History Between 1969 and 1973, and again between 1989 and 2002,
Nissan produced a high performance version of its
Nissan Skyline coupe, the Skyline GT-R. This car proved to be iconic for Nissan, achieving much fame and success on the road and in motorsports. The GT-R was an entirely new model, departing from its predecessor. Though they shared a little with each other, such as the signature four round tail lights, the
ATTESA E-TS Pro all-wheel-drive system, and a
twin-turbocharged 6-cylinder engine, the GT-R diverged significantly. Notably, it omitted the
HICAS four-wheel-steering system, with engineers recognizing its incompatibility with the advanced all-wheel-drive setup, which would compromise the car's performance. The previous
RB26DETT engine was succeeded by the
VR38DETT engine. Another continuity from its predecessor was the chassis code; the all-new version was identified as
CBA-R35 initially and later as
DBA-R35 and
4BA-R35 for subsequent model years, or simply
R35 for short (where CBA, DBA, and 4BA denote the emissions standard prefix). The car also preserved the nickname of its predecessor,
Godzilla, a moniker originally given by the Australian motoring publication
Wheels in 1989 for its R32 generation model.
Development In 2000, as per the request of CEO
Carlos Ghosn, Nissan commenced the revival of their iconic sports car model, as part of the
Nissan Revival Plan. Ghosn believed that introducing a halo car would increase public interest and enthusiasm towards the then-struggling Nissan brand, ultimately bolstering sales. Therefore, he insisted the GT-R should be made as a high-performance car, capable of rivaling esteemed sports cars from manufacturers in the likes of
Porsche,
Lamborghini, and
Ferrari, all while maintaining a comparatively affordable price point. He also sought to preserve a distinctive feature from its predecessors; four round taillights, which he considered the signature design element of all GT-R models. Development began in 2000, with Nissan designers from Japan, US and Europe generating a multitude of sketches. Out of these, 50 designs reached Nissan's design director at the time,
Shiro Nakamura. Nakamura emphasized that the design must not only embody a modern sports car aesthetic but also encapsulate Japanese cultural elements and pay homage to its predecessor's heritage. In 2001, Ghosn officially announced ongoing development of the GT-R, with a concept reveal at the
2001 Tokyo Motor Show. The chief designer, Hiroshi Hasegawa, dedicated over four years to complete interior and exterior designs, as designs should exude sportiness, modernity, and aerodynamic efficiency to meet the ambitious performance targets set for the car. Chief engineer of the Skyline GT-R R34, Kazutoshi Mizuno (also known as
Mr. GT-R), spearheaded the mechanical aspects of development. Mizuno initially rejected the project, due to the directive to build the car on the outdated
FM platform. Mizuno expressed his reservations, stating, "I could not make a world-class performance car from this platform as Ghosn requested." In April 2003, he constructed a
Infiniti G35 based GT-R prototype on an advanced iteration of the FM platform known as the Premium Midship (PM) platform. Mizuno was then granted the full development authority and was designated as the chief engineer of the GT-R. At the
2003 Tokyo Motor Show, Ghosn confirmed that the production version would debut in the fall of 2007. Subsequently, the prototype underwent refinement at
Lotus Engineering, focusing on enhancing chassis rigidity and revising suspension geometry to align with the car's performance goals. In January 2004, Mizuno officially commenced development with a specialized team and a full-scale GT-R model. Differing from the typical development team, this specialized group was made by recruiting the best engineers and technicians from each department. The Mizuno-led team developed and tested the drivetrain and chassis, including the suspension setup and brakes, using the Infiniti G35 test mule at the
Nürburgring and
Sendai Hi-Land Raceway. Mizuno claimed his ambitious goals were to build the GT-R so as to be able to have comfortable conversations with a passenger at speeds of . Furthermore, he aimed for a power-to-weight ratio of under per horsepower and a lap time at the Nürburgring in under 8 minutes. Notable mechanical designs and concepts, including the
Brembo brakes system and the
Bilstein suspension setup, were conceived and developed by Mizuno himself. Initial plans for the GT-R involved a straight-6 engine, consistent with its predecessors. However, the decision was made to opt for a shorter
V6 engine for ideal weight distribution. Nissan's chief powertrain engineer, Naoki Nakada, spearheaded the development of the brand-new
VR38DETT 3.8L twin-turbocharged V6 engine, which was an evolution of the
VQ engine. To achieve the initial goal of creating a high-performance user-friendly car, a unique combination of production car and race car-like
aerodynamics had to be developed. This challenge arose from the dual requirements of generating a respectable amount of
downforce for enhanced high-speed stability while maintaining minimal
drag for improved fuel efficiency. Initially, engineers expressed the complexity of achieving such an aerodynamic level, given a road car's high ground clearance, safety regulations, visibility standards, material costs and various other factors. Aerodynamics development began in early 2004, spearheaded by a team of the company's best engineers, including Yoshitaka Suzuka, the developer of Nissan's successful Le Mans prototypes. The process began with an internal design competition among Nissan's design studios located in
Atsugi,
Tokyo,
London, and
La Jolla. Over 80 sketches were submitted, aligning with the original styling concepts. Subsequently, 12 distinct sketches were created by design elements from the initial submissions. Further refinement whittled them down to 3 scale wind tunnel models created by the development team. The team set a numerical target for the car to achieve a or lower, combined with front and rear downforce, which was not done by any other manufacturer. Suzuka initially proposed utilizing active aerodynamics, but the idea faced rejection due to the concerns of inflating the car's price beyond Nissan's planned offering. In August, Suzuka initiated wind tunnel testing at the Nissan Technical Center in Atsugi, spanning three months and involving over 300 test runs using the scale models. The program then transitioned to two 40 percent scale models—one representing the GT-R and the other replicating the Infiniti G35 test mule. Drawing data from its full sized version's testing at the Nürburgring, this scale model served as a comparable datum against the GT-R model. Initial wind tunnel tests with the GT-R model yielded a drag coefficient of . As the project progressed, exterior designers Hirohisa Ono and Masato Taguchi joined to refine certain aspects of the car, such as adjusting the front nose height. However, the efforts fell short of achieving the anticipated overall improvement in aerodynamics. Over one and a half years of development, involving more than 2000 wind tunnel test runs, the engineers ultimately achieved a visually appealing exterior design with a drag coefficient of combined with front and rear downforce.
Concepts Nissan unveiled the GT-R concept without prior notice at the 35th Tokyo Motor Show in 2001. Previewed as the 21st-century GT-R, Nissan confirmed the production version will be sold worldwide unlike its predecessors, which were sold only in a limited number of markets. The concept car featured an aggressive, muscular, wide and low exterior look. The interior featured a deep seating position, full-length centre console, integrated structural cage and a driver's command centre. Nissan unveiled a redesigned version of the concept car, the GT-R Proto, at the
2005 Tokyo Motor Show. It featured redesigned exterior elements over the concept car to improve overall airflow and reveal the identity of the car. These elements included a redesigned front air intake, front fenders with air vents behind them and the sides of the body were sculptured towards the rear fenders, no technical information were given for both concept and prototype cars. Officials claimed the production version would be 80 to 90 percent based on this prototype.
Testing As overall development of the car was finalized around 2006, Nissan began testing in several countries on different road and weather conditions to fine tune the all-new performance car. In late 2004, the Infiniti G35 test mule was spied at the
Nürburgring, it featured highly modified body panels, drivetrain, suspension and braking setups. In late 2006 and early 2007, GT-R test mules were spied for the first time, alongside a
Porsche 911 Turbo on public roads in New Mexico and California, at race circuits such as in the Nürburgring and
Laguna Seca. During a test session at the Sendai Hi-Land Raceway, Ghosn joined the test team to directly test drive the car against a
Porsche 911 Turbo, which served as the benchmark during the development of the GT-R. At the end of the session, he complimented the team for their effort to build the car in the way he imagined. During a test session at the Nürburgring, Nissan invited automotive journalists of magazines in the likes of
Car and Driver and
Evo to test drive both the GT-R and 911 Turbo around the track,
Autobahn and on country roads. Journalists praised the GT-R for its exceptional grip, handling and acceleration. End of overall testing in September 2007, Mizuno and team recorded a lap time of 7:38.54 minutes around the Nürburgring
Nordschleife in damp conditions, claimed the car would have set a much quicker lap time on ideal track conditions. Following the introduction of the production version, the team continued development and testing to provide upgrades for later model years. == Production ==
