The Nissan R390 GT1 was a racing car built in Atsugi, Japan. It was designed primarily to gain a suitable racing entry in the 24 Hours of Le Mans in 1997 and 1998. It was built to race under the grand touring style rules, requiring a homologated road version to be built. Therefore, the R390 was built originally as road car, then a racing version of the car was developed afterwards. Only one R390 road car was ever built and is stored at Nissan's Zama facility, although one of the race cars was later modified for road use. The road car was claimed to be capable of attaining a top speed of 354 km/h (220 mph). However, this claim has never been proven.

The Nissan Skyline GT-R is a Japanese sports car based on the Nissan Skyline range. The first cars named "Skyline GT-R" were produced between 1969 and 1972 under the model code KPGC10, and were successful in Japanese touring car racing events. This model was followed by a brief production run of second-generation cars, under model code KPGC110, in 1973.
