The history of the vehicles with rotary engine immediately began very sporty with the Mazda Cosmo Sport 1968. Its engine was compared to the Ro-80-engine already developed much further, not necessarily in performance, but in durability. The chrome coating on the aluminum casing and a steel alloy on the aluminum side elements provided for a longer service life of the sealing surfaces. Even the successor RX 2 was exported to Europe. The maximum torque was now reached at a lower speed (5000 -> 3500 rpm). The RX 3 was the first in Germany purchasable rotary Mazda.
Up to the RX 4 there were in annual rhythm new Wankel vehicles. Thereafter, the development was slower. In the year after presentation of the four-door came out only body variants, a station wagon and the GT version shown above.               Top of page               Index
