Mazda RX-7
Muscle cars are often defined by their cylinders. How many are under the hood? Six, eight, ten, twelve? How about one? Mazda’s unique Wankel rotary engine eschews traditional pistons, instead relying on two rotors and an output shaft operating in one cylinder. Of all the rotary-powered cars ever made, the Mazda RX-7 is perhaps the most well-known. From 1978 to 2002, the Mazda RX-7 was one of the most popular and lauded mid-range sports cars. Mazda has since killed off both the rotary engine and the RX-7, although rumors of a successor continue to swirl.
