The Mazda R100 used the chassis from the Familia and the Wankel engine Mazda Wankel engine engine similar to the one used in the Cosmo Sport Series II. It was a 2 door 2+2 coupé and was produced from 1968 to 1973. It was also known as the Familia Presto Rotary and was quite ordinary except for its powerplant. Power was rated at just 100 hp (70 kW) due to a small Carburetor (thus the "R100" name).

United States


The R100 was one of the first cars imported into the United States for the new Mazda Motors of America, sold in model years 1971 and 1972. It was a surprising hit with the American public, though sales were limited to some Northwestern states initially[1].

Racing


Following on the success of the Cosmo Sports at Nürburgring in 1968, Mazda decided to race another rotary car. The Familia Rotary Coupé won its first outing, at the Grand Prix of Singapore, in April, 1969.

Next, the company took on the Gran Turismo endurance challenge at Circuit de Spa-Francorchamps, the Spa 24 Hours. For 1969 and 1970, Mazda entered a pair of Familia Rotary Coupés. The cars came fifth and sixth the first year after a quartet of Porsche 911. The next year, four Familias were present, battling with BMW Alpina, and Alfa Romeo for the podium. This time, three of the Mazdas were retired, with the fourth claiming the fifth position.

The Familia also placed fifth at the Marathon de la Route at Nürburgring in 1969, the same race that the Cosmo had bowed at the previous year. Finally, Mazda took the Familia home for the Suzuka Circuit All-Japan Grand Cup, where it won easily.

For 1970, the Familia placed eighth at the RAC Tourist Trophy in June, fourth at the West German Touring Car race in July, and fifth at Spa, as mentioned above.

Mazda also turned its attention to 24 Hours of Le Mans in 1970 with rotary-powered prototypes. The company would finally win that race 21 years later with the Mazda 787.
