History

Originally developed to be used in the Nissan P35 race car for Group C racing, the VRT35 would later see use in the 1992 All Japan Sports Prototype Championship. Required to be 3.5-litres by Group C rules, the engine had to not only be high-revving like a Formula One engine, but also have endurance capabilities. Nismo produced an engine at 3.5 L (3,499 cc) named the VRT35, with claims of 630 PS (463 kW) and capable of reaching nearly 12000 rpm. The VRT35 would be a V12, in contrast to Peugeot, Toyota, and Mazda's V10 units. Johnny O'Connell, a test driver for the Nissan P35 race car once said "Well it was about the most amazing sounding engine I have driven. It totally screamed.".^[1]
