The Mazda RX3, a compact sports car produced from 1970 to 1978, marked a significant milestone in Mazda's history and in the development of rotary engine technology. Introduced as a successor to the Mazda R100, the RX3 initially offered a 1.0-liter 10A rotary engine generating 90 horsepower. This engine, paired with a four-speed manual transmission or an optional three-speed automatic, propelled the lightweight RX3 to respectable performance levels. Despite its compact size, the RX3 boasted a surprisingly spacious interior, offering comfortable seating for four adults. The car's design was clean and modern, with a distinctive sloping hood and a prominent front grille that showcased the rotary engine's unique character. As the years progressed, the RX3 underwent several updates, including the introduction of a larger 1.2-liter 12A engine in 1972, which offered increased power and torque.

The Mazda RX3 gained recognition for its nimble handling and responsive engine, making it a popular choice for both everyday driving and competitive motorsport. Its lightweight construction and potent rotary engine provided exhilarating performance, while the compact dimensions made it easy to maneuver through tight corners and urban streets. The RX3 also became a favorite among tuners and enthusiasts, who appreciated the potential for modifying the rotary engine to achieve substantial power increases. Over its production run, the RX3 proved to be a reliable and capable car, earning a loyal following among drivers who appreciated its unique character and performance. The RX3's success paved the way for future generations of Mazda rotary-powered sports cars, including the iconic RX-7, and cemented Mazda's reputation as a manufacturer of innovative and engaging automobiles.
