Unveiled by Nissan at the 2007 Tokyo Motor Show, the new GT-R was designed as an all-new model and inspired by the 2005 GT-R Proto concept car. The design is characterized by aggressive lines and high aerodynamic performances, with a Cd of 0.27.

Technical features

Nissan GT-RThe Nissan GT-R is powered by an all-new 3.8-litre twin turbo V6 engine which produces 480hp (353kW) at 6400rpm and a maximum torque of 60kgm (588Nm) from 3200 to 5200rpm.

It is coupled with the first independent transaxle 4WD developed independently by Nissan, which features a dual clutch transmission, with paddle shifting and a Borg Warner six-plate dual clutch for direct control.

The dual-clutch transmission, transfer case and final drive are placed at the rear of the vehicle (instead of the usual front location), which enables vehicle weight to be evenly distributed throughout the car.

The braking system features large Brembo full-floating drilled rotors, low steel high stiffness brake pads and Brembo mono block six-piston front and four-piston rear callipers.

The specifically-developed run-flat tires are designed to maintain their integrity for 80km of travel at 80 km/h and also provide a level of performance after a loss of pressure.

Exterior Design

The design bears a close resemblance to the GT-R Proto shown at the 2005 Tokyo Show and, in turn, has much in common stylistically with the 2001 GT-R Concept.

‘We wanted to design a car that looked uniquely Japanese – it is very definitely not a European or American fast car,’ says senior vice president of design Shiro Nakamura.

Nissan GT-R“We also wanted to highlight the functionality of the car – it is a car that is easy to use and easy to drive – and continue the proud heritage of the GT-R.”

The new Nissan GT-R is “chunky, edgy, wide shouldered, ground-hugging and flat-sided, it is also one of the most aerodynamic cars in the world (Cd 0.27).”

Compared to the GT-R Proto, the only significant styling difference – apart from small details – is to the front styling, changed mostly to allow for superior crash test protection.

This is the first GT-R not based on a mass-volume Nissan vehicle (the last GT-R was based on the Skyline).

Nissan GT-RThat gave design director Shiro Nakamura, product chief designer Hiroshi Hasegawa and their team a great deal of freedom in the creation process.

“The mission was to achieve a distinctive car, a supercar, but not a normal fast car – it’s chunkier, more practical and more muscular,” says Nakamura.

“The element of functionality is core to the GT-R. It’s not too low; it’s easy to get in and out of, has good visibility and is easy to drive. That functionality is reflected in the design. It is clearly not an Italian, German or American car – it is unmistakably Japanese.

“It is very mechanical, almost like an animated robot – it is obviously made from metal, has big shoulders and looks strong and muscular. The previous R34 GT-R had the same image. Almost like you could be playing this car on a video game.

“We didn’t want a nice elegant shape – we wanted an original shape. Some people who buy this car will also have a Ferrari and a Porsche. This car must be different from all others. I see it as a car influenced not by feminine beauty, like Italian cars, but by masculine beauty – it is strong, well toned, well muscled. It has big deep flanks and is very toned – that’s part of the muscled stance.”

Nissan GT-RThe kink in the rear pillar “is highly distinctive and helps rear airflow,” says Nakamura, “and it also gives the GT-R a really unusual roof line, which I like.”

The side front fender air scoops also improve the car’s aero performance by improving airflow around the tires, are highly distinctive and almost animalistic. They also help cool the twin-turbo V6.

Nakamura also feels those deep flat sides are highly functional. “They’re flat like a well toned stomach but they also help when judging the car’s width and they’re very aerodynamic.”

“Designing a car is always a balance between engineering and aesthetics. But with the Nissan GT-R we had very little conflict. We knew this car had to be Nissan’s technological showcase. Our designers worked very closely with the aerodynamicists to ensure excellent air flow and good downforce essential for a car that has such a high top speed and such excellent high speed stability.”

Nissan GT-RThe new car also continues the GT-R design lineage. “It’s quite square and edgy at first glance although full of interesting curvatures and subtle shapes when you look closer. Like all great design, the closer you look, the more you see.”

The pillars are quite upright, emphasizing that this is not an impractical low-slung supercar. There are the four round tail lamps mirrored in the four chunky round exhausts directly below.

Specific styling cues, borrowed from great Nissans of the past, include the edgy boxy shape of the PGC10 GT-R of 1969, the four round tail lamps of the KPGC110 GT-R of 1973 and the long thin slit grille opening of the R34 GT-R of 1999.

Nissan GT-RGT-R’s body is created with a combination of steel, carbon fibre and aluminium, providing a combination of stiffness and lightness.

The front bumpers express power and stability, while the “aero-blades” on the leading edges provide optimum airflow around the tires and along the body.

The scoop in the bumper trailing edges assists in providing front down-force and optimisation of side airflow.

The aggressive front end, with a large hood bulge and single air intake, provides a sophisticated style as well as undisturbed airflow for power and cooling.

The silhouette is defined by the sloping “aero blade canopy” roofline and curved C-pillar “sword edge,” which expresses the distinctive GT-R identity, as well as facilitating air flow around the rear of the vehicle.

The rear end is characterize by the GT-R’s hallmark four-ring taillights, rear spoiler and large, integrated exhaust tips. The paint utilises a “double clear coat” and “anti-chipping” process and is hand-polished.

Interior Design

Nissan GT-R - InteriorLike the exterior, the Nissan GT-R’s interior is stylish but highly functional.

The cabin is unique, sharing no major components or design features with any other Nissan model.

Instruments are large, clear and simple, all directly in front of the driver for maximum legibility.

The circular analog instruments are ringed in chunky bezels and the tachometer is red-lined at 7000rpm and integrates a gearshift position display.

The design of the multi-function display – which also includes the satellite navigation and audio controls – was done in conjunction with Polyphony Digital Inc, designer of the Gran Turismo video game series for Sony PlayStation.

In the center of the dashboard, below the multi-function display, is a cluster angled towards the driver.

The center console, which sweeps through the middle of the cabin, contains the red start button, the leather shift lever and parking brake, which aligns with the center armrest when off, functioning as an extended arm rest.

There is a full automatic gear change provision, useful in heavy traffic or when relaxing rather than sporty driving is desired.

Seats are especially designed for the Nissan GT-R. They’re heavily side bolstered for maximum lateral support and comfort and feature a wide range of adjustments.

Nissan GT-R - InteriorThe rear seats are more ‘occasional’ seats than full-size chairs.

The center console sweeps through the middle of the cabin, dividing left and right rear seats. Between the seats there is the provision for optional two BOSE sound system woofers.

The trunk is large (VDA: 315L), also thanks to the run-flat tires which obviate the need for a spare tire.

The seat has three color schemes: black, black with red highlight or gray.

Says design director Shiro Nakamura: “An underlying philosophy of the Nissan GT-R is that it is a fast car that’s easy to drive fast. So there is nothing intimidating about the controls. Everything feels instantly familiar, apart from the novel multi-function meter – which is also highly intuitive and we believe will prove very popular with owners.”
