The ultra-fast and super expensive Nissan street-car was manufactured to conform to the Le Mans GT1 Class regulations that required manufacturers to build at least one street-legal version of the race car. Unlike many others, Nissan built the road car first and built the racing version from it. Legendary car designer & current Chief designer at Jaguar, Ian Callum who was the brain behind the Aston Martin DB7’s design, conceptualized the R390 at the Walkinshaw Racing facility in England. Priced at a hefty $100,000, only two working models were ever produced and it is unclear whether any of them were actually sold (one of them is currently housed in Nissan's own museum). Following suit with rival competitors like Chrysler, Porsche and Mercedes, the R390 was among a select few short run homologation models manufactured purely to comply with entry regulations into GT racing. Industry experts opined that one of Nissan’s primary objective behind the R390 GT1’s manufacture was to push consistency and forceful performance to the outright limit without compromising upon the drivability of a street car.
