The Nissan GT-R is a 2-door 2+2 sports car produced by Nissan and unveiled in 2007. It is the successor to the Nissan Skyline GT-R although it is no longer part of the Skyline range. Now the Nissan Skyline and the Nissan GT-R are separated. The Nissan GT-R is powered by the VR38DETT V6 engine, a 3,800 cc (3.8 L; 231.9 cu in) DOHC V6 with plasma transferred wire arc sprayed cylinder bores. Two parallel Ishikawajima-Harima Heavy Industries (IHI) turbochargers provide forced induction. Models manufactured between 2007 and 2010 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.
