Nissan 370Z Roadster, 2010
The Truly Authentic Roadster
The Nissan 370Z Roadster's most obvious departure from the 370Z Coupe is its convertible top. The soft-top roof was designed with an emphasis on three key areas: to provide a sleek silhouette matching the new Z®'s stunning styling with the top up or down, to offer easy single-action open-close operation, and to provide an enjoyable top-down experience with reduced wind turbulence and all-climate driver/passenger comfort.
With convertible top in the closed position, the design provides a sophisticated sloped-back appearance, the perfect balance between the soft top and the Z® body design. The shortened windshield and aerodynamically rounded rear deck enhance the Z's kinetic and dynamic character lines. When in the down position, the convertible top is concealed beneath a full body-color hard tonneau cover, which extends forward to help create the Z Roadster's classic "double cockpit" style interior.
Like the new 370Z Coupe, the Z Roadster's new exterior is more aggressive in appearance and lighter and tighter in structure than the previous generation. The wheelbase is nearly four inches shorter (100.4 inches versus 104.3 inches) and overall length is reduced by 2.6 inches (167.2 inches versus 169.8 inches). The new Z Roadster features an aluminum hood, door panels and trunk for reduced weight. At the same time, the body structure was extensively revised, improving rigidity and stability. The Nissan 370Z Roadster includes additional structural reinforcement (over the 370Z Coupe), including in the A-pillars and side sills.
The Inside of stunning exterior, true to its sports car heritage, the Z Roadster's interior is completely driver-centric, with its three-layer design grouping items by how a driver sees information, operates the controls and is held in place - so drivers feel completely connected and engaged whenever and wherever they drive, top up or down.
The Z Roadster features high back black woven "Carbon" cloth seats with 8-way manual driver's/4-way manual passenger's seat adjustments. Touring models include unique leather-appointed "net" seats with 4-way power/4-way manual operation on the driver's seat (4-way power on the passenger's seat). These second-generation net seats are exclusive to the Z Roadster and have integrated heating and cooling functions - ideal for open air driving no matter what the outside temperature.
The Z Roadster's 2-seat layout includes a deeply scooped instrument panel with a full-length center console separating the driver and passenger's seat. The instrument panel retains the traditional Z® 3-pod cluster with oil temperature, voltmeter and clock, while the speedometer and tachometer now include an "initial sweep" function, coming alive when the car is first started.
The sporty steering wheel is a new "oval" 3-spoke design, which offers baseball-style stitching, improved thumb grips and palm rest areas for improved feel on long drives. The surface of the leather-wrapped wheel is "shaved" to provide a more kidney-like shape to better fit in the hand. The manual transmission shifter is specially padded to improve the accuracy of diagonal shifts and to feel softer in the hand for forward and backward motions.
Open Air, Open Roads - An Unbeatable Combination
Roadster or Coupe, the new Zs share one of the most advanced drivetrains available for affordable sports cars today. The Z Roadster's long list of cutting edge performance-focused technologies includes a standard 332-horsepower 3.7-liter DOHC V6 engine with Variable Valve Event and Lift Control (VVEL), choice of 7-speed automatic transmission or close-ratio 6-speed manual with available "SynchroRev Match" (the world's first synchronized downshift rev matching manual transmission), refined 4-wheel independent suspension and 4-wheel vented disc brakes (with available Nissan Sport Brakes).
Compared to the previous generation 350Z Roadster, the new Z® convertible picks up 26 horsepower and 2 lb-ft of torque (332 horsepower @ 7,000 rpm and 270 lb-ft of torque @ 5,200 rpm, compared with the previous 3.5-liter V6's 306 horsepower @ 6,800 rpm and 268 lb-ft of toque @ 4,800 rpm).
The 3.7-liter engine gives better power delivery all the way to the 7,500 rpm redline, improved low-end power and more high-end torque, creating an entirely new driving experience. Key to the enhanced performance is the VVEL system, which is able to optimize intake valve open/close movements, allowing the needed air to be sent promptly to the combustion chamber at the precisely optimized time. Since the VVEL system can adjust to open the valves slightly, it improves fuel efficiency by reducing camshaft friction and fuel waste. It also provides cleaner emissions by allowing for quicker warm-up of the catalyst and by stabilizing combustion when the engine is cool.
The 2010 Z Roadster is offered with a choice of two new advanced transmissions - a close-ratio 6-speed manual or 7-speed automatic. The 6-speed manual is available with SynchroRev Match (included in the optional Sport Package), which allows drivers of any skill level to experience professional-like gear shift performance. The SynchroRev Match function automatically controls and adjusts engine speed when shifting to the exact speed of the next gear position, essentially "blipping" the throttle to smooth out any up/down shifts. This not only allows the driver to focus more on braking and steering, it improves vehicle balance and smoothness by reducing the typical "shock" when the clutch is engaged. The system can be deactivated with a button next to the shifter for drivers who prefer less vehicle intervention.
The 7-speed automatic includes Downshift Rev Matching (DRM) and Adaptive Shift Control (ASC) and is designed to offer quick, manual-like shifting when operated in manual mode.
Drivers can use the standard paddle shifters or the shift lever. The 7-speed's wide gear ratios offer improved fuel efficiency, while the Adaptive Shift Control is designed to adjust to the driver's driving style.
The Z Roadster also utilizes the Z Coupe's advanced 4-wheel independent suspension. The double-wishbone front suspension (which replaces the lower multi-link setup in the 350Z) uses lighter forged aluminum arms and a lightweight rigid aluminum-alloy cradle, along with a lighter stabilizer bar with a 35 percent improved lever ratio. The 4-link rear suspension is also stiffer and lighter, with the rear cradle entirely integrated into a single part. "High response" shock absorbers are utilized on each corner for improved ride comfort.
The Z's standard 4-wheel vented disc brake system includes Anti-Lock Braking System (ABS) with Electronic Brake force Distribution (EBD) and Brake Assist (BA). The optional Sport Package includes Nissan Sport Brakes with large diameter 14.0-inch front and 13.8-inch rear rotors (versus 12.6-inch front/rear standard rotors) with 4-piston front and 2-piston rear aluminum calipers.
Steering is provided by a vehicle-speed-sensitive power-assisted rack-and-pinion design. Unwanted steering kickback and vibrations are reduced with the addition of a solenoid valve that acts like a damper when there is a harsh impact load. A Vehicle Dynamic Control (VDC) system is standard.
The Nissan 370Z Roadster's list of standard safety features includes the Nissan Advanced Air Bag System (AABS) with dual-stage supplemental front air bags with seat belt and occupant classification sensors; front seat-mounted side impact supplemental air bags; door-mounted curtain air bags; and seat belts with pretensioners and load limiters.
