Nissan R390 GT1 The Nissan R390 GT1 is a prototype sports car developed by Nissan Motors and constructed by Tom Walkinshaw Racing for competition in the 24 Hours of Le Mans and FIA GT1 World Championship events. Conceived to homologate a road-legal variant for the GT1 class, the R390 combined expertise from Nissan Performance Technology Inc., Autech, and designers associated with Prodrive alumni to challenge factory entries from Porsche AG, Toyota Motor Corporation, and Mercedes-Benz at endurance races. Debuting in 1997, the R390 program aimed to leverage technologies from Nissan Skyline and Nismo engineering within an Le Mans Prototype-style body.
Nissan initiated the R390 project to return to top-level sports car racing after campaigns with the Nissan R89C and Nissan R90C. Development was led by a collaboration between Nissan Motorsports International and Tom Walkinshaw Racing, with aerodynamic work influenced by designers who had worked on the Jaguar XJR-14 and Porsche 911 GT1. Chassis philosophy incorporated a carbon-fiber monocoque derived from lessons learned at 24 Hours of Le Mans programs run by TWR and Team Lotus. Suspension geometry and packaging reflected inputs from Nismo engineers and consultants from TWR's Le Mans efforts, while the bodywork featured prominent aerodynamic devices similar to those on the McLaren F1 GTR and Mercedes-Benz CLK GTR to optimize downforce for Circuit de la Sarthe high-speed sections.
Powertrain centered on a bespoke Nissan VRH35L 3.5-liter twin-turbocharged V8 developed by Nissan Performance Technology Inc. and refined by Nismo specialists with turbocharger systems influenced by suppliers used in Formula One and IndyCar engine development. Transmission was a sequential gearbox supplied by Xtrac engineers who had previously worked with Mazda Motorsports and Porsche Motorsport. Braking components were carbon-ceramic units specified by partners that included firms who had supplied McLaren F1 and Bentley Motors endurance programs. Aerodynamic tuning used computational fluid dynamics tools comparable to those employed at Ferrari and Aston Martin Racing, with downforce and drag balance tailored for Chicanes and long straights of Le Mans.
The R390 made its racing debut at the 1997 24 Hours of Le Mans, entering under the Nissan Motorsports International banner against factory efforts from Porsche AG, BMW Motorsport, and Toyota Team Europe. After initial reliability challenges similar to earlier GT1 ventures such as the Porsche 911 GT1, the team returned in 1998 with upgraded cars, improved by lessons from Courage Compétition and Sauber-Mercedes endurance campaigns. At the 1998 24 Hours of Le Mans, the R390s achieved competitive pace, finishing in the top positions and demonstrating endurance reliability improvements akin to developments made by Peugeot Talbot Sport and Audi Sport in their prototype programs. The R390 also competed in selected rounds of the FIA-sanctioned GT Championship and in endurance events that attracted entries from Schnitzer Motorsport and Martini Racing-backed teams.
On track, the R390 combined straight-line speed competitive with Toyota GT-One and Porsche 911 GT1 EVO rivals while featuring handling characteristics reflecting aerodynamic concepts used by Benetton and Williams Racing aerodynamicists. Though the R390 program was short-lived, its engineering influenced later Nissan and Nismo projects, including lessons applied to Nissan GT-R performance variants and endurance research pursued by Nissan Motorsports personnel who later collaborated with manufacturers such as Infiniti and Renault Sport. The R390 remains celebrated by collectors and historic racers, appearing at Goodwood Festival of Speed and Le Mans Classic events alongside cars from Group C and IMSA heritage grids.
A limited number of road-homologation R390 GT1s were produced through Autech, mirroring strategies used by Mercedes-AMG and McLaren Automotive to meet GT1 class regulations. These road variants featured modified interiors by firms specialized in coachbuilding such as those employed by Porsche Exclusive Manufaktur and Mansory, and retained the VRH35L powerplant detuned for road use similar to approaches taken by Jaguar with the XJ220. Racing evolution versions received upgraded aero packages and mechanical components analogous to iterative developments seen in Porsche Motorsport and BMW M Motorsport programs.
