Its engine has a rotary example that uses three diverse chambers created between the rotor and rotor housing. Over the second childhood, the RX-7 was available with either a naturally aspirated or a turbocharged engine. In complete, three generations of the RX-7 were produced.
First-Generation Specifications
The RX-7 beginning reproduction maxim distinguished sales, with almost half a million sold worldwide. The early genesis had three leading series of cars. The Series 1 was the front assemblage of cars sold between 1979 and 1980.

The Series 2 cars were available with a naturally aspirated engine extremely as a turbo-equipped base. The pattern engine generated 146 horsepower, while the turbo base generated 189 horsepower. The 1986 RX-7 Turbo was named by Engine Trend as Motorcar of the Year, while the Turbo account mythical Motorcar and Chauffeur's top 10 record of cars in the 1987 replica year.The second-generation cars were powered by a 160-horsepower naturally aspirated engine that could be upgraded to produce 200 horsepower with the addition of a factory turbocharger.
