Mazda RX-7 history: From fuel crisis to North American success

The first-generation Mazda Savanna RX-7 (SA22C), launched in 1978, became a massive success in the North American market despite early challenges. Following the 1973 oil shock and criticism from the US Environmental Protection Agency (EPA) regarding the fuel efficiency of rotary engines, Mazda faced significant setbacks in its primary export market.

To recover, Mazda engineers initiated the ‘Phoenix Project,’ which successfully improved fuel efficiency by approximately 40%. Market research in the United States revealed a demand for high-performance sports cars at affordable prices, a demographic that differed from the Japanese market where sports cars faced social stigma.

By offering Porsche-level performance at a mass-market price point—approximately $6,995 in North America—the RX-7 achieved explosive popularity, leading to significant backorders and premium resale values. The vehicle featured a front-midship layout and a 2+2 seating arrangement for the Japanese market to meet local regulatory requirements.
