This is a rear-wheel drive sports coupe - the only car in the world on which the Wankel rotary-piston engine was fitted as standard. The RX-7 (in Japan, the Savana RX-7) went on sale in 1978 as a 1979 model and was a real sensation. The first engine of this model was a rotary 12A of 1146 cm³, which worked with a 5-speed manual transmission. The engine and transmission were located on the undercarriage in such a way that the weight of the car was distributed between the front and rear axles in a 50/50 ratio. With a relatively long wheelbase - 242 cm - the weight of the car was quite small: 1084 kg (thanks to the lightweight compact body). The engine produced only 100 hp, but it allowed the car to accelerate to 100 km / h in 8.5 seconds. Brakes front disc / rear drum, wheels R13. It is noteworthy that the cars of the first years of release did not have a rear-view mirror on the passenger side.
