The 2018 GT-R’s award-winning 3.8-liter 24-valve twin-turbocharged V6 engine – each unit handcrafted by its own Takumi technician – delivers 565 horsepower at 6800 rpm and 467 lb-ft of torque, thanks in part to an ignition-timing system controlled at each individual cylinder – technology utilized on the potent GT-R NISMO. Like with the GT-R NISMO, by more precisely controlling ignition timing at each cylinder, engine knock is significantly reduced while concurrently enhancing environmental performance through a cleaner, more efficient fuel burn.

Dubbed the “VR38DETT,” the engine features plasma-sprayed bores (versus cast iron liners) for reduced friction and weight, enhanced cooling, superior power output and increased fuel efficiency. It also boasts a symmetrical independent intake and exhaust manifold system with twin high-performance 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.

Each engine is hand-assembled from beginning to end in a special clean room by highly skilled technicians. An aluminum plate is added to the front of each engine showing the name of the Takumi engine craftsman.

Nissan GT-R Premium, Track Edition and NISMO models feature a titanium exhaust system that better manages the high temperatures of the exhaust gases from the engine. The system includes a duct on the vehicle’s undertray just forward of the muffler, which guides air into the rear diffuser section to help cool the muffler and evacuate hot air.

The transmission shift-management control of the sequential 6-speed dual clutch transmission has been updated for better refinement and performance in a variety of driving situations. For example, when the vehicle begins moving from a standstill at a slow rate of acceleration, the gear shift change from 1st to 2nd gear is now much smoother than before.

Engine power is transferred to all four of the GT-R’s wheels via an independent rear transaxle, the ATTESA E-TS all-wheel-drive system. During normal driving, the GT-R behaves like a rear-drive vehicle, with the torque split set at 0:100, but it can be automatically diverted up to 50:50 depending on speed, lateral acceleration, steering angle, tire slip, road surface and yaw rate. A special GT-R-specific yaw-rate feedback control measures the differences between the target yaw rate calculated from the steering angle and actual yaw rate detected by the yaw-rate sensor and G sensor, and adjusts the torque bias accordingly.

The GT-R’s 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 while optimizing weight distribution and maximizing tire grip at each corner.

The GT-R’s Bilstein® DampTronic driver-adjustable shock-absorber system – which utilizes information from multiple vehicle systems to provide appropriate damping forces and high level of control for a variety of driving situations – includes a valve housing system that reduces resistance losses. Also, rigid attachment points for the suspension enhance cornering stability and turning response by allowing all of the wheels to be placed under even a greater load while maintaining optimal contact with the road surface.

The DampTronic system features three driver selectable settings: Normal; Comfort, for maximum suspension compliance; or R. The same three-stage adjustability is also available for the VDC system and transmission shift operation. The “R” and “Comfort” settings offer the driver enhanced sportiness and a smoother ride quality. Because of the increase in structural rigidity, the “R” mode enables the vehicle to achieve the same yaw rate with reduced steering angle for a crisper, more communicative steering response, while the “Comfort” suspension setting produces less vertical G-loading in testing when compared to the “Normal” suspension setting. Stylish 20-inch 15-spoke forged alloy wheels by RAYS® offer light weight, strength and rigidity.

The 2018 GT-R’s steering system – a speed-sensitive power rack-and-pinion design with aluminum steering rack, four-point mounting and stiff insulators – possesses sharp response during spirited driving, with reduced effort for around-the-town commutes and exceptional feedback on the open highway.

Stopping power is provided by Brembo® monoblock six-piston front and four-piston rear calipers with 15.35-inch front and 15.0-inch rear Brembo® full-floating, cross-drilled two-piece rotors and low-steel, high-stiffness brake pads that minimize fade and provide intense stopping performance. The calipers utilize race car-style radial mounting to minimize caliper flex during extreme braking.
