The 370Z is available in coupe and roadster (convertible) body styles. All trims other than the NISMO come with the same 332-horsepower 3.7L V6 and a choice of 6-speed manual or 7-speed automatic transmissions sending power to the rear wheels. The NISMO coupe adds power with its 350-horsepower 3.7L V6. The V6 employs Variable Valve Event and Lift Control--tech magic that makes sure the engine can stay smooth and efficient while providing strong performance. The EPA combined fuel economy is 22 mpg, with 26mpg on the highway. The 370Z has been tested to accelerate to 60 mph in around five seconds. Both available transmissions are designed to maximize driving enjoyment. Nissan's "SynchroRev Match" in the 6-speed manual automatically matches revs to the next gear to make up-shifting smooth and down-shifting a blast. The 7-speed automatic gets a comparable feature that matches revs to help reduce the jolt that is otherwise felt on a forced downshift. The automatic comes with steering-wheel paddle-shifters. Underneath, the 370Z's suspension uses double wishbones in front and a multi-link setup in back, all kept under close control with stabilizer bars and sport-tuned shocks. Grip is tremendous and balanced thanks to standard 18-inch aluminum-alloy wheels with staggered-width summer performance tires. An optional Sport Package brings 19-inch custom forged alloy wheels and even wider tires, along with larger Nissan Sport Brakes, 4-piston front calipers and a viscous limited-slip differential. All 370Z models feature 4-wheel anti-lock brakes with brake assist, along with electronic brake-force distribution. Nissan Advanced Air Bag System with front seat-mounted side airbags and roof-mounted side-curtain bags are also standard. The clever speed-sensitive power steering is designed to reduce vibrations and major shocks while still transmitting road feel to the driver. The 370Z roadster features a black-cloth convertible soft top with a softer fabric inner liner that helps insulate the interior and reduce noise. The power soft top takes about 20 seconds to fully open or close. When the top is down, it stows away under a hard tonneau cover. There's also a pop-up glass wind deflector between the fixed headrest bars; it serves to help reduce turbulence at high speed. The Heritage Edition honors the Z's 50-year historic journey. Available in black or yellow paint, it is highlighted by black wheels, black mirror caps and custom striping. The heritage design continues throughout the interior with stylish yellow accents. The Sport Touring models add a host of extras, including heated-and-cooled leather power seats, a Bluetooth hands-free system, a garage door opener, aluminum pedals and an 8-speaker Bose audio system. An available Navigation Package will help owners navigate the roads ahead. This model is only available in automatic transmission. The NISMO 370Z coupe features an up-rated version of the same 3.7L V6, now delivering 350 horsepower as well as a NISMO-tuned dual exhaust. The car also includes race-inspired design cues, including NISMO aerodynamic body designs, an even firmer suspension, a premium stereo and special 19-inch forged alloy wheels on Dunlop high-performance tires.
