The Nissan R390 GT1 was a mid-engined super 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 tourer 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 after. Only one R390 road car was ever built and is stored at Nissan's Zama facility.
The road car was claimed to be capable of 220 mph, which surpassed the Jaguar XJ220 and RUF CTR2, but was superseded by the McLaren F1's 230+ mph claim and the Dauer 962 Le Mans's independently measured 251.4 mph. However, this claim has never been proven.
