2020 Nissan GT-R Nismo Sports Introduce https://youtu.be/Bsf3mi_Liz0

The 2020 Nissan GT-R NISMO is a case in point.
This latest GT-R NISMO, the third R35 model to carry the storied NISMO badge, is a case study in kaizen, the Japanese art of continuous improvement. And for 2020, the ultimate performance version of Nissan's ultimate performance car gets a swarm of changes that redefine the term "detail."

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.
The engine makes the same 600 hp at 6,800 rpm and 486 lb-ft from 3,600 rpm to 5,600 rpm as in the previous GT-R NISMO. It just feels livelier doing it. The shift control algorithm for the six-speed dual-clutch transmission has been rewritten to capitalize on the improved throttle response when in automatic mode and to deliver faster downshifts in both auto and manual modes to keep the car better balanced on corner entry.

Extensive use of carbon-fiber panels has helped trim nearly 23 pounds from the body structure. The carbon front and rear bumpers and new front fenders—with Porsche 911 GT3 RS-style vents over the wheel arches—together account for 10 pounds of that. The hood, with integrated NACA ducts, is also carbon fiber, saving 4.4 pounds, and a beautifully rendered, handmade carbon-fiber roof panel saves a further 8.8 pounds. Those louvered front fenders not only look good but also help increase front downforce by just over 15 pounds without creating additional drag.
The bulk of the 66-pound reduction in weight over the previous GT-R NISMO is down to a new brake package. Massive carbon-ceramic rotors—16.1 inches up front and 15.3 inches at the rear, clamped respectively by six- and four-piston Brembo calipers dipped in yellow paint that can withstand temperatures of 1,000 degrees C without discoloring—are now standard equipment on the GT-R NISMO. The new brake setup not only delivers a 36-pound reduction in total unsprung weight but also increased durability and fade-free performance under extreme braking conditions. With fewer pounds to manage, the Bilstein DampTronic shocks now have a 5 percent softer compression rate and 20 percent softer rebound rate.

One weight-saving feature U.S. and Canadian 2020 GT-R NISMO buyers won't get, however: the new, heavily sculpted Recaro seats, which are each 3 pounds lighter than those in the previous model. Blame our unique airbag laws.

The new 20-inch, nine-spoke Rays forged alloy wheels are each 0.2 pound lighter than the previous car's wheels and are shod with new Dunlop SP Sport Maxx GT600 tires—255/40 front and 285/35 rear—specially designed to eke more cornering grip and stability out of the big Nissan. The overall contact patch has been increased 11 percent, courtesy of a redesigned tread pattern—the outside quarter of the front tire has no longitudinal grooving—plus a more rounded shoulder that provides grip even as the tire rolls under the rim during extreme cornering. A revised production process reduces waste as the tire comes out of the mold.

To sum up, the 2020 GT-R NISMO is slightly lighter, is slightly more responsive, and has slightly more grip than the previous model. But the benefits are measurable, Tamura insists. He says that from a standing start, the 2020 GT-R NISMO will be 8 feet ahead by the time it hits 50 mph. The 5 percent improvement in cornering force and better brake performance mean a 5-second-quicker lap time at the Nürburgring Nordschleife.
