1978 Rotary Speed

Car & Driver Editor Don Sherman set a Class E record at the Bonneville Salt Flats in Utah on this day, driving the Mazda RX7, the standard-bearer for the rotary engine in the U.S. market, and reaching 183.904mph. The RX7's unique rotary engine doesn't have the standard pistons, instead, two rounded "rotors" spin to turn the engine's flywheel. Although the rotary engine was not a new concept, the Mazda RX7 was one of the first to conquer the reliability issues faced by earlier rotary engines. Light and fun to drive, with 105hp from its 1.1 liter rotary engine, the RX7 was extremely popular.
