Produced between the years of’78 and 2002, the Mazda RX-7 was a Japanese sports car. One unique feature of the sports car was its feature of the Wankel or rotary engine. Mazda used the RX-7 to replace the RX-3 and it eventually was the replacement for all of their rotary engines other than the Cosmo.
The first RX-7 only had a 1150 cc engine. The rotary engine featured twin rotors and the vehicle was a rear wheel drive car. The rotary engine had been developed in Germany many years earlier, but Mazda is one of the few auto manufacturers to successfully use the technology in a widely produced vehicle. One drawback of the engine is that it uses more fuel than the piston engine. This cause several problems for Mazda in the 70s oil crisis.
Rotary engines are light weight in their construction. This gave the RX-7 a feeling of more power with a smaller engine. The engines also run smoother that a comparable piston engine.
While the rotary engine is easier to modify to meet fuel emissions standards, Mazda had problems with these modifications causing the engine to require even more fuel. Fortunately, by’84, the fuel economy was up to an estimated 29 mpg on the highway and’ mpg for the city. In the RX-8, fuel economy is comparable to other vehicles of its size and weight.
The RX-7 was initially introduced as a sports coupe. The coupe offered a mid mounted engine that offered great stability. In America, it was offered as a two seat coupe and in Japan some rear seat units were introduced. In the States, there was an option for dealer installed rear seats.
The second generation RX-7 introduced in the mid to late 80s was styled to look much like a Porsche. Additionally, the RX-7 convertible was introduced in’88. Production of the convertible continued until’92. The convertible was rated as one of the best convertibles ever produced.
In’92 the third generation RX-7 was introduced and the sales of the RX-7 stopped during’95 when only a limited number of the Mazda RX-7s were shipped to the United States dealers for sale. Sales of the vehicle continued in other parts of the world until 2002.
The RX-8 has been introduced by Mazda to replace the RX-7. The RX-8 was first seen in car shows in 2001 but not sold in the United States until 2004. Standard equipment in the RX-8 are seating for four. Mazda continues to use the rotary engine in the RX-8.
