With a Twin Turbo V6 producing an earth-shaking 545 horsepower, it’s easy to overlook everything else GT-R® has to offer—which is a lot. For 2015, that includes a new recalibrated suspension that reduces load fluctuation between the four wheels, and keeps your wheels tight on the road for a smoother, more sophisticated ride. We’ve also added advanced headlights that adjust their illumination pattern based on your driving speed, and an all-new interior option with pale ivory semi-aniline seats, and contrasting hand-stitched details.
From start to finish, each GT-R engine is handcrafted by its own master engine-builder in a climate-controlled "clean room." Each twin-turbo V6 is precisely assembled from lightweight, highly durable aluminum and magnesium parts. It takes the exacting standards of the plant's most talented and devoted engine builders to produce the engine that has redefined what a supercar can be.
