Some might have thought that the powertrain in this c1980 Mazda RX-7 was the powertrain of the future. It was thought that its more compact design, smoother operation, and fewer moving parts would lead to the eventual demise of the reciprocating piston design of conventional internal combustion engines. Mazda bought big into the rotary engine fad, producing a ton of them in various vehicles, starting with the gorgeous Cosmo sports car in 1967, and ending with the 2012 RX-8. The biggest problems with the rotary engine were comparatively poor gas mileage and emissions numbers, and a short rotor life — an expensive repair. Saw this early RX-7 example over the summer in Kenmore.
