The sill section ahead of each rear wheel was extended downwards to improve air flow. To direct more air to the engine, a body coloured lip spoiler was added to the leading edge of the bonnet (between the headlights).įor extra downforce, a secondary spoiler was mounted on the trailing edge of the boot lid underneath the standard wing. BodyworkĮxternally, two rectangular intakes were cut from the front bumper which fed more air to the intercooler. Nismo focused their attention on refining the aerodynamics, reducing weight and improving reliability. They retailed at a 5% premium over the standard model.Īn additional 60 examples were manufactured that Nissan held back for competition use. Nissan would follow a broadly similar path with the R32 GT-R.ĭevelopment was handled by the firm’s in-house motorsport division, Nismo (Nissan Motorsport International Limited).ĥ00 of the resultant GT-R Nismo variants were built between December 1989 and March 1990.
The RS500 came with a host of upgrades over the standard Sierra Cosworth to include a special engine block, bigger turbo, bigger intercooler, uprated oil and cooling system, a reworked induction system and revised aero pack. The FIA required 500 Evolutions to be built within a twelve-month period compared to 5000 units of the original base model.Īrguably the most famous machine to exploit Group A’s Evolution regulations was the car Nissan had to beat on track: Ford’s Sierra Cosworth RS500. The FIA Group A motor sport regulations that Nissan designed the R32 Skyline GT-R for also permitted manufacturers to build batches of Evolution models.Įvolution variants enabled firms to make further modifications and were permitted once the base model had been homologated.
