to the greenhouse, which is two-thirds to one-third. The side mirrors are mounted on the doors like with a sports car; the door handles are distinctly bow-shaped.

Body
An Audi truism also applies to the Audi A1: The body establishes the foundation for the quality, for the precise, sporty handling and for safety. Two-thirds of the body comprises high- and ultra high-strength steels of different strength classes.

The strongest of these are the hot-shaped steels. The blanks are heated in a furnace to extreme temperatures then immediately shaped in a water-cooled pressing die. This rapid change in temperature imparts them with extreme tensile strength. Hot-shaped steels make up a good 11 percent of the body. They are used for the lower crossmember in the footwell, in the rear sections of the longitudinal members, in the B-pillars and in the roof frame - anywhere extreme strength combined with low weight is particularly important.

The high- and ultra high-strength steels are a significant factor for the high torsional rigidity of the body and its low weight of only 221 kilograms (487.22 lb). These two values and the dimensions are used to compute the high lightweight quality of the superstructure while also providing the basis for a high level of occupant protection.

The Audi A1 comes standard with two front airbags, side airbags in the backrests of the front seats and two curtain head airbags. Belt tensioners and belt force limiters plus the Audi integral headrest system round out the package of retention systems. Isofix child seat anchor points in the rear are standard. Belt buckle sensors at all seats are another increased safety feature. And when it comes to pedestrian protection, the Audi A1 is also equipped with cutting edge technology.

Low-speed collisions - light bumps in parking lots and the so-called typical claim crash so important for the insurance rating - do not result in any major damage. The layout of the bumpers, the crossmember behind them and the longitudinal members protect cost-intensive components such as the radiator and air conditioners.

Aerodynamically optimized: from the front skirt to the rear spoiler
With 0.32 coefficient of drag for the base model, the newest Audi is among the most aerodynamic cars in its class. This is the result of extensive fine-tuning at the Ingolstadt Wind Tunnel Center. The entire body has been optimized - from the rear spoiler, including the spoiler edges, to the underbody and the wheels. The aerodynamic underbody largely covers the underbody, protecting it and creating favorable aerodynamic air flow.

The corners and other edge regions of the skirts feature a sophisticated design that not only sinks the coefficient of drag, but also improves driving stability at high speeds. The area around the grille is completely sealed so that the inflowing air reaches the radiator with virtually no losses instead of becoming turbulent. Even such subtleties as the flow of air through the engine compartment have been optimized to the finest detail with respect to thermo- and aerodynamics.

Another of the body's strengths is its acoustics. The Audi development engineers devoted considerable attention to the sound radiation of the large sheet metal panels and their rigidities. All regions at which forces are induced during driving were specially reinforced. A lightweight insulation package brings the acoustics in the passenger cabin up to the premium level.

The Audi A1 will be built at the Audi plant in Brussels. Audi invested more than 100 million euros in the modernization of the production facility in order to completely satisfy the most stringent of quality standards.

Interior
Sportiness, precision and youthful freshness - these themes characterize the interior of the Audi A1. The designers looked to airplane wings for inspiration for the elegantly curving instrument panel. The four round, far-protruding air nozzles are reminiscent of the turbines of a jet.

The center console, with its integrated strip of secondary switches, resembles the stern of a yacht and appears to float above the center tunnel. The control unit for the climate control system and the three cylindrical rotary dials of the optional automatic climate control system are another optical and haptic highlight on board the Audi A1. The instrument panel is also home to the head unit for the radio or the optional MMI control and infotainment system. The display, which is standard with the concert radio or higher, is retracted into the instrument panel and extends upward at the push of a button. This installation position, ideal for quick reading, is a unique selling point in this vehicle class.

Helpful: the on-board computer with efficiency program
The on-board computer with efficiency program is linked to the driver information system. It displays data relevant to fuel consumption and gives recommendations for efficient driving. An enlarged view of the gear-change indicator signals to the driver when he or she should change gears. Another function provides information on which on-board consumers, such as the climate control system or the rear window defogger, are active and how much fuel they are consuming.

The seats in the Audi A1 offer great hold, guidance and support and seat persons of all sizes extremely comfortably. A height-adjustable driver's seat is standard. The Ambition trim line includes sport seats with lumbar support, and the passenger seat also comes height-adjustable as standard. The easy-entry function for comfortable access to the back is also standard with the Ambition package.

Plenty of storage is available at every seat - two cup holders on the console of the center tunnel, pockets in the doors and the rear side trim as well as a power outlet. On the base model, there is a fold-up compartment on the instrument panel instead of the on-board monitor. Audi also offers an optional storage package with additional stowage options.

The premium character of the Audi A1 is expressed in every last detail of the interior - in the selection of the materials, in their fit and finish and in the tight, even gaps. The surface of the instrument panel is softly backed with foam; all buttons and controls move precisely; even the pull handle that unlatches the hood release does so crisply and precisely.

Standard with the Ambition trim line and optional with Attraction are numerous aluminum-look control elements, including the entry strips, the dials for the automatic climate control system and the light dials. Furthermore, the ring of the three-spoke sport steering wheel, the parking brake handle and the gear shift lever are wrapped in leather and adorned with subtle aluminum clips.

Youthful and new: colors and materials
The materials in the interior vary between the two lines. Attraction features black or titanium gray cloth upholstery with the center console, armrest, map pocket and speaker grills also being titanium gray. The sport seats in the Ambition line have a two-color design featuring titanium gray or wasabi green as a contrasting color to black. The interior is also available in black. The media style package offers velvet beige as an alternative. The optional leather seats available with the Ambition line and the media style package are offered in a choice of three colors and three combinations.

Everything about colors and trim is novel, youthful and lifestyle-oriented. The air nozzle housings are available in a wide range of colors - with matt or high-gloss black standard depending on the trim line. They are also optionally available in high-gloss white, titanium gray, wasabi green, red or velvet beige to match the color of the trim. Audi also offers a range of attractive colors for the door armrests and the console on the center tunnel for all trim lines.

Infotainment systems
The Audi A1 is a premium automobile for modern people - it offers a range of state-of-the-art infotainment and multimedia systems directly from the luxury class.
The infotainment system comprises modular components based around the standard chorus radio, which has an mp3-capable CD drive and GALA speed-dependent volume control. The chorus radio delivers its sound to four loudspeakers.

The next step up features the new concert radio, a versatile device that is likewise equipped with a CD drive. The separate, retractable on-board monitor - a high-resolution, 6.5 inch color display - is standard with this radio. It also features a dual tuner, an SDHC memory card reader, an AUX-in connection and six loudspeakers front and rear.

The concert radio also unlocks the choice of the optional connectivity package, which includes a navigation system preparation. This allows the customer to add an Audi map-based navigation unit to the radio at a later time. The required hardware is already installed in the radio. The customer can purchase the system activation and an SDHC card with the navigation data through Audi Genuine Accessories at any time. Activation is performed by the Audi dealer. The connectivity package also includes a Bluetooth interface, an SDHC card reader and the Audi music interface.

The top of the line is MMI navigation plus, a high-end media center that is a benchmark in the compact vehicle class. It comprises four primary components - the main unit with a 60 gigabyte hard drive, the radio unit, the MMI control terminal and the color display. The retractable 6.5 inch display features elegant images. It displays its graphics as well as the cover art for the audio titles. The navigation map is also displayed in 3D.

Classic Audi logic: the MMI control terminal
With its intuitive logic, the MMI control terminal is structured similarly to the units from the large Audi models. A large rotary pushbutton is at the center of the unit. It can be rocked in four directions like a joystick, which makes many functions even more convenient. A variety of hard and soft keys, a volume control, and slots for the storage media are arranged around and above the central controller.

Drivetrain
Audi will initially offer the Audi A1 with four engines. The two TFSI gasoline engines and the two TDI diesels cover a power range from 63 kW (86 hp) to 90 kW (122 hp). Each of them is state-of-the-art.

All of the engines employ direct fuel injection and turbocharging. This downsizing concept coupled with technologies from the Audi modular efficiency platform give them tremendous power with minimal fuel consumption ranging from 3.8 to 5.4 liters per 100 km (43.56 - 61.90 US mpg).

The entry-level gasoline engine is the new 1.2 TFSI. It generates 63 kW (86 hp) and produces its peak torque of 160 Nm (118.01 lb-ft) already between 1,500 and 3,500 rpm. Coupled with a five-speed manual transmission, the four-cylinder accelerates the Audi A1 from 0 to 100 km/h (0 - 62.14 mph) in 12.1 seconds on its way to a top speed of 179 km/h (111.23 mph). In the EU driving cycle, it consumes only 5.1 liters of fuel per 100 km (46.12 US mpg), which corresponds to only 119 grams of CO2/km (191.51 g/mile).

Downsizing from Audi: turbocharging instead of displacement
The newly developed four-cylinder exemplifies the Audi philosophy of downsizing, the substitution of turbocharging for volume. The engine with two-valves per cylinder displaces only 1,197 cc and has been rigorously optimized for low weight and low friction. Its cast aluminum crankcase has its own cooling loop separate from the cylinder head. The water in the block is not circulated immediately after the engine is started, enabling the engine to come up to temperature more quickly and shortening the phase of increase frictional resistance due to cold oil.

The 1.4 TFSI ups the ante with 90 kW (122 hp). Its peak torque of 200 Nm (147.51 lb-ft) is continuously available between 1,500 and 4,000 rpm. A turbocharger with a water-cooled intercooler pressurizes the 1,390 cc engine with four valves per cylinder.

Together with the seven-speed S tronic, the 1.4 TFSI gets the Audi A1 up to highway speed in 9.1 seconds. Top speed is 200 km/h (124.27 mph). The standard six-speed manual transmission bumps the time for the sprint to 9.2 seconds, but does not affect top speed. Average fuel consumption is just 5.1 and 5.4 liters/100 km (43.56 and 46.12 US mpg), respectively, in the EU test cycle.

The power output of the new 1.6 TDI comes from a displacement of 1,598 cc. Internal friction in the compact four-cylinder has been systematically minimized. Audi offers two versions of this engine. The more powerful 1.6 TDI unit produces 77 kW (105 hp) and 250 Nm (184.39 lb-ft) between 1,500 and 2,500 rpm, and is coupled with a five-speed manual transmission. The 16-valve engine accelerates the Audi A1 powerfully through the standard sprint in 10.8 seconds before reaching a top speed of 187 km/h (116.20 mph) while consuming an average of just 3.9 liters/100 km (60.31 US mpg).

The second version of the 1.6 TDI generates 66 kW (90 hp) and 230 Nm (169.64 lb-ft) of torque between 1,500 and 2,500 rpm. Coupled with the five-speed manual transmission, it accelerates the Audi A1 from 0 to 100 km/h (0 - 62.14 mph) in 12.2 seconds. Its reaches a top speed of 179 km/h (111.23 mph) and offers exemplary fuel economy of 3.8 liters/100 km (61.90 US mpg), which corresponds to 99 grams of CO2/km (159.33 g/mile).

All four engines in the Audi A1 use a technology from the Audi modular efficiency platform - the recuperation system uses an intelligent voltage controller for the generator to recover energy during the braking and coasting phases and store it temporarily in the battery. The next time the car accelerates, this energy flows back into the on-board electrical system, relieving the load on the generator.

The 4 engines also come standard with a second technology from the Audi modular efficiency platform - the start-stop system. This turns the engine off when the car is at rest, if the gear selector lever is in neutral and the driver's foot has left the clutch pedal. Start-stop then turns the engine back on as soon as the clutch pedal is depressed — all the while functioning quietly, conveniently, and quickly.

Chassis
The front-wheel-drive Audi A1 is the sportiest car in the compact class. It is nimble and agile in the city; steady and precise on interurban roads, and comfortable on the highway. It owes these qualities primarily to the highly advanced chassis with the wide track and balanced weight distribution.

The engineers devoted a great deal of attention to the distribution of axle loads during the development of the Audi A1. Measuring only 81 centimeters (31.89 inches), the front overhang is unusually short. Depending on the engine, only between 61 and 63 percent of the weight rests on the front axle, a low value for a compact car. A number of details contribute to this, such as the position of the battery, which with most engine options is underneath the luggage compartment. With a base weight of only 1,045 kilograms (2,303.83 lb), the Audi A1 is the lightest vehicle in the premium compact class.

The front suspension comprises a MacPherson construction with lower triangular wishbones. The steering impulse from the electrohydraulic rack-and-pinion power steering, which is more efficient than a straight hydraulic system, is transferred via short paths to the pivot bearing for spontaneous steering response and precise, sensitive feedback through the steering wheel.

Direct: the power steering
At a ratio of 14.8:1, the steering is sportily direct, requiring only slight steering angles at the wheel. The high turn-in of the front wheels keeps the turning circle to 10.6 meters (34.78 feet) - both factors give the Audi A1 the ultimate in agility in city traffic as well as on open roads.

The Audi A1 comes equipped with a new Audi technology regardless of the engine selected - the ESP stabilization system also includes an electronic differential lock. Similar to a mechanical locking differential, it makes the already agile handling even more neutral by largely eliminating understeer and improving traction. If the electronics detect that the load on the front inside wheel is reduced too much, it initiates brief, controlled braking of that wheel. The excess torque then flows to the outside wheel, which can apply more power to the road. Road behavior is even more precise, agile, stable and neutral, further enhancing objective safety and subjective confidence in the car.

High performance: the wheel brakes
The sporty performance, top-class safety and comfort required in the premium compact class place high demands on the brakes. The brake system of the Audi A1 was selected specifically for the performance of the different variants.
Even the models with the entry level engines should therefore have plenty of braking power in reserve. Every vehicle comes equipped with ventilated disc brakes up front and massive brake discs in the rear.

Sport steering wheel
In keeping with the vehicle's sporty character, the Audi A1 comes standard with a grippy three-spoke sport steering wheel that can be optionally wrapped in fine Nappa leather and trimmed with high-quality chrome-design elements.

Equipment and trim
The Audi A1 in two trim levels. Attraction is the richly appointed charismatic version; Ambition the sporty and dynamic variant. Both lines can be combined with the media style package, which offers attractive infotainment and interior design options. Features such as the navigation package can also be purchased later, keeping the Audi A1 fresh and attractive for years to come. The latest member of the Audi family also follows a fresh, young line with respect to materials and colors in the interior.

The Attraction line comes equipped with a number of comfortable features - the chorus radio, a radio remote-controlled central locking system, power-adjustable side mirrors, power windows and a height-adjustable driver's seat. Standard passive safety features include two front airbags, side airbags and head airbags. Belt force limiters, the integral Audi headrest system and Isofix anchor points for child safety seats in the rear round out the program.

The Abt R8: Sports car in perfection

There are cars and dream cars. The latter includes Lamborghini's Gallardo, Ferrari's F430 or Porsche's 911 Turbo. These cars make your heart beat faster and show the perfected magic of speed on the roads. Abt Sportsline's R8 will also be among these outstanding super sports cars and is getting ready to overtake them in the prestige duel.

The design studies already show the first impressions of Abt's sportiest creation - and prove that the Kempten-based tuner manages to perfect an excellent serial model like the R8 to detail and accentuate its racing genes already in the drawing. The front of the Bavarian R8 shows the marked Abt face. Together with the unique and beautiful rear with its four inclined arranged exhaust end pipes, the rear diffuser and the extravagant rear wing, the front of the Abt R8 is part of an overall concept that brings about phenomenal roadholding. The add-on parts of the super sports cars from the Allgäu-region improve downforce and ensure perfect balance of the front and rear axis. This is especially notable in speed ranges reserved for only a few cars. The sideblades which were developed especially for the Abt R8 and the Abt side skirts give the Abt R8 a new and individual design besides aerodynamical advantages. The aerodynamically efficient Abt body kit, which also includes carbon-fibre parts, is a real eye catcher but also shows the state-of-the-art Bavarian precision work. With the ingenious construction, which also includes a carbon-fibre bonnet, not only a maximum reduction in weight is achieved but it also ensures optimized weight distribution of the Abt R8 - the pure presence of the model athlete already shows this.

The technology and the design milestones do not only come from Maranello or Sant'Agata-Bolognese but also from Kempten. The Abt R8 will be a gorgeous dream car with the genes of a top-class race car. This special automobile will belong to one of the fastest among the fastest; the Abt R8 will also challenge the Lamborghinis and Porsches. With regards to the anticipated performance data the Bavarians are traditionally discreet. But this data already amazes sports car fans and makes them want to spur the hot-blooded Bavarian horses. 530 HP (390 kW) are to be drawn from the 4.2 litre-V8 thanks to the Abt supercharger. Compared with the serial model which already shows impressive performance data this means an increase of 110 HP (81 kW). The brand new Abt 20-inch BR wheels stylishly transfer this power onto the asphalt. The all-wheel-drive dream car accelerates from 0 to 100 km/h in just 3.9 seconds and reaches a top speed of 317 km/h. These values are synonymous with magic and this extraordinary super sports car desperately wants to be driven. By means of the Abt suspension which is adjustable in height, pressure and rebound, the performance and driving comfort of the super sports car can be adapted perfectly to the requirements of its driver.
