Car and Driver

Nissan insists this engine is all-new and unrelated to the VQ sixes that propel the Z car, Infiniti Gs, and others, which is interesting since the bore (95.5 millimeters) is exactly the same. The new six is force-fed by a pair of IHI turbos via an air-to-air intercooler. Max boost is 10.2 psi.

This is the first V-6 in the modern GT-R series (the three preceding cars employed inline-sixes), and we think it won’t disappoint anyone except maybe tuners. We say that because the Nissan development team proudly claims it has made the car’s ECU tamper-proof. The objective seems to be to portray the engine as environmentally friendly. Yeah, right. And with a little training, tigers make terrific house pets. But tuners always manage to crack the codes, so for those GT-R owners who will inevitably want more, hang in there.

Power finds its way to the ground via a rear-mounted Aichi Kikai six-speed dual-clutch automated manual transaxle with triple cone synchros. The rear diff is a mechanical limited slip; the front is operated by an electronically controlled clutch.
