Mazda Savanna RX-3 Racing (S102A)
The Mazda Savanna RX-3, known as RX-3 in export markets, represented Mazda's commitment to rotary engine technology in a compact sports sedan package. The Racing variant (S102A chassis) featured the 12A twin-rotor Wankel engine displacing 1,146cc (equivalent to approximately 2.3L in conventional displacement) producing 105 horsepower at 7,000 RPM. The rotary's compact size, smooth power delivery, and high-revving nature made it exceptional for motorsports. Lightweight construction at just 890 kg created an excellent power-to-weight ratio. The simple live rear axle with coil springs and front MacPherson struts provided predictable handling. Four-wheel disc brakes were unusual for the era in this class. The two-door coupe body style offered attractive styling with crisp lines and functional design. Mazda's racing success with the RX-3 was legendary - dominating touring car championships in multiple countries and establishing rotary credibility. The RX-3 won the prestigious 1979 Spa 24 Hours in Belgium. Its combination of lightweight construction, rotary power, and racing success made it highly desirable. Today, clean examples are extremely rare, with values climbing to $40,000+ for pristine models. The RX-3 represents an important chapter in rotary history between the Cosmo Sport and RX-7.
