While the first generation RX-7 has been active in races around the world, it has also gained popularity as a casual category called secretary car used by women who work as intended in North America to commute. Even at that price, it was less than half the Porsche that many Americans wanted, and yet the performance was close to Porsche. In the latter half of the model, the yen's appreciation advanced further and the local center price exceeded 10,000 dollars, but it still maintained annual sales of about 50,000 units.

Even so, customers rushed to the dealers to get the car even with $1,000 premium. After all, the release price in North America was 6995 dollars, which was far beyond the target. In the spring of 1978, which is about to be released, the price will drop below 200 yen for a moment. However, around this time, the yen appreciated rapidly. If converted into Japanese yen, it was about 1.2 million yen, and was close to the vehicle price of the RX-7 actually sold in Japan. The exchange rate at that time was around 300 yen per dollar. When the first RX-7 was planned in 1975, the goal was to sell it for under $4,000. It gained a lot of attention as soon as it appeared, and it was popular enough to be traded with a premium in the North American market. In 1978, the SA22C type first Savanna RX-7, a rotary engine car that was born. Actually it’s only possible with a rotary engine. That was possible with a lightweight and compact rotary engine. As a result, unlike Japan at the time when sports cars were even equated with gangs, in the North American market, young and old men and women were interested in a wide range of sports cars, and if there was an attractive sports car at a reasonable price, they would use it for commuting to work or school. The trigger was a thorough market research in North America. The decisive factor for the revival from that point was the RX-7, which was later called the rotary rocket. The development team made an effort to improve fuel efficiency and achieved a 40% improvement in just a few years, but it was no longer possible to equip a utility vehicle with a rotary engine. The oil shock broke out in 1973, and the rotary engine cars labeled "Gas Eating" stopped selling quickly. Unfortunately, the misfortune hit when the company quickly cleared the exhaust gas regulations and expanded its sales performance in the North American market.
