What are the models with rotary engines?
2 Answers
Models with rotary engines include the Mazda RX7 and Mazda RX8. The operational characteristics of a rotary engine are as follows: the center of the triangular rotor revolves around the output shaft's center while the triangular rotor itself rotates around its own center. As the triangular rotor turns, the internal gear ring centered on the rotor meshes with a gear fixed on the cylinder block (which does not rotate), with a gear ratio of 3:2 between the internal gear ring and the gear. The working principle of a rotary engine involves directly converting the combustion expansion force of the fuel-air mixture into driving torque. Compared to reciprocating engines, rotary engines eliminate useless linear motion, resulting in a more compact size, lighter weight, and lower vibration and noise levels for the same power output, offering significant advantages.
When it comes to rotary engine cars, I love talking about the classic models. Mazda is undoubtedly the pioneer, starting with the 1967 Cosmo Sport—that car was way ahead of its time, with its distinctive rotary engine sound. Then came the RX-2 and RX-3 in the 1970s, proving that even daily drivers could be this cool, offering quick acceleration and minimal maintenance. The RX-7 became a hit in the 1980s, especially the FC and FD versions—rear-wheel-drive sports cars with sleek lines that turned heads in the city. The RX-8 arrived in 2000, adding four doors for practicality, delivering thrilling high-revving performance but at the cost of higher fuel consumption. Let’s not forget race cars like the 787B, which clinched victory at the 24 Hours of Le Mans. Mazda eventually discontinued production mainly due to high costs and emission issues, but these cars are now hot commodities in the used market. Recent news suggests Mazda might revive the rotary as a range extender for electric vehicles, sparking excitement for its return. These cars represent innovation and spirit—though niche, their charm is undeniable.
