Nissan 370Z Roadster
From Nissan press: Less than a year after the introduction of the all-new 2009 Nissan 370Z Coupe – a vehicle that reset the bar for affordable sports car design and performance – comes its dramatic new stablemate, the 2010 Nissan 370Z Roadster. The seductively styled Z® Roadster offers everything the hardtop Z® Coupe does – and more. As in more classic open-air sports car driving excitement. More sun, moon and stars. And more refinement than any Z® convertible that has ever come before – including a standard automatic latching power top and Nissan Intelligent Key™.
The 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.
The new Z® Roaster is offered in two well-equipped models – 370Z Roadster and the 370Z Touring Roadster.
Roadster or Coupe, the new Z®s 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).
Along with its larger displacement, 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.
