The second generation RX-7 was introduced in 1985, seven years after the launch of the first generation RX-7 in 1978, which became Mazda's most popular sports car. Like the first-generation RX-7, the RX-7's most distinctive feature was its rotary engine, which was Mazda's only commercialized lightweight, compact, and low-vibration engine in the world. In developing the second generation RX-7, Mazda's engineering team established the "Sports Car Study Group" to study many cars in history. The team sought the ideal sports car that would transcend time and be loved by people throughout the world. The conclusion they reached was that the car should allow the driver to take independent control of the car and provide the driver with a "comfortable sense of tension. After unifying the development team's efforts in pursuit of a true sports car, Mazda pushed forward with the development of the new RX-7. Wind tunnel tests were conducted to dramatically improve aerodynamic performance, a new twin-scroll turbo engine was adopted, and the rear suspension was changed from the rigid suspension of the first generation to a higher-performance independent semi-trailing arm. The second generation RX-7 was finally released in 1985. At the time, the benchmark for FR-driven sports cars was the Porsche 944, and sports car freaks around the world shared the common understanding that the Porsche 944 was the king of FR sports cars. However, the newly released second-generation RX-7, while far less expensive, demonstrated performance that surpassed that of the Porsche 944, astonishing sports car freaks the world over. Thus, the second generation RX-7 has made a name for itself around the world and continues to be loved by passionate fans as a "true sports car" that inspires drivers all over the world.
