The 2012 Nissan GT-R’s advanced VR38DETT 3.8-liter twin turbo V6 now produces 530 horsepower (versus the previous 485 horsepower) and 448 lb-ft of torque (versus the previous 434 lb-ft) – a result of modifying the boost pressure of the turbocharger, valve timing and air fuel ratio, and through reducing intake air resistance by enlarging the inlet pipe diameter. In addition, exhaust air resistance was reduced through use of an enlarged section of exhaust pipe.
GT-R’s already impressive aerodynamic performance has been improved for 2012 with downforce increased by about 10% and the coefficient of drag reduced to 0.26 (from 0.27). Enlarged fascia and grille openings also help reduce air resistance inside the engine compartment. The volume of air that passes through the radiator and cools the front brakes is also increased. These aerodynamic and engine improvements have also resulted in improved fuel economy estimates 16 city and 23 highway (verses 15/21 in previous years).
