2015 Nissan GT-R - What's New?

While the upcoming GT-R NISMO features a range of unique engine modifications, the 2015 GT-R Premium and Black Edition once again are powered by a potent 545-horsepower advanced VR38DETT 3.8-liter twin turbo V6. Torque is rated at 463 lb-ft.
Each engine is hand-assembled from beginning to end in a special clean room by specially trained technicians, a process similar to racing powerplant construction. An aluminum plate is added to the front of each engine showing the name of the "Takumi" engine craftsman.
The engine features innovative plasma-sprayed bores (versus cast iron liners) for reduced friction, lighter weight, enhanced cooling, power output and fuel efficiency; a symmetrical independent intake and exhaust manifold system featuring twin high-performance IHI turbochargers; a secondary air management system for improved cold-start emissions performance; a thermostatically controlled oil-cooling system; an oil scavenger pump to maintain oil flowing to the turbochargers; and a lateral wet and dry sump oiling system. The GT-R's fuel economy is again rated at 16 mpg city and 23 mpg highway.
The VR38DETT V6 is backed by an advanced paddle-shifted sequential 6-speed dual clutch transmission, which can be driver selected to shift at race car-like speeds. The sequential-shifting transaxle features separate wet clutches for the odd (1,3,5) and even (2,4,6) gears and pre-selects the next highest and next lowest gear for quick shifts. It also features Hill Start Assist for easy starts on uphill inclines. High performance differential oil, used in GT-R motorsports competition, is standard.
The Nissan GT-R's unique Premium Midship platform, created expressly for use with the GT-R, enables the use of the world's first independent rear transaxle ATTESA E-TS all-wheel drive system, which optimizes weight distribution and handling capability. The rear drive-biased system can vary torque split from 0:100 to 50:50 depending on speed, lateral acceleration, steering angles, tire slip, road surface and yaw rate. Of note is a special GT-R-specific yaw-rate feedback control, which measures the differences between the target yaw rate calculated from steering angle and actual yaw rate detected by the yaw-rate sensor and G sensor to adjust torque bias.
The Premium Midship Platform layout places the transmission, transfer case and final drive at the rear of the vehicle, without the use of traditional torque tubes, allowing the suspension to operate independently and optimizing tire grip at each corner.
Contributing to overall vehicle balance and low center of gravity, the unique offset input and reaction shaft design of the rear transaxle enables a shorter design profile versus a typical manual transmission, moving the concentration of powertrain weight lower in the vehicle.
