The Mazda RX-2 and RX-3, produced from 1971 to 1977, were two of the first iterations of Mazda's iconic rotary engine-powered vehicles. While the RX-2 and RX-3 shared a significant portion of their design and underpinnings, they differed in body style and intended market. The RX-2 was a coupe, primarily targeted towards the North American market, while the RX-3 was a more compact sedan, intended for the Japanese domestic market. Both cars were underpinned by a rotary engine, a unique technology that, in contrast to traditional piston engines, used a triangular rotor to generate power. This innovative technology, though complex, offered several advantages, including smooth operation, lightweight construction, and a high power-to-weight ratio. The RX-2 featured the 12A rotary engine, producing 110 hp, while the RX-3 was initially equipped with the smaller 10A engine, delivering around 90 hp. Both the RX-2 and RX-3 were celebrated for their sporty handling and impressive performance for their time. The RX-2's sleek coupe design and the RX-3's compact sedan body provided a sense of agility and were praised for their maneuverability. However, the rotary engine technology also presented some challenges, like fuel economy, reliability, and the need for regular maintenance. The rotary engine's unique design required specific lubrication and a more frequent rebuild compared to conventional engines. Despite these challenges, the RX-2 and RX-3 enjoyed a modest success, solidifying Mazda's reputation as a manufacturer of innovative and performance-oriented vehicles. Their legacy paved the way for future generations of rotary-powered Mazda sports cars, particularly the iconic RX-7, which further cemented the brand's image in the world of performance driving.
