Hailed by many as the most beautiful car ever to turn out of Japan, The Mazda RX-7 took seventeen years of development before it finally appeared on the streets in 1978.Without the conviction of an of Japanese motor engineers and manufacturers under the control of Kenichi Yamamoto, in the development of the Wankel or rotary engine, this strikingly intended, high end sports car, would not have happened.In 1961 the Japanese Company Toyo Kogyo, later to be renamed Mazda, registered from the patent proprietors NSU-Opel of Germany, the full rights to build a rotary engine.The Rotary engine was called after its designer Wankel and had no pistons or crankshaft as such, but consisted of a simple energy inserted rotor knife that span around a drive-shaft that was connected to a wheel differential for drive.In principle the rotary engine is much superior, through its simplicity in design, than a standard piston combustion engine, with significantly less moving parts to fail and strong drive energy output.Yamamoto’s team at Mazda set to work on developing an engine that would overcome the problems of reduction of pressure, fatigue, and the overheating of the rotor blades guidelines, that had restricted Opels success at developing the engineering in the 1950′s.After success with early in the day RX types the RX-2, RX-3 and RX-5 and despite economic problems at the organization, Mazda finally came up with the larger 12A engine which was fitted to the new Mark 1 RX-7 built from 1978 until 1980 and the series 2 built from 1981 to 1983.The Mazda Rx-7 was a seater plus two hardtop sports coupe, curvaceous and sleek and it immediately captured the imagination of the car world which internationally hailed instant design classic. The design of the vehicle was constructed entirely across the engine and exhaust configuration.A bi-rotor engine putting out what was seen as equivalent of just 550 bhp per windmill the 12A in the RX-7 was capable of speeds of over 130 mph and with high low-end torque achieved from 0 to 60 mph in just 6.3 seconds. Formally its bhp was just 100 horse power but given how light the automobile was, it was frequently called like driving a, the power to fat ratio gave it an output comparable to 230 bhp.Exhilarating to drive due to the smoothness inherent in the activity of the Wankel rotary engine, little vibration or shaking was felt at high engine speeds. When the 7000 rpm redline was approaching an alert was suited to the rev counter to advise the driver. When you exceeded it or did not take the alert the engine might cut out to protect the ceramic windmill methods from overheating.The car was high priced to perform, the engine eating around 20 miles to the quart but at half the cost of an and with all the cutting such as for instance electrical windows and sun-roofs, the RX-7 was wanted by young and old alike. Over 475,000 cars were sold with the original Mark 1 design.The RX-7 was seemed in advertisements, many TELEVISION shows and films.In Japan and loved by good and bad alike the car was used by the original Tokyo Drifters and neighborhood racers because of its handling and rate. In the UK a modified Turbo version of the 12A RX-7 created by Elford design held the unofficial document for the fastest night-time lap of the round M25 freeway that rings London, for 5 years.This turbo arrangement which employed the venturi principle to sell exhaust fumes for added boost, powered the car to rates of over 145 mph and was developed by Mazda into new 13B engine which powered the top end Series 3 generation model in Japan from 1984 to 1985.Various modified versions of the RX-7 were constructed for different areas around the world, with limited output and emissions control system in US versions and various custom treatment and design improvements for the European and domestic Japanese Market.Production of the Mazda RX-7 13B continued until 1988 with the convertible RX-7 Savannah and the new search Mark 2 model frequently known as the Series 4, which had sent some of the Mark 1 basic design lines and seemed more like its primary opponent, a Porsche 944.
