BERLIN – Nissan just lately invited members of the media to EuroSpeedway Lausitz, a race observe in Germany and the encircling environs, to perform one purpose: expertise the precision engineering of the brand new 2020 GT-R NISMO within the area that highlights it greatest.
There are various unbelievable driving places around the globe, however solely in Germany does a driver discover the mixture of high-speed street and observe experiences that actually showcases the GT-R NISMO’s “absolute complete racing efficiency.”
The 2020 Nissan GT-R NISMO is the fruits of two of Nissan’s most vital nameplates: GT-R – representing 50 years of historical past, pedigree, success in racing and a worldwide fan following – and NISMO, NISsan MOtorsports Worldwide Co., Nissan’s in-house tuning arm that pursues efficiency at a maniacal stage by perfecting the smallest of particulars. True to what NISMO stands for, the 2020 GT-R NISMO is a extra excessive, track-oriented model of the GT-R that has matured by way of rigorous refinements, and turn into sharper and extra rewarding as a road automotive.
The 2020 GT-R NISMO is about complete steadiness. New, race-proven turbochargers, improved gearbox shift management, lighter elements, diminished general mass and upgrades to the brakes, wheels and tires contribute to a 2.5-second discount in lap time round Nissan’s growth observe, to not point out an enchancment of the GT-R’s inherent excessive pace stability, even at speeds of as much as 186 mph (300 kph). Here is how Nissan achieved this exceptional enchancment.
Constructing on the kaizen mindset
The pursuit of perfection requires persistence. The fixed have to evolve and fine-tune – that is kaizen. Kaizen is on the coronary heart of the GT-R NISMO, a crew huge mindset that has pushed the women and men behind this automotive to problem themselves every step of the way in which. They present an inherent curiosity and “what-if” mentality when revisiting each minute element. Small enhancements could not appear vital in isolation, however it’s once they’re mixed as a complete distinction turns into perceptible. That is when a automotive’s character grows; it isn’t all about numbers and efficiency however the holistic impact – how the GT-R NISMO turns into an extension of a driver’s physique and thoughts because the car carves a line by way of a favourite street or race observe.
Led by Tamura, executed by the crew
Chief Product Specialist Hiroshi Tamura – often called “Mr. GT-R” – has been at Nissan for greater than thirty years. Devoted to evolving and bettering the GT-R, he has been a part of virtually each step of the mannequin’s evolution.
His love for Nissan’s most legendary sports activities automotive was sparked early. At age 10, he witnessed Takahashi Kunimitsu take his blue and white 2000 Skyline GT-R racecar to an epic end at a really moist Fuji Speedway, beating sturdy rivals like Mazda and its RX3. Tamura knew from that second that he wished to not simply watch the GT-R but in addition be a part of its success.
Right this moment, Tamura ensures the GT-R continues to evolve yr in and yr out, staying atop a rising discipline of opponents, together with the costliest crop of supercars – and in some circumstances hypercars.
GT3 turbos for the VR38DETT
Racing improves the breed, and that’s very a lot the case with the 2020 GT-R NISMO. Like in racing, precision is the important thing to efficiency. Every VR38DETT is hand-assembled from starting to finish in a particular clear room by grasp technicians often called takumi. This elite few assemble the complicated powerplant with the eagerness and precision of a real craftsman. Simply as an incredible artist indicators their work, so do the takumi, with a particular aluminum title plate on the entrance of every engine that meets their commonplace.
The automotive’s new turbochargers are the identical ones at present used on the GT3 racecar model of the GT-R. These make use of a 10-vane turbine wheel (one fewer vane than the present mannequin), the place the vanes are zero.Three millimeters thinner. This accounts for a 14.5% discount in mass, and subsequently inertia (24%), permitting for a rise in transient response. Consequently, having one much less vane would scale back circulation fee, so to counteract, a brand new again plate was created to forestall exhaust gases from flowing behind the turbine blades, drastically bettering circulation effectivity. By way of the newest fluid and stress evaluation, particular consideration was given to the precise design and profile of the vanes. Their new form optimizes effectivity with exhaust gases to spice up circulation fee leading to improved enhance response and acceleration in addition to in gear “pickup” in any scenario.
The diagram beneath provides an thought of how response improves by evaluating the automotive with the earlier GT-R NISMO, accelerating from 110 kph and Four,000 rpm in fourth gear (handbook mode). The response is rapid and immediately felt. The next diagram exhibits engine response enchancment of 20% as the motive force will increase throttle stress, from zero% opening to huge open throttle. Whereas energy stays unchanged at 441kW (600ps), the result’s a sharper feeling that additional enhances the general character of the hand-assembled VR38DETT.
A revised titanium exhaust system now has a extra emphatic – but not intrusive – tone coming by way of to the cabin. Handcrafted burnished suggestions are a signature contact of the light-weight system.
When in R-mode, the improved 6-speed dual-clutch transmission now shifts gears extra aggressively and intuitively because of a brand new algorithm for the adaptive shift management (ASC). This selects one of the best gear for any driving situation and might particularly be felt throughout braking and method right into a nook, the place the driveline feels extra exact with quicker downshift reactions to assist scale back understeer on entry. With engine pace saved at the next fee because of decrease gear engagement, acceleration additionally improves when powering out of a nook.
Aerodynamics, design and hearty dose of carbon fiber

With aerodynamic beneficial properties in thoughts, the design of the 2020 GT-R NISMO has undertaken an evolution. The adjustments are fully practical, growing cooling of key areas just like the engine bay and brakes, all with out negatively affecting the drag coefficient worth of zero.26.
Additional setting essentially the most potent and unique of all GT-Rs aside from the remainder is the quantity of carbon fiber discovered all through the automotive. Most elements are lighter in comparison with the present mannequin. This consists of the entrance and rear bumpers, entrance fenders (-Four.5 kilograms), hood (-2 kilograms), roof (-Four kilograms), facet sill covers, trunk and rear spoiler. Following the theme of kaizen, every part has been improved to chop weight, enhance downforce and improve aerodynamics. Mixed, these exterior components alone have resulted in a complete weight saving of 10.5 kilograms, becoming a member of the practically 20-kilogram discount by way of upgrades and new elements.
Probably the most vital piece of carbon fiber utility is the roof. New for 2020, the carbon fiber roof removes a considerable quantity of weight the place it counts most, decreasing the automotive’s heart of gravity for improved dealing with and really feel. The roof panel itself is made by utilizing a world-first approach of mixing a Prepreg Compression Molding course of with a carbon plate and light-weight exhausting foam sandwich construction. This offers the carbon construction a tighter and lighter weave, bettering sound insulation and a hanging look. Different adjustments within the carbon fiber building are the NACA ducts on the hood, which at the moment are included into the composite construction.
The GT3 GT-R racecar closely impressed the design of the brand new entrance fenders. They now sport louvres that enhance entrance downforce by 7 kgf with out creating extra drag. The wind tunnel-tested vented fenders additionally assist clean airflow alongside the remainder of the physique and keep away from creating turbulence on the rear wing, selling even better high-speed stability. As a multi-functional characteristic, in addition they assist funnel sizzling pressurized air out and away from the engine bay.
Coloration decisions for the 2020 Nissan GT-R NISMO embrace Stable Purple, Jet Black Pearl, Tremendous Silver Quadcoat and Pearl White Tricoat. All colour schemes characteristic black facet mirrors that differentiate the automotive from different GT-R fashions.
The brakes: Brembo calipers meet carbon ceramic rotors
Nissan collaborated with Italian brake producer Brembo to create an all-new brake package deal for the 2020 GT-R NISMO. Particular massive calipers be a part of carbon ceramic rotors, the most important ever fitted to a Japanese efficiency automotive at 410 mm (16.1 inches) within the entrance and 390 mm (15.Three inches) on the rear.
The six-piston entrance and four-piston rear calipers are exceptionally inflexible. Their all-new building brings a big enchancment to brake response time. This delivers a extra responsive and progressive brake pedal, filled with suggestions to permit exact modulation of braking drive. The result’s the flexibility to shed pace faster and extra successfully whereas staying proof against fade.
The largest benefit comes from the carbon and silicon carbide construction of the rotors themselves. They permit for a 16.Three-kilogram complete drop in unsprung weight. Mounted on floating aluminum billet heart bells, the brand new rotor and outsized caliper setup is completed off by new, specifically formulated brake pads that generate increased friction ranges throughout the total operational vary. The pads additionally give a firmer, extra reassuring pedal really feel.
Entrance rotor cooling has additionally been improved by altering the angle wherein the air guides are mounted, serving to funnel the next circulation of air towards their facilities. As a closing contact, the calipers have been dipped in a heat-resistant yellow paint that’s not solely in a position to endure temperatures over 1,000 levels Celsius however is proof against discoloring from exhausting use and repeated temperature biking.
Dealing with, grip and steering redefined
The 2020 GT-R NISMO’s suspension tuning improves cornering stability (lateral G), with enhanced yaw-rate response and smoother experience high quality. The steering options higher linearity and precision than ever, requiring minimal corrections even at speeds reaching 300 kph (186 mph).
The unique 20-inch RAYS solid aluminum wheels are a mixed 100 grams lighter and incorporate a brand new nine-spoke design that enhances rigidity regardless of the load discount. A diamond-cut white-and-red NISMO emblem on the rim marks their exclusivity.
The newly designed Dunlop tires characteristic a brand new rubber compound, boosting grip by 7%, and a tread sample with one fewer groove for the fronts, which will increase the contact patch by 11%. The tire’s shoulder form is barely rounder in order that when the automotive leans throughout cornering, extra rubber floor makes contact with the bottom, producing extra grip. Total, tire cornering drive is up by 5%. This additionally improves the steering response by way of straight-line monitoring and stability in contrast with the present mannequin, with out impacting rolling resistance efficiency.
The automotive’s Bilstein DampTronic shocks had been fastidiously retuned in each rebound (20% softer) and compression (5% softer) to consider the general close to 30-kilogram discount in weight. The revised spring charges contribute to a extra linear steering response and enhance in road-holding skill.
Additional constructing on the kaizen mentality, extra consideration to element continues proper right down to the chassis and its building. A particular sort of bonding between the welds on the chassis and physique leads to a sturdier-feeling chassis, extra composure over imperfections and extra precision by way of all controls when pushing the automotive exhausting.
Hip-hugging consolation inside
Contained in the cabin, the unique GT-R NISMO entrance seats created by Recaro have been enhanced for 2020 to supply higher containment for the motive force and passenger (not out there within the U.S./Canada). That is achieved by way of a three-layer construction wherein carbon fiber sandwiches a predominant inside part to enhance the way in which the higher physique is supported. The addition of a core body construction to the carbon shell has elevated the torsional rigidity of the seats (approx. 20%), serving to struggle in opposition to flex when pushing exhausting by way of the corners in addition to giving extra common help when actuating the brakes. This did not influence weight negatively: every seat is 1.Four kilograms lighter.
Just one inside colour mixture is accessible, a NISMO-specific black leather-based with crimson accents. The seat inserts are Purple Artificial Suede, and there’s Darkish Grey Alcantara on the steering wheel, dashboard and roof liner.
