Nissan GT-R concept

Nissan GT-R by Have Fun SVO.
The production version of the GT-R debuted at the 2007 Tokyo Motor Show, launching in the Japanese market on December 6, 2007. The U.S. official launch was 7 months later on July 07, 2008. Universal Nissan in Los Angeles provided a customer with the delivery of a new GT-R, fresh from the production line at 12:01 a.m., on July 7, 2008. The Canadian launch was also in July 2008. Europe became the third consumer market, where it launched late in the year. The large disparity in initial marketing between these regional releases is due to Nissan having to build GT-R performance centers where the car is serviced. Also the engine and rear-mounted dual-clutch gearbox are built by hand, thus limiting production to around 1000 cars a month.


Specifications

The Nissan GT-R is powered by the VR38DETT engine, a 3,799 cc (3.8 L; 231.8 cu in) DOHC V6. Two parallel Ishikawajima-Harima Heavy Industries (IHI) turbochargers provide forced induction. Production vehicles produce a manufacturer-claimed engine output of 480 bhp (360 kW) at 6400 rpm and 434 lb·ft (588 N·m) at 3200-5200 rpm. According to independent dynamometer tests, the GT-R produces 416 hp (310 kW) to 475 hp (354 kW) and 414 lb·ft (561 N·m) to 457 lb·ft (620 N·m) at the wheels. The engine also meets California Air Resources Board Ultra Low Emission Vehicle (ULEV) standards. A curb weight of 1,730 kg (3,800 lb) or 1,736 kg (3,830 lb) with side curtain airbags is achieved using a jig welded steel chassis with aluminum used for the hood, trunk, and doors. A rear mounted 6 speed dual clutch semi-automatic transmission is used in conjunction with the ATTESA E-TS system to provide power to all four wheels and along with Nissan's Vehicle Dynamics Control (VDC-R) aids in stability. Three shift modes can also be selected for various conditions. The drag coefficient is 0.27.

Performance

Nissan claims the GT-R can reach a top speed of 192 mph (309 km/h), Motor Trend recorded a top speed of 195.0 mph (313.8 km/h). It has been tested to achieve 0-60 mph (97 km/h) times as low as 3.2 seconds with "launch control" and 3.9 seconds without (improved to 3.5 seconds in models produced since March 2009). Nissan's chief vehicle engineer Kazutoshi Mizuno has indicated that he has never used the term "launch control", which refers to the act of turning off vehicle dynamic control (VDC) and launch the car at around 4500 rpm. The GT-R user's manual states that turning off the VDC is only meant for escaping low-traction situations such as mud or snow, and that damage to the transmission is not covered under warranty if the VDC is used in other ways. It reportedly costs $20,000 USD to replace a damaged transmission outside of warranty. Nissan has re-programmed the 2010 model year GT-R to reduce the engine speed at launch to around 3,000 to 3,500 rpm with VDC enabled, which is meant to improve acceleration times. The new programming was also installed on old 2009 vehicles still in Nissan's inventory, and is available for existing 2009 vehicles.

Car and Driver achieved a standing quarter-mile time of 11.5 s at 200 km/h (120 mph). Evo magazine achieved a 0-100-0 mph time of 13.9 seconds. Autocar achieved a 0-100 mph (160 km/h) time of 8.5 seconds.

With a manufacturer claimed lap time of 7:26.7 on the base model's Dunlop tires and previously 7:29 min on standard Japanese market tires, the GT-R is currently one of the fastest production cars to lap the Nürburgring circuit, although Porsche accused Nissan of falsifying those claims in September 2008. Porsche claims to have conducted their own test of the GT-R using no modifications and stock tires and achieved a best time of 7:54. Nissan officially disputed Porsche's claim in October 2008. The German magazine sport auto achieved a time of 7:38 minutes on the Nürburgring in a test with a standard GTR when being driven by Horst von Sauma. A test by Drivers Republic of a GT-R and GT2 in stock form resulted in times of 7:55 for the GT-R and 7:49 for the GT2 respectively, though this test was conducted in partially damp conditions.

Autocar released a video comparison of the GT-R with the Porsche 911 GT3 and BMW M3. Driven by test driver Chris Harris the GT-R was the fastest of the three. Evo tested the GT-R alongside the 911 GT3 at the Bedford Autodrome circuit, the GT-R ran a 1:21.7 lap time compared to GT3's 1:22.6 time. Car and Driver compared the GT-R on Reno-Fernley Raceway with the Porsche 911 Turbo and BMW M3, the GT-R's lap time of 1:26.7 made it the fastest on the track. Road & Track was able to achieve quick lap times with the car on Buttonwillow Raceway, clocking in at 1:56.9 just over 5 seconds faster than the Chevrolet Corvette C6 Z06 and Porsche 911 Turbo. On Willow Springs International Motorsports Park, Edmunds was able to achieve lap times of 1:25.09 compared to the Corvette ZR1's time of 1:23.87. In an earlier Edmunds 6-way test which included the Audi R8 on both the Streets of Willow and an improvised mountain road, the GT-R was quickest. On the Las Vegas Motor Speedway infield road course, Motor Trend were able to achieve lap times with the GT-R that were almost as fast as the Ferrari 599 GTB Fiorano and Porsche 911 GT2 and 3 seconds slower than a Chevrolet Corvette ZR1. The GT-R currently holds a lap time of 1:19.7 around the Top Gear Test Track, equaling that of the Ferrari 430 Scuderia. On Top Gear Australia's test track the GT-R posted a lap time of 1:07.06, putting it in second place 0.14 seconds behind the Porsche 997 GT2. Top Gear laps are conducted from a standing start.
