Mazda RX-7 The Rotary Engine Sports Car
The Mazda RX-7 is a sports car that was produced in Japan beginning in'78 and ending in 2002. The most unique feature of the car was its featuring of a rotary or Wankel engine. The RX-7 was a replacement for the RX-3 and eventually was the only rotary engine vehicle produced by Mazda other than the Cosmo.
The rotary engine in the first of the RX-7s was only 1150 cc. The motor featured a twin rotor engine and the vehicle was rear wheel drive. Wankel invented his engine in Germany, but Mazda is one of the few car manufacturers to ever successfully use these engines. The company faced an uphill climb as they went through the fuel crisis of the'70s with the engine that burned more fuel.
Rotary engines are lighter in weight that other gasoline engines. They can be built from aluminum and are popular in use of air craft, but their use in land vehicles has been very limited. Mazda owners often brag about the smooth running rotary engines.
The rotary engines were found to be easily modified to meet air emission standards without catalytic converters. However, this conversion caused them to use even more fuel. By'84, Mazda offered a fuel economy of 29 highway and' city. In the RX-8 replacement for the RX-7 the fuel economy is comparable to other vehicles of the same size and weight class.
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.
In the later part of the 80's Mazda redesigned the RX-7 and styled it to look like the popular Porsche. In'88, they introduced the RX-7 convertible who's production continued until'92. While it was being produced, the convertible was rated as the best convertible that had ever been produced.
The RX-7 started its third generation in'92, but sales of the RX-7 stopped in the United States sometime in'95. Only a limited number of RX-7s were shipped to the Stated during'92, but the vehicle continued to be sold in several other countries around the world.
Worldwide Mazda introduced the RX-8 to replace the RX-7. The United States saw their first models in 2001 at auto shows, however sales were delayed until 2004. The RX-8 still uses Mazda's tradition of rotary engines. Seating in the RX-8, however is designed for four persons. - 21392
