What are the models with rotary engines?

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.

As a performance car enthusiast, the most unforgettable rotary engine models are on the racetrack. The Mazda RX-7 FD is legendary, with its 1.3L twin-turbo delivering fierce thrust, razor-sharp cornering, and standing as a Japanese performance icon. Even more impressive is the 787B race car, the 1991 Le Mans champion whose roar shook the world. The RX-8, though more daily-drivable, revs up to a thrilling 9,000 rpm redline. These cars aren't just about raw horsepower—their simple, lightweight engine structure offers rapid response, perfect for drifting. However, they demand high maintenance, with prone-to-failure seals making them a technical challenge. The NSU Ro 80 attempted but failed. In short, choosing a rotary is like extreme sports—full of passion but requiring caution. Years after Mazda discontinued production, fans still await new surprises.

I've driven several rotary engine cars, mainly the Mazda series. Classic models include old cars like the Cosmo Sport, RX-2, and RX-3. The RX-7, the most popular, comes in three generations, a sleek rear-wheel-drive sports car. The RX-8 is the final model, with a more practical four-door design. Racing cars like the 787B are also quite famous. Pay attention to fuel consumption and limited parts availability during maintenance. This simple list should suffice.

From a practical perspective, the Mazda RX-8 is a great example of a rotary-powered car. Launched in 2003, its four-door design offers family-friendly convenience, with a spacious cabin and ample storage, making it suitable for daily commutes. Compared to the RX-7's two-door sports car layout, it strikes a better balance. However, rotary engines have drawbacks: high fuel consumption (averaging 10 liters per kilometer), expensive maintenance, and frequent sealing issues that can be troublesome. On the upside, they are lightweight, accelerate quickly, and are easy to handle. Other models like the Cosmo or older versions are mostly discontinued, making used purchases risky. It's advisable to choose an RX-8 with clear maintenance records and schedule regular engine checks. Ultimately, it's not the most economical choice but offers a unique driving experience. Mazda may explore range-extender systems or new rotary designs in the future.

Among rotary engine models, I'm interested in the possibility of a future revival. Mazda is a veteran, exploring new approaches after discontinuing the RX-7 and RX-8. News reports indicate they're developing a range-extended EV that uses the rotary as a generator to extend range, which is both eco-friendly and innovative. Historically, models like the Cosmo and racing technologies have proven significant reliability improvement potential. Other brands have made fewer attempts due to manufacturing challenges like high emissions and material limitations. But Mazda continues to make improvements, potentially combining it with hybrid technology. Choosing such a car isn't just for nostalgia, but also for its technological innovation breakthroughs.
