Generation of skyline GTR

First generation

Production	1969–1972
Body style	4-door sedan 2-door coupe
Layout	FR layout
Engine	2.0L 160 horsepower (120 kW) S20I6
Transmission	5-speed Manual
Designer	Shinichiro Sakurai

The first Skyline GT-R, known by the internal Nissan designation PGC10, was released on February 4, 1969. It was available originally as a four-doorsedan after a public debut at the October 1968 Tokyo Motor Show. It was advertised alongside the Nissan R380 racecar to showcase the Skyline's racing heraldry. It was equipped with the 2.0 L DOHC S20 I6 producing 160 hp (120 kW) at 7000 rpm and 177 N·m (131 ft·lbf) of torque at 5600 rpm. Power was delivered to the rear wheels by a 5-speed manual transmission. The first Skyline GT-R rode on a semi-trailing arm strut suspension. It was available as a coupe in March 1971 with the chassis code KPGC10.

Second generation

Production	1973
Body style	2-door coupe
Layout	FR layout
Engine	2.0L S20 I6
Transmission	5-speed manual
Designer	Shinichiro Sakurai

The KPGC10's successor, the KPGC110, was released in 1973 after its introduction at the 1972 Tokyo motor show. Powered by a 1989 cc I6 S20 engine, the second generation GT-R delivered power to the rear wheels through a 5-speed manual gearbox. The suspension was a semi-trailing ring arm setup and minor aerodynamic parts were added.

This edition of the GT-R was also known as the "Ken & Mary" Skyline, due to a popular advertisement featuring a young couple (Ken and Mary) enjoying the Hokkaido countryside. The advertisement later spawned a hit song by Buzz, and the tree featured in the advertisement later became a minor star itself.

Unfortunately, the second generation GT-R was unsuccessful, for a gas crisis hit in the early 1970s, drying out any demand for high-performance sports cars. A total of 197 cars were built by the end of its short production run. For the next decade, this would be the last GT-R until the production of the R32 in 1989.

Third generation

Production	1989–1994
Body style	2-door coupe
Layout	Front engine, rear-wheel drive /four-wheel drive
Engine	2.6 L RB26DETT I6
Transmission	5-speed manual
Designer	Naganori Ito

This new 2.6 L all wheel drive concept was put into production as the R32 Nissan Skyline GT-R. The R32 developed 206 kW (276 hp) and 266 lb·ft (361 N·m) of torque, it had a curb weight of 1,430 kg (3,146 lbs). Initial production of the car was the required 510 to allow for homologation starting on May 22, 1989. Its successful debut along with critical acclaim by the motoring press created a heavy demand for the car. Nissan officially started an unlimited production run August 1989, and began its Group A campaign in 1990. Due to strict Group A homologation rules, Nissan was required to also sell a series of the Skyline GT-R which more accurately reflected the car they use in Group A racing. This series was called the Skyline GT-R 'Nismo' edition.

Fourth generation

Production	1995–1998
Body style	2-door coupe 4-door sedan
Layout	Front engine, rear-wheel drive /four-wheel drive
Engine	2.6 L RB26DETT I6
Transmission	5-speed manual
Designer	Kozo Watanabe

The E-BCNR33 (R33) was developed in 1995 as a successor to the venerable R32 model. The engine in the R33 was nearly identical to the R32. It used the same turbochargers and the same specification for the manual gearbox, although the syncros were made to be stronger. The engine corrected the R32's weak oil pump drive collar, which tended to fail in higher power applications, with a wider collar. The base model R33 GT-R weighs 1,540 kg (3,400 lb).^[13]

The R33 GT-R launched in January 1995 with the base model GT-R and the V-spec model. The V-spec model weighed in 10 kg (22 lb) heavier, and had sportier suspension resulting in lower ground clearance. The V-spec also featured the newer ATTESA E-TS Pro all wheel drive system, which included an Active Limited Slip differential. The V-spec model also included a four wheel independent channel anti-lock braking system.

Fifth generation

Production	1999–2002
Body style	2-door coupe 4-door sedan
Layout	Front engine, rear-wheel drive / all-wheel drive
Engine	2.6L RB26DETT I6
Transmission	6-speed manual
Designer	Kozo Watanabe

The GT/GF-BNR34 (R34) Skyline GT-R and GT-R V-spec models were released in January 1999. The R34 GT-R was also made to be shorter (from front to rear), and the front overhang was reduced. The valve covers were also painted glossy red, rather than dull black.

A new feature on the R34 GT-R is a 5.8" LCD multifunction display on the center of the dashboard, which shows seven different live readings of engine and vehicle statistics such as turbocharger pressure (1.2 bar max), oil and water temperature, among others. The GT-R V-spec model added two extra features to the display: intake and exhaust gas temperatures. Nismo Multi-function Displays (MFD) can be bought at an extra cost, they include a lap timer, G-Force meter and an increase in boost pressure measurement to 2 bar. The R34 GT-R was made shorter in response to customer concerns who thought the R33 was too bulky.

Like the R33, the new R34 GT-R V-Spec (Victory Specification) models come equipped with the ATTESA E-TS Pro system and an Active LSD at the rear, while standard GT-R models come with the non-Pro system and a conventional mechanical differential. The V-spec model also had firmer suspension and lower ground clearance, thanks to front and side splitters, as well as a rear carbon fiber air diffuser, designed to keep air flowing smoothly under the car.
