Rotor engine is more cattle. Does China have a rotary engine car?

After decades of relentless research and perseverance, the rotary engine has become a signature technology for Mazda. There's no doubt that Mazda played a pivotal role in bringing this unique engine to practical use. From the iconic Cosmo to the legendary RX-7 and the Le Mans-winning 787B, the rotor engine has been at the heart of many unforgettable moments in Mazda’s history. It’s no surprise that when people think of rotary engines, Mazda often comes to mind. However, the story of the rotary engine isn’t solely Mazda’s—its origins trace back to German engineer Felix Wankel and the NSU company. Together, they built upon previous research, solved critical technical challenges, and successfully developed the first rotary engine. The technology was not only a breakthrough but also a huge business opportunity. Many automakers, including Mercedes-Benz and Toyota, showed interest, but the high fuel consumption, development costs, and inherent design flaws led most to abandon it. Yet, Mazda, a relatively small and less-known company at the time, saw potential and secured the rights to develop the technology. Today, only Mazda continues to refine and use the rotary engine. In 1957, Felix Wankel filed a patent for the rotary piston engine. After years of testing, the world’s first car with a rotary engine—the NSU Spider—was launched in 1964. It featured a compact 498cc single-rotor engine placed at the rear, offering a high power-to-volume ratio due to the engine’s unique operating characteristics. The Spider produced 37 kW of power and came with a 4-speed manual transmission. Despite its small size, it weighed just 700 kg, allowing it to accelerate from 0 to 100 km/h in 14.5 seconds. Although the Spider had issues with fuel efficiency, durability, and maintenance, it captured the imagination of enthusiasts with its innovative design. It sold over 2,300 units during its three-year production run, marking an early attempt at commercializing the rotary engine—though not entirely successful. Following the Spider, NSU introduced the Ro80 in 1967, another rotary-powered vehicle. The Ro80 featured a sleek, futuristic design and advanced features like four-wheel disc brakes, independent suspension, and power steering—many of which are now standard in modern cars. Its 995cc dual-rotor engine delivered 84 kW of power and was paired with an automatic manual transmission (AMT), achieving a top speed of 180 km/h. Despite its performance and technological appeal, the Ro80 struggled with the same durability issues as its predecessor. NSU had to improve sealing materials and offer extended warranties, which contributed to financial difficulties. In 1969, NSU was acquired by Volkswagen and eventually merged into Audi. While other manufacturers moved on, Mazda continued to invest in the rotary engine, turning it into a symbol of innovation and performance. Today, it remains one of the few companies still pushing the boundaries of this remarkable technology.
