all the RX-3's built, the coupe exceeded 50 percent of total sale – all facts which influenced the design profile of the RX-7. The rotary engine had financial advantages to Japanese consumers in that the engine displacement remained below 1.5 litres, a significant determination when paying the Japanese annual road tax which kept the obligation affordable to most buyers, while having more power than the traditional inline engines. Racing The Savanna/RX-3 was the next Mazda racing entry, following up the success of the Cosmo and Familia Rotary. The Savanna debuted with a win at the September, 1971 "Fuji 500" race. The cars battled with Nissan's Skyline on the Japanese Grand Prix in 1972, winning the touring car category there and preventing the GT-R from winning 50 consecutive races. The cars continued to be competitive, claiming over 100 victories by 1976. A special edition "V100" model was released for sale in Japan to commemorate this occasion. Many vehicles continue in club racing to this day. In Australia the RX-3 proved very successful both on and off the race track. One of many RX-3s racing in the 1975 Bathurst 1000 caused more than a worried look after placing fifth outright and 1st in its class for the second consecutive year after its initial class win in 1974. The RX-3 dominated the class C in 1975 holding 4 of the top 5 positions. In North America, the RX-3 had much success in SCCA and IMSA competition. Many RX-3s are still competing and one in particular is the SCCA Super Production car driven by Irish driver John Cummins. The RX-3 was replaced with the Mazda RX-4.
