When it comes to the Wankel rotary engine, no one does not think of the Mazda brand from Japan with these excellent sports cars. Many different models of Mazda, especially in the 80s, 90s of the 20th century and the beginning of the 21st century, were equipped with this type of engine. The most famous of these is probably the RX sports car line, with the most prominent being the RX-7 with three generations and being on the market for more than twenty years. First launched in 1978 and discontinued in 2002, the Mazda RX-7 has three generations of its own and more than 800,000 units were sold. With the RX-7, the Wankel rotary engine was upgraded and became more popular at the time and made the car more special than its competitors in its segment. Judging from the parameters, it can be seen that the RX-7 is not really outstanding, however, bringing a different driving feel, lightweight when using a small engine block and especially the sound coming from the Wankel engine has made many cars enthusiasts “dead tired” with it.
RX-7 “FB”: 1978 – 1985
First launched in 1978 and a European market a year later, the Mazda RX-7 “FB” is the first generation of this legendary sports car. With the use of a 1.1 liter Wankel engine, the weight of the car is kept at just over 1,000 kg but still has a capacity of 100 to 133 horsepower. At that time, Mazda even advertised its car with Porsche 944 and of course, the car from Japan was sold the almost half cheaper and almost equivalent performance.
With the engine placed in the front – middle and rear-wheel drive and the weight distribution ratio is almost perfect, the car easily shows the ability to operate emotionally. It offers excellent driving experience, and the ability to connect the driver’s impression to the vehicle.
Later, the RX-7 became one of the best sports cars in its price range when the turbocharged version was launched in Japan with 158 horsepower and the 13B engine version, 1.3 liter capacity with a fuel injection system. This generation is also the most successful generation of this model when selling more than 470,000 units.
Mazda RX-7 “FC”: 1986 – 1992
The second generation of the Mazda RX-7 has an upgraded design but has similarities with the rival Porsche from Germany. Along with that, many upgrades were made to provide a better performance, including the new turbocharger and DTSS (Dynamic Tracking Suspension System) suspension. Mazda then realized that this Wankel engine block was very suitable for the turbocharger, especially with its characteristic exhaust system. These upgrades also help improve torque at some point.
In this generation, Mazda equips the RX-7 turbocharged 1.3-liter 13B engine as standard, producing a maximum capacity of 148 horsepower. Later, the turbocharged version was released with 177 horsepower and 197 horsepower. In the most powerful version, the Mazda RX-7 “FC” is capable of accelerating to 100 km / h in 6 seconds, reaching a top speed of 240 km / h.
The second generation has sales of more than 270,000 units and this is also the only generation of this model to own a convertible configuration besides hardtop.
Mazda RX-7 “FD”: 1992 – 2002
In the last generation, Mazda RX-7 is widely known, becoming a symbol of the JDM line with the Wankel rotary engine. In this generation, Mazda equips 13B twin-turbo engine, producing maximum power up to 236 horsepower. In addition to power, the car is also known for its most impressive ability with a maximum speed of 250 km / h, accelerating to 100 km / h in 5.3 seconds and is the car with the best driving feel.
At that time, the car weighed only 1,300 kg and seemed to be praised by car enthusiasts as being the best sports car on the market. Unfortunately, by 1996, Mazda had to stop selling this car in the European market because of emissions. The company continued to sell this model in other markets until 2002 with the final version with 276 horsepower.
Up to that time, 68,000 RX-7 “FD” were sold. The Mazda RX-7 was replaced by the RX-8, but it was not as successful as its predecessor.
As a car company that always supports the Wankel rotary engine despite the whole world turning away from this engine, but Mazda at this time is no longer used commercially this type of engine. However, in the future, with the help of electric motors, it is likely that the company will bring this engine block into the production line.
