Chronology
PredecessorNissan Skyline GT-R

The Nissan GT-R is a coupé created by Nissan, released in Japan on 6 December 2007, and expected to be released internationally by late 2008. Nissan and the automotive press frequently refer to the GT-R as a supercar.[3][4][5]

History

Nissan Skyline GT-R

Between 1969 and 1974, and again between 1989 and 2002, Nissan produced a high performance version of its Skyline range, called the Nissan Skyline GT-R. This car proved to be iconic for Nissan and achieved much fame and success on road and track. The Nissan GT-R, although no longer carrying the "Skyline" badge, has heritage in the Nissan Skyline GT-R. Like the Skyline GT-Rs R32 through R34, the Nissan GT-R is All-Wheel Drive with a twin-turbo 6 cylinder engine; however, the evolutionary, incremental changes between Skyline models R32 through R34 have been done away with. The four-wheel-steering HICAS system has been removed, and the traditional straight-6 RB26DETT engine has been replaced with a new V6 VR38DETT.[6] Because of the GT-R's heritage, the chassis code for the all-new version has been called CBA-R35,[7] or 'R35' for short, carrying on the naming trend from previous Skyline GT-R generations.

Concepts

GT-R Proto at the 2005 Tokyo Motor Show

Two concept vehicles were displayed at motor shows prior to the unveiling of the production model. The first concept was shown at the Tokyo Motor Show in 2001 to preview what a 21st century GT-R would look like.[8] At the 2005 Tokyo Motor Show, Nissan unveiled a redesigned concept, the GT-R Proto, stating that the production GT-R would be 80-90% based on this concept.[citation needed]

Production

The production version of the GT-R has debuted at the 2007 Tokyo Motor Show, with its launch in the Japanese market scheduled for 6 December 2007. The U.S. Official launch was July 07, 2008. Universal Nissan in Los Angeles provided a customer with delivery at 12:01 am, on July 07, 2008. Canadian launch will follow in July 2008, respectively. Europe will be the third market, where it is expected to be launched late in the same year. The large time distance between these releases is due to Nissan having to build GT-R performance centres where the car is serviced. Also the engine and rear-mounted dual-clutch gearbox are built by hand, limiting production to around 1000 cars a month.[9] US Prices start at $69,850 for the base model. Premium model starts at $71,900. [10]

Higher performance model

Production gauge cluster

It has been confirmed that Nissan is planning to introduce a lighter and more powerful GT-R called the GT-R V-Spec,[11] or possibly Spec V.[12] Nissan has said that this model will be available in the United States in 2010[13][14] and will have 550 bhp (410 kW) (an increase of 77 bhp (57 kW)). It will also be 330 pounds (150 kg)* lighter and come with carbon ceramic brakes. With these performance figures Nissan hopes to break the Nürburgring lap record for a stock vehicle.[15] A prototype has allegedly been observed by spectators running laps in the 7 minute 25 seconds range.[16]

Specifications

The VR38DETT engine

The Nissan GT-R is powered by the VR38DETT engine, a 3.8 L (230 cu in) DOHC V6. Two parallel Ishikawajima-Harima Heavy Industries (IHI) turbochargers provide forced induction.[17] Production vehicles produce 480 bhp (360 kW) at 6,400 rpm and 430 lbf⋅ft (580 N⋅m) at 3,200-5,200 rpm.[18] According to independent dynanometer tests, the GT-R produces 416 hp (310 kW) to 475 hp (354 kW) and 414 to 457 lb⋅ft (620 N⋅m) of torque at the wheels.[19][20][21][22][23] The engine also meets California ULEV (Ultra Low Emissions Vehicle) standards.[24] A curb weight of 1,730 kg (3,810 lb) or 1,736 kg (3,827 lb) with side curtain airbags is achieved using a jig welded steel chassis with aluminum used for the hood (bonnet), trunk (boot) and doors.[25] A rear mounted 6 speed dual clutch semi-automatic transmission is used in conjunction with the ATTESA E-TS system to provide power to all four wheels and along with Nissan's Vehicle Dynamics Control (VDC-R) aids in handling and stability. Three shift modes can also be selected for various conditions. The drag coefficient is 0.27.[26]

Performance

Nissan claims a top speed of 190 mph (310 km/h) and has been tested to achieve 0-60 mph (97 km/h) times around 3.4 seconds.[27][28] Edmunds.com achieved a standing 1/4-mile time of 11.6 s at Template:Auto km/h using the GT-R's launch control system. Edmunds also speculated that faster times may be achievable on better road conditions than provided by the runway which they used for the test.[29] Car and Driver achieved a standing 1/4-mile time of 11.5 s at Template:Auto km/h.[30] Evo magazine achieved a 0-100-0 mph time of 13.9 seconds.[31] AutoCar achieved a 0-100 MPH time of 8.5 seconds.[32] With a lap time of 7:29 sec on standard Japanese market tires, the standard-spec GT-R is currently one of the fastest production cars ever to lap the Nurburgring circuit.[33][34]

In various comparisons under different criteria, the GT-R has outperformed the Audi R8, Chevrolet Corvette Z06, BMW M3 E92, Lotus Elise, Mitsubishi Lancer Evolution X, the three current Porsche 911s (Carrera, Turbo, and GT3), and the Subaru Impreza WRX STI.[35][36][37][38][39][40][41][42]

Several automotive journalists, including Chris Harris of Autocar,[43] Jethro Bovingdon of Evo,[44] and Jason Barlow of Top Gear (magazine)[45] have compared the GT-R to the Bugatti Veyron. Harris and Bovingdon both labeled the GT-R a "baby Veyron" in their respective comparison tests of the car.[43][44]

Design

The customizable multifuction display integrated into the dash of the GT-R

Nissan chief creative officer, Shirō Nakamura, has likened the new GT-R to the eponymous giant robots of the Gundam series. Nakamura states: "The GT-R is unique because it is not simply a copy of a European-designed supercar, it had to really reflect Japanese culture." Specifically, Nakamura noted that the GT-R's square lines and vents were influenced by Gundam. Designers from Japan, America, and Europe contributed to the final GT-R shape.[46][47]

Polyphony Digital, creators of the Gran Turismo series of racing video games, were themselves involved in the development of the GT-R, having been contracted to design the GT-R's multifunction display.[48]

Comparison Testing

In the April 2008 issue of Evo magazine the GTR posted a faster time at Bedford Autodrome than the Porsche 997 GT3.[49]

In another Evo magazine test the GTR competes in three tests. It first beats the Corvette Z06 on a short drag strip, then the Audi R8 on the street and lastly the 997 GT3 around the track.[50]

An April 2008 comparison by Car Magazine shows the GTR running faster around Rockingham circuit than the Porsche 911 Turbo, Audi R8, and BMW M3.[51]

A May 2008 comparison by Edmunds.com placed the GTR up against the Audi R8, Lotus Elise SC, Porsche 911 Carrera, Mitsubishi Lancer Evolution X MR and Subaru WRX STI. Dodge and GM were asked to take part but declined. The GTR managed to outperform all its competitors on both the Streets of Willow Spring and a section of the Angeles National Forest.[52]

Road and Track tested the GTR, Corvette Z06 and 911 Turbo on Buttonwillow. The GTR with a time of 1:56.9 was quicker by over five seconds.[53]

In a July 2008 test conducted by Autoexpress the GTR defeats the Audi R8 and Jaguar XKR-S.[54]

A July 2008 Car and Driver comparison placed the GTR second in a three-way comparison with the Porsche 911 Turbo and BMW M3. While the M3 won overall, both the BMW and Porsche were slower around the Reno-Fernley road course.[55]The Truth About Cars joked Car and Driver must have given the victory to BMW based on advertising revenue.[56]

In August 2008 Car and Driver again tested the GTR, this time against the Chevy Corvette Z06, Dodge Viper SRT10 ACR, and Porsche 911 GT2 around Buttonwillow. The GTR won this comparison, however it was badly beaten by the Viper and GT2 at the track. The GTR ran 2:01.1 considering slower than the time Steve Millen acheived for Road and Track. However the Corvette Z06 posted similar times in both comparisons.[57]

Motorsport

Nismo GT-R for 2008 season of Super GT

Nismo, the motorsport arm of Nissan will be entering the Nissan GT-R in the Super GT race series in the GT500 class for the 2008 season, replacing the Nissan 350Z.[58]

Unlike the production car, the GT500 version has a completely different drivetrain. The race car has a 4.5 liter naturally-aspirated V8 with 6 speed sequential manual gearbox and a RWD layout from its predecessor, the 350Z race car.[59]

A prototype was spotted testing around the Suzuka Circuit as well as Fuji Speedway in Japan.[60][61] The car itself went on to win the opening race of the 2008 Super GT season at Suzuka scoring a one-two finish for Nissan.[62] The dominant performances in the opening race has led to all GT-Rs being applied a 50kg weight penalty in addition to the race weight penalty under the Special Adjustment of Performance under the Super GT regulations.[63] In race two, the GT-R repeated their 1-2 result in Suzuka despite the race winning car of team Nismo carrying a 100kg weight penalty making it only the 3rd team in JGTC/Super GT history to do so. The last time this feat was achieved was 10 years ago by Nismo Skyline GTR racing under the same number 23.[64]

A production-based Nissan GT-R made its world motorsport debut in Australia's Targa Tasmania tarmac rally in April 2008,[65] however it did not complete the rally due to damage.[66]

Aftermarket tuning

Despite early concerns about the difficulty of modification of the Nissan GT-R, a number of modifications have been released. The previously reported "untuneable" ECU has since been hacked by several tuning houses.

MINE'Shas officially de-coded its ECU and others have bypassed such as MCR,[67] HKS, and Top Secret. They have been seen testing modified GT-Rs with the former two having conducted tests at the Tsukuba Circuit.[68] Sources from Mine's and Nissan revealed that the reason of the GTR is having tight restriction of modifying is because its gearbox is not rigid and durable enough to overtake an excess of 600PS. Since Nissan worries tuners might over tune them like its predecessors, they decided to lock the car in such ways. However Mine's is working on gear changing calculations hoping smoother gear change plus improved air ducts under the gearbox could solve the problem.

In a review by Motor Trend editor Scott Kanemura, it was revealed that the GPS system fitted to the GT-R would remove the 180-kilometer per hour (112 mph) speed limiter when the car arrives at a race track, but only on tracks approved by Nissan. Aftermarket ECUs have been developed to bypass the speed limiter, in addition to stand-alone speed-limiter defeaters. However, Nissan confirmed the GPS check is not implemented in American models.[69]
