The 2020 GT-R NISMO is about total balance. New, race-proven turbochargers, improved gearbox shift control, lighter components, reduced overall mass and upgrades to the brakes, wheels and tires contribute to a 2.5-second reduction in lap time around Nissan’s development track, not to mention an improvement of the GT-R’s inherent high speed stability, even at speeds of up to 186 mph (300 kph). Here’s how Nissan achieved this remarkable improvement.
Racing improves the breed, and that is very much the case with the 2020 GT-R NISMO. Like in racing, precision is the key to performance. Each VR38DETT is hand-assembled from beginning to end in a special clean room by master technicians known as takumi. This elite few assemble the complex powerplant with the passion and precision of a true craftsman. Just as a great artist signs their work, so do the takumi, with a special aluminum name plate on the front of each engine that meets their standard.
The car’s new turbochargers are the same ones currently used on the GT3 racecar version of the GT-R. These employ a 10-vane turbine wheel (one fewer vane than the current model), where the vanes are 0.3 millimeters thinner. This accounts for a 14.5% reduction in mass, and therefore inertia (24%), allowing for an increase in transient response. Consequently, having one less vane would reduce flow rate, so to counteract, a new back plate was created to prevent exhaust gases from flowing behind the turbine blades, drastically improving flow efficiency. Through the latest fluid and stress analysis, special attention was given to the actual design and profile of the vanes. Their new shape optimizes efficiency with exhaust gases to boost flow rate resulting in improved boost response and acceleration as well as in gear “pickup” in any situation.
The diagram below gives an idea of how response improves by comparing the car with the previous GT-R NISMO, accelerating from 110 kph and 4,000 rpm in fourth gear (manual mode). The response is immediate and instantly felt. The following diagram shows engine response improvement of 20% as the driver increases throttle pressure, from 0% opening to wide open throttle. While power remains unchanged at 441kW (600ps), the result is a sharper feeling that further enhances the overall character of the hand-assembled VR38DETT.
A revised titanium exhaust system now has a more emphatic – yet not intrusive – tone coming through to the cabin. Handcrafted burnished tips are a signature touch of the lightweight system.
When in R-mode, the improved 6-speed dual-clutch transmission now shifts gears more aggressively and intuitively thanks to a new algorithm for the adaptive shift control (ASC). This selects the best gear for any driving scenario and can especially be felt during braking and approach into a corner, where the driveline feels more precise with faster downshift reactions to help reduce understeer on entry.
