ENGINE

 

Under the hood, the Nissan GT-R features an all-new 3.8-litre twin turbo V6 “VR38″ engine, featuring plasma-sprayed bores and a special twin-turbo exhaust manifold system. A secondary air management system enables the newly designed powerplant to provide approximately 40kg/m of torque during ordinary low-rev driving, which gives an optimum air-fuel ratio for around-town efficiency and helps the Nissan GT-R meet ultra-low emission vehicle (U-LEV) standards in Japan.

The Nissan GT-R’s new engine produces 480PS (353kW) at 6400rpm and maximum torque of 60kgm (588Nm) from 3200 to 5200rpm. Putting the power to the ground is an all-new GR6-type dual clutch transmission, with paddle shifting and a Borg Warner six-plate dual clutch for direct control.

• VR-series twin-turbocharged 3.8-liter V6.
• 480 hp @ 6,800 rpm. 430 lb-ft torque @ 3,200–5,200 rpm.
• Dual overhead camshafts with variable intake-valve timing.
• Cast aluminum cylinder block with high-endurance/low-friction plasma-sprayed bores.
• IHI twin turbochargers, one per cylinder bank.
• Pressurized lubrication system with thermostatically controlled cooling.

• Engine designation: VR38DETT (Twin Turbocharged 3.8-liter V6)

• 60 degree V6 configuration

• Redline: 7000rpm

• Power: 473 hp (6400rpm)

• Torque: 433 ft-lb (3200-5200rpm (flat torque curve!)

• The engine performance of the 3 trims is the same

• Twin turbos with integrated exhaust manifolds
• Boost pressure: 10.2 psi

 

DRIVETRAIN:

The all-new Nissan GT-R uses a Premium Midship package, an all-new, more advanced version Front Midship (FM) package utilized on other Nissan vehicles. This new package enables the use of the world’s first application of an independent transaxle 4WD system. The transaxle’s layout places the dual-clutch transmission, transfer case and final drive at the rear of the vehicle (instead of the usual front location), which enables vehicle weight to be evenly distributed throughout the car. This gives the Nissan GT-R a superb front-to-rear weight balance, while enhancing leg and foot space and allowing for an optimal pedal layout.

• ATTESA ET-S All-Wheel Drive (AWD) with independent rear-mounted transaxle integrating transmission, differential and AWD transfer case.
• Rigid, lightweight carbon-composite driveshaft between engine and transaxle.
• Electronic traction control plus 1.5-way mechanically locking rear differential.
• Vehicle Dynamics Control (VDC-R) with three driver-selectable settings: Normal (for daily driving, controls brakes and engine output), R-Mode (for ultimate performance, utilizes AWD torque distribution for additional vehicle stability) and Off (driver does not want the help of the system).
• Hill Start Assist prevents rollback when starting on an incline.
DisclaimerVDC-R cannot prevent accidents due to abrupt steering, carelessness, or dangerous driving techniques. Always drive safely.

• There is no Manual transmission option
• Twin clutch six-speed paddle shifted automatic (one clutch handles 1/3/5, the other handles 2/4/6)

• BorgWarner triple-cone synchronizers on all gears

• Shifts take 0.2 seconds
• Carbon fiber driveshaft
• Torque split front to rear is 50/50 under 25mph, then shifts to 40/60 under normal conditions, then 2/98 under hard acceleration
• Unlike versions of this system in other Nissan vehicles—the Infiniti G35x, for example—the GT-R setup employs a yaw sensor and is capable of instantly transferring torque from side to side, as well as fore-and-aft, as conditions dictate.
• Gearchange speed is adjustablefor taste and conditions
• Electronical traction control system.

TRANSMISSION:

• 6-speed Dual Clutch Transmission with three driver-selectable modes: Normal (for maximum smoothness and efficiency), Snow (for gentler starting and shifting on slippery surfaces), and R mode (for maximum performance with fastest shifts).
• Fully automatic shifting or full sequential manual control via gearshift or steering wheel-mounted paddle shifters.
• Dual clutch design changes gears in less than 0.5 second (0.2 second in R mode).
• Downshift Rev Matching (DRM).
• Predictive pre-shift control (in R mode) based on throttle position, vehicle speed, braking and other information.
