4. Mazda RX-7
The Mazda RX-7 is a sports car that was produced by the Japanese automaker Mazda from 1978 to 2002. The original RX-7 was a sports car with pop-up headlamps. The compact and lightweight Wankel rotary engine is situated slightly behind the front axle, a configuration marketed by Mazda as “front mid-engine”. It was offered as a two-seat coupé, with optional “occasional” rear seats in Japan, Australia, the United States, and other parts of the world. The models that conquered the 90s is the third generation of RX-7 which featured an updated body design compare to its predecessors. The sequential twin turbocharged system, introduced on this series in 1992, was a very complex piece of engineering. This engine can generate up to 27 horsepower. In Japan, sales were affected by the fact that this series RX-7 no longer complied with Japanese Government dimension regulations, and Japanese buyers were liable for yearly taxes for driving a wider car compared to previous generations. As the RX-7 was now considered an upper-level luxury sportscar due to the increased width dimensions, Mazda offered two smaller sports cars, the Eunos Roadster, and the Eunos Presso hatchback. Mazda has made several references to a revival of the RX-7 in various forms over the years since the RX-7 was discontinued. In November 2012, MX-5 program manager Nobuhiro Yamamoto indicated that Mazda was working on a 16X based RX-7, with 300 horsepower.
