We test out the updated sports car  Let's start under the hood. The legendary VR38DETT V-6 has been given two new turbochargers, lifted straight from Nissan's GT3 GT-R race car. These feature 10-vane turbines instead the 11-vane items used previously, and each vane is 0.3mm thinner, reducing the mass of each turbine by 14.5 percent. That means a 24 percent reduction in inertia, which, Tamura says, translates to a 20 percent improvement in engine response from zero to wide-open throttle.
