nissan gt-r
The Nissan GT-R is a sports car produced by Nissan released in Japan on December 6, 2007, the United States on July 4, 2008, and the rest of the world in March 2009.
Nissan introduced the GT-R SpecV on January 7, 2009 at the 2009 Tokyo Auto Salon. Exterior changes from the base GT-R consist of a carbon fiber rear spoiler, grille, and brake ducts, along with an exclusive Ultimate Black Opal paint job. Interior changes include a set of carbon fiber Recaro front seats with the rear seats being completely removed. Carbon fiber covers the center storage box, instrument panel, and replaces the majority of the interior trim.
The GT-R SpecV is powered by the standard twin-turbo 3,799 cc (3.8 L; 231.8 cu in) V6 with no increase in horsepower. A new high gear boost controller that allows a temporary increase in boost pressure to the IHI twin turbochargers, now larger than those on the standard GT-R, should deliver more torque in mid to high-range revs. Other mechanical changes include a titanium exhaust, reworked suspension, carbon ceramic brakes, and 20-inch (510 mm) NISMOwheels. Overall weight is decreased by 132 lb (60 kg) over the standard GT-R.
Japan sales began on February 2, 2009 at seven pre-selected dealers who are staffed by mechanics with special GT-R SpecV training and are knowledgeable of racing circuit driving. Pricing is set at ¥15,750,000 (over US$160,000). Nissan has yet to announce any plans to sell the Spec V in the USA.
In Auto Express testing the SpecV posted a 0-60 mph time of 3.2 seconds, pulled 1.12 g on the skidpad and 74.7 mph in the slalom. An earlier tested Corvette ZR1 (2011) resulted in an identical slalom speed but a lower 1.06 g on the skidpad

Top Speed 193 mph (311 km/h)
The Nissan GT-R is powered by the VR38DETT engine, a 3,799 cc (3.8 L; 231.8 cu in) DOHC V6 with plasma transferred wire arc sprayed bores. Two parallel Ishikawajima-Harima Heavy Industries (IHI) turbochargers provide forced induction. Production vehicles produce a manufacturer-claimed engine output of 485 PS (357 kW; 478 hp) at 6400 rpm and 434 lb·ft (588 N·m) at 3200-5200 rpm. 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 six-speed BorgWarner designed dual clutch semi-automatic transmission built by Aichi Machine Industry 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) to aid in stability. Three shift modes can also be selected for various conditions.
Nissan claims the GT-R can reach a top speed of 193 mph (311 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 3.8 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 launching the car at around 4500 rpm. However, Nissan's director of product planning John Wiener clearly stated in an interview with Jay Leno that "we (Nissan) actually offer a 'launch mode'". 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. 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. The new facelifted GT-R however now has a launch mode, which Nissan calls "R-Mode Start", and is activated by setting the Transmission and VDC to "R" mode (the Suspension settings can be left in normal mode), holding the brakes, then the throttle, and finally releasing the brakes. The engine speed is now held at 4,000 rpm in this mode, and it no longer voids the warranty. However, the system allows a maximum of 4 consecutive hard launches before locking itself out, after which it can be unlocked by driving normally for 1.5 miles. Tests by Edmund's Inside Line have shown the 2012 GT-R to achieve 0-60 mph in 2.9 seconds with R-Mode Start activated and did the 1/4 mile in 11.2 seconds going 122.7 MPH.
The GT-R was used as the official safety car for both the 2008 Japanese Super GT, and the 2009 Australian V8 Supercars series before a dispute over alcohol advertising led to the arrangement being discontinued after four rounds.
