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 474 bhp (353 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 six-speedBorgWarner 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 GT-R has a drag coefficient of 0.27.

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) NISMO wheels. 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 test of the Corvette ZR1 resulted in an identical slalom speed and a lower 1.06 g on the skidpad.
Nissan chief creative officer, Shirō Nakamura, has likened the new GT-R to the eponymous giant robots of the Gundam series. Nakamura stated: "The GT-R is unique because it is not simply a copy of a European-designed supercar; it had to really reflect Japanese culture."
Nakamura noted that the GT-R's square lines and vents were influenced by Gundam robots. Nissan's American designers sculpted the rear three quarters of the vehicle, while their European designers sculpted the roofline.
Polyphony Digital, creators of the Gran Turismo series of racing video games, were themselves involved in the development of the GT-R, having been contracted to design the GT-R's multifunction display.
