The Mazda RX-7, specifically the first-generation SA22C launched in 1978, established itself as a successful high-performance sports car in North America. Despite early setbacks caused by the 1973 oil shock and EPA scrutiny regarding rotary engine fuel efficiency, Mazda’s ‘Phoenix Project’ improved efficiency by roughly 40%, allowing the vehicle to offer high performance at a mass-market price.

In a more recent development, Mazda has accepted the return of a meticulously maintained RX-7 from Naoko Nishimoto, a Japanese driver who owned the vehicle for 25 years. Following Nishimoto’s decision to surrender her driver’s license, the manufacturer has committed to a full restoration of the car to use as a publicity vehicle to honor her story.
