Considered by many as the most beautiful car ever out of Japan, the Mazda RX-7 was seventeen years of development before it finally appeared on the streets in 1978.

Without the perseverance of a team of automotive engineers and designers under the direction of Japan Kenichi Yamamoto, the development of the Wankel engine or rotary, this amazing design, high performance sports car, would never have happened.

In 1961, the Japanese Society Toyo Kogyo, which later would be renamed Mazda, under license from the patent holders NSU-Opel in Germany, all the rights to develop a new rotary engine.

Rotary engine was named after its inventor, Wankel and had no pistons or crankshaft as such, but consisted of a single fuel injection wing that extends around a central shaft which was connected to a rear differential for driving.

In theory, a rotary engine is superior due to its simplicity of design compared to conventional internal combustion engine, much less moving parts to go wrong, and the direct transmission of power.

Yamamoto's team set to work on the development of the Mazda rotary engine, which would eliminate the problems of loss of compression, discharging and overheating of the tips of the rotor blades, which was limited to the successful Opel is developing the technology in 1950.

After the success of previous models RX RX-2 RX-3 and RX-5, and despite the economic problems in the company, Mazda has finally arrived to the largest motor 12A was mounted on the new RX-1 Mark 7 is constructed from 1978 to 1980 and Series 2 are built from 1981 and 1983.

The Mazda RX-7 was a hardtop coupe two-seater and two curved, aerodynamic and immediately captured the imagination of the automotive world that is usually considered a classic design. The design of the car was built entirely on the engine and exhaust configuration.

BI-rotor engine putting out what was seen as responsible for only 550 horses Fri 12A rotor in the RX-7 was capable of speeds over 130 mph and a high torque at low engine speeds to achieve 0-60 mph in 6.3 seconds only. Officially, the BHP has only 100 hp, but when you consider how light the car was, was often described as a skateboard guide, power to weight is given power to 230 hp.

Exciting to drive because of the sweetness inherent in the movement of the Wankel engine has little vibration or tremor felt at high engine speeds. An alarm was installed on the tachometer to warn the driver when the 7000 rpm redline was approaching. If you passed or not take account of the alarm, the engine would cut to protect the ends of ceramic rotor overheating.

The car was very expensive to run the engine to consume about 20 miles per gallon, but at half the price of a Porsche and all the cuts, such as windows and roofs, the RX-7 was requested by the young and old. More than 475,000 cars were sold with the original design of the Mark 1.

RX-7 was loved by so many good and bad, and has appeared in numerous television shows, commercials and films.

In Japan, the car was taken by original Drifters Tokyo street racing because of its speed and handling. In the UK, a modified version of the 12A Turbo RX-7 built by Elford Engineering had the unofficial record of the night time around the best of the M25 circular ringing in London for 5 years.

This turbo setup that used the Venturi principle to recycle the exhaust gas for extra lift, run the car at speeds exceeding 145 km / h and was adopted by the new Mazda 13B engine that fueled the series Top end 3 of the production model in Japan from 1984 to 1985.

Various modified versions of the RX-7 is produced for different markets around the world, with a limited production and emission control system in the U.S. versions and miscellaneous injections and design changes for the European and Japanese market.

The production of the Mazda RX-7 13, continued until 1988 with the RX-7 convertible Savannah and the new look of the Mark 2 model is often referred to as the series 4, which sent some of the design lines and classic Mark 1 more like its main competitor, a Porsche 944.
