[TMS] Nissan GT-R with Max Output of 480PS: Price starts from ¥7.77 Mil
Nissan Motor Co Ltd unveiled Oct 24, 2007 its brand-new "GT-R" at the 40th Tokyo Motor Show. The model, mounted with a 3.8-L V6 twin-turbo engine, features maximum output of 353kW (480PS) and maximum torque of 588N·m.
It will be released in the Japanese market Dec 6, 2007 at a price of ¥7,770,000 (US$67,973) to ¥8,347,500.
The model, developed under the concept of "multi-performance super car," is designed as a high-performance car that can be driven on dry roads as well as wet or snow-covered road. Nissan defines a super car as "a car with a power-weight ratio of less than 4kg/PS that can be driven on public roads at 300km/h and the Nurburgring circuit within the lap time of eight minutes."
A multi-performance super car satisfies those requirements and at the same time can be driven under every imaginable condition, according to the company.
The model, designed with priority on kinematic performance, adopts a transaxle system in which a dual-clutch 6-speed AMT (Automatic Manual Transmission) is mounted in front of rear wheels. The transaxle is shaped flat so as to keep the center of gravity low and improve turning stability.
The model is mounted with a 3.8-L engine that features a closed deck structure called "VR38DETT." Its bore bitch is the same as that of a VQ engine, but the model employs a cast iron block without a liner, equipped with a water jacket between bores. The oil system is not a dry sump, but is equipped with a scavenging pump for cooling the turbine.
The engine power is transmitted to the transaxle in front of rear wheels through a propeller shaft made of CFRP (carbon fiber reinforced plastic). Then the power is transmitted from two pairs of wet clutches to a pair of hollow axes, then through the output shaft to the rear differential.
Front wheels are driven by the power transmitted to the front differential through a shaft that extends from an electronically-controlled coupling integrated into the front part of the transaxle. Open differential is used for front wheels, while 1.5-way LSD (limited slip differential) is used for rear wheels.
The transmission is designed by Nissan and manufactured by Aichi Machine Industry Co Ltd. The wet clutch is manufactured by BorgWarner of the US, which supplies to Mitsubishi Motors Corp for its "Lanser" and Volkswagen AG for its "DSG."
The triple cone synchoro gear is employed in the model. The transmission can be switched between manual mode and automatic mode. In the manual mode, the response is so fast that the drive force of rear wheels changes in only 0.2 seconds after operation of the paddle beside the steering wheel.
The exclusively designed body has a unique structure that features a lowered and flat floor, which improves downforce in highway driving. The side members, usually located under the floor, prevent the lower surface of the floor from being flat. However in this model, the side members are located above the floor to lower the floor surface.
If the driver wants to experience the performance of 300km/h in Japan, the speed limiter will be canceled at locations such as Fuji Speedway registered in advance in the navigation system. In addition, the multi-function meter, displayed by switching over the navigation screen, displays information such as acceleration ratio and front/rear G, which allows the driver to review his/her driving later.
The vehicle weight is 1,740kg and the fuel consumption at 10·15 mode is 8.2km/L. The riding capacity is four.
