rally2727In October 1991, the FD3S RX-7 was announced by the second full model change, and sales began in December of the same year. Taking this full model change as an opportunity, the name of "Savannah" that lasted for 20 years from 1971 was removed, and it was released as "Ẽfini RX-7" under the name of the dealer series "Ẽfini" at that time. Later, the Ẽfini store was integrated with the Eunos store, and the car name was changed to "Mazda RX-7."
The engine output was 255ps for the 13B rotary engine equipped with the sequential twin turbo, but the power-to-weight ratio (weight / output ratio) of the initial 255ps car was less than 5kg / ps. Later, the engine output was improved, reaching 265ps (MT model) with a minor change in January 1996 and 280ps with a minor change in January 1999, and the power-to-weight ratio for some models was 6.11kg/kW (4.50kg/ps).
Since the company's Eunos Cosmo discontinued production in 1996, the RX-7 will be the only mass-produced vehicle equipped with a rotary engine in the world. The RX-7 continued to be developed as a vehicle with the concept of "pure sports", such as reducing the weight of the car body and increasing the output of the engine, but the demand for sports cars in the Japanese and North American markets declined, and The RX-7 ended its 25-year history with production discontinued in August 2002 and discontinued in April 2003 due to reasons such as a deadlock in environmental measures for turbocharged rotary engines.
