The Mazda RX-7 is a sports car produced by the Japanese automaker Mazda from 1978 to 2002. The original Mazda RX-7 featured a 1146 cc (69.9 cu in) twin-rotor Wankel engine and a front- engine, rear- drive layout. The Mazda RX-7 replaced the RX- 3 (both were sold in Japan as the Savanna) and subsequently replaced all other Mazda rotary engine cars, with the exception of the Cosmo.

Introduced the Series 5 (1989-1992) updated styling and better engine management, as well as lighter rotors and a higher compression ratio, 9.7:1 for the naturally aspirated model, and 9.0:1 for the turbo model. The naturally aspirated Series 5 FC 160 hp (119 kW), while the Series 5 Turbo made ​​200 hp / 205 hp (147 kW).
The second generation Mazda RX-7 , still known as the Savanna Mazda RX-7 in Japan, presents a complete redesign reminiscent of the Porsche 944 and Porsche 924th Mazda stylists, led by Chief Project Engineer Akio focused Uchiyama, on the Porsche 944 for their inspiration in designing the FC because the new car was set up mainly for the American market, where most of the generation RX purchased-7. This strategy was chosen after Uchiyama and others on the design team spent time in the United States studying owners of earlier Mazda RX-7 and other sports cars popular in the American market. The Porsche 944 was selling particularly well at the time and type provided clues as to what might find appealing sports car enthusiasts in the future, the style and the Mazda RX-7 team. While SA22/FB was a pure sports car, the FC tended toward sports- smooth tourer trends of its time.
The third generation of the Mazda RX-7 FD (with FD3S for Japan and for the U.S. JM1FD VIN), featured an updated body design. The 13B- REW was the dual sequential turbocharger- mass produced first export from Japan, increased power to 255 hp (188 kW, 252 hp) in 1993 and finally 280 PS (206 kW, 276 hp), if production in Japan is not more in 2002. The FD Mazda RX-7 was Motor Trend's Import Car of the Year. When Playboy first review of the FD Mazda RX-7 in 1993 proved that the same number as the new Dodge Viper. In this issue, Playboy declared the Mazda RX-7 the better of the two cars. He earned Playboy Car of the Year for 1993.

June 2007 Road & Track proclaimed " The ace in the hole is the Mazda RX-7, a car once thought to be the purest of cars, most exciting sports in the world. "
The sequential twin turbocharged system was a very complex piece of engineering, developed with the aid of Hitachi and previously on the domestic Cosmo series (JC Cosmo = 90-95) were used. The system consists of two small turbochargers, an offer from the thrust at low speeds. The second unit was on standby until the upper half of the rev range for maximum acceleration. The first turbocharger delivers 10 psi (0.7 bar) of 1800 rpm pulse activated and the second at 4000 rpm and turbocharger also provided 10 psi. The change process at 4500 rpm, 8 psi (0.6 bar) occurred was mild, and linear acceleration and broad torque curve across the entire engine speed range.
