Mazda RX-7

After a successful Le Mans in 1991, in which Mazda came first with its 700bhp, (522kW) high-revving R26B rotary-powered car, the new RX-7 made its debut. It immediately jumped from sportscar to supercar, thanks to a design brief which stated the car had to be as light and fast as possible. While the shell was steel, the advanced double wishbone suspension was all-alloy, and components were directly bolted to the chassis without bushings for more precise handling. Alloy cross braces were used within the body, making a very stiff structure. The engine was based on the original twin rotor Wankel design, and having few moving parts meant it could rev very quickly. The key was the twin-turbo set-up, one of which started the lag-free performance, the other joining in at 4,500rpin, whereupon it would rapidly rev to its redline.
