When it comes to unique and unconventional car engines, rotary engines definitely make a mark. These engines, also known as Wankel engines, have a distinct design that sets them apart from traditional piston engines. Unlike the up-and-down motion of pistons in a typical engine, rotary engines use a spinning rotor to create power, resulting in a smooth and high-revving performance. This innovative technology has been utilized by a small number of car manufacturers throughout history, making these vehicles a rare and fascinating sight on the road.

One of the most iconic cars to use rotary engines is the Mazda RX-7. Introduced in 1978, the RX-7 quickly gained a reputation for its impressive performance and distinctive styling. With its lightweight design and powerful rotary engine, the RX-7 became a favorite among car enthusiasts. Another notable car that features a rotary engine is the Mazda RX-8, which was produced from 2003 to 2012. The RX-8 not only showcased Mazda’s dedication to innovative engineering but also offered a unique driving experience with its rev-happy rotary engine. While rotary engines may not be as common as piston engines, they continue to captivate car enthusiasts with their distinct sound, smooth power delivery, and thrilling performance.

The Legacy of Rotary Engines in Automotive History

What Cars Use Rotary Engines? Rotary engines, also known as Wankel engines, have a unique place in automotive history. Developed by German engineer Felix Wankel in the 1950s, rotary engines offer a different approach to combustion compared to traditional piston engines. These engines use rotors instead of pistons to generate power, resulting in a compact and lightweight design.

Mazda RX-7: The Iconic Rotary Sports Car

When it comes to rotary engines, the Mazda RX-7 is a name that immediately comes to mind. The RX-7 was first introduced in 1978 and became a cult favorite among sports car enthusiasts. It featured a compact yet powerful rotary engine that provided excellent performance and handling.

The RX-7 went through several generations, with each iteration improving upon the previous one. The third generation RX-7, produced from 1992 to 2002, is often regarded as the most iconic. It featured a twin-turbocharged rotary engine and a sleek, aerodynamic design that made it a standout in the sports car market.

Unfortunately, the RX-7 was discontinued in 2002, marking the end of an era for rotary-powered sports cars. However, its legacy lives on, and the RX-7 remains a symbol of the capabilities and potential of rotary engines.

Mazda RX-8: The Rotary Revival

Following the discontinuation of the RX-7, Mazda made another attempt at keeping the rotary engine alive with the RX-8. Introduced in 2003, the RX-8 offered a more practical approach, combining the power and performance of a rotary engine with a unique four-door design.

The RX-8 featured a naturally aspirated rotary engine, known as the Renesis engine, which provided a high-revving character and smooth power delivery. It also boasted a unique “freestyle” door configuration, with rear-hinged rear doors, offering easier access to the rear seats.

Although the RX-8 received praise for its handling and design, it faced challenges due to the rotary engine’s fuel efficiency and emissions. Despite Mazda’s efforts to improve the engine’s efficiency, the RX-8 was discontinued in 2012.

Nissan Cosmo: Pioneering Rotary Luxury

While Mazda took the spotlight with their rotary-powered sports cars, Nissan also played a role in the development and utilization of rotary engines. In 1967, Nissan introduced the Cosmo, a luxury coupe that featured a twin-rotor rotary engine.

The Nissan Cosmo showcased the potential of a rotary engine in a high-end, luxury vehicle. It offered a smooth and refined driving experience, combined with luxurious features such as air conditioning, power windows, and a plush interior.

However, the Cosmo faced challenges similar to other rotary-powered cars, including fuel consumption and emissions. As a result, Nissan discontinued the Cosmo in 1972, ending their venture into the world of rotary engines.

NSU Ro 80: The Forgotten Revolution

Before Mazda and Nissan, German automaker NSU made significant contributions to the development of rotary engines. In 1967, NSU released the Ro 80, a luxury sedan powered by a twin-rotor Wankel engine.

The Ro 80 was ahead of its time in terms of design and engineering. It featured aerodynamic styling, advanced technologies such as front-wheel drive and all-around disc brakes, and a comfortable interior. The smooth and quiet rotary engine added to its appeal.

However, the Ro 80 faced reliability issues with its rotary engine, leading to engine failures and subsequent damage to NSU’s reputation. Despite its pioneering design and features, the Ro 80’s production ended in 1977, and NSU was eventually absorbed by Audi.

Other Cars with Rotary Engines

In addition to Mazda, Nissan, and NSU, several other automakers have experimented with rotary engines in their vehicles.

  • Chevrolet produced the Chevrolet Aerovette concept car in the 1970s, featuring a mid-mounted rotary engine.
  • General Motors introduced the GMC L’Universelle concept van in 1970, powered by a two-rotor engine.
  • Toyota developed the Toyota 7, a sports prototype racing car that used a three-rotor Wankel engine.
  • Mercedes-Benz collaborated with NSU to create the C111 concept cars, which featured rotary engines.

While these vehicles never made it to full-scale production, they highlight the industry’s fascination with rotary engines and the potential they held for innovation.

The Revival of Rotary Engines

Although the era of rotary-powered cars has dwindled, there are still signs of a potential revival for these unique engines.

Mazda’s Rotary Engine Development

Mazda, the company most associated with rotary engines, has been exploring ways to bring them back to their lineup. In 2019, Mazda announced the development of a new rotary engine, known as the Skyactiv-R. According to Mazda, this new engine will prioritize fuel efficiency and emissions while still providing the unique characteristics of a rotary engine.

While specific details of Mazda’s plans for the Skyactiv-R are yet to be revealed, it’s a promising sign for rotary enthusiasts who eagerly await the return of a rotary-powered Mazda sports car.

Revolutionary Potential in Electric Vehicles

The unique design and characteristics of rotary engines also make them a potential candidate for hybrid and electric vehicles. The compact size and high power-to-weight ratio of rotary engines can make them an ideal range extender for electric cars.

Already, some companies are exploring the use of rotary engines in hybrid and electric powertrains to enhance performance and extend the driving range. This adaptation could help overcome some of the limitations of current battery technology and offer a viable solution for long-range electric vehicles.

In Conclusion

What Cars Use Rotary Engines? While the era of rotary-powered cars may be mostly in the past, the impact of these unique engines on automotive history remains significant. From the iconic Mazda RX-7 to the forgotten NSU Ro 80, rotary engines have left their mark on the industry.

Although challenges such as fuel efficiency and emissions led to the decline of rotary engines in mainstream vehicles, there are signs of a potential revival. Mazda’s continued development of the Skyactiv-R engine and the potential for rotary engines in hybrid and electric vehicles show that the story of rotary engines is far from over.
