Mazda Shatters the RX Dream: Why the Rotary Engine Has No Future

The Japanese brand prioritises key investments and puts the comeback of its iconic sports car on hold.

The end of an era for rotary-engine enthusiasts

Mazda has once again extinguished hopes for the legendary rotary engine, a technical icon that shaped generations and once seemed close to returning through projects like the RX Vision or the recent Iconic SP. However, industrial reality has taken over. The company, which stopped building Wankel-powered sports cars in 2012, now acknowledges that it simply cannot justify the massive financial effort required to bring a modern RX to production, especially when its sales volume is far below that of rivals such as BMW. For a mid-size manufacturer, betting big on a niche sports car is a luxury it cannot afford.

The rotary engine made a symbolic comeback in 2023, although only as a generator in the MX-30 R-EV, with no mechanical connection to the wheels. A similar approach was shown later that same year with the Iconic SP concept, but Mazda has made it clear that this does not signal the return of the RX. CTO Ryuichi Umeshita openly admits that the project could be executed from a technical standpoint, but also confirms that “the only issue is financial”, hinting that the dream of a rotary coupé remains far from reality.

Mazda now has far more urgent priorities. The brand is developing its first dedicated electric platform, a new hybrid system, and a 2.5-litre Skyactiv-Z petrol engine designed to replace today’s four-cylinder Skyactiv-G and Skyactiv-X units. Even the development of the next MX-5 –already confirmed and expected to feature a larger engine– demands significant resources. Trying to revive the RX project at the same time simply clashes with Mazda’s electrification roadmap and with the increasingly strict emissions rules worldwide.

From an enthusiast’s perspective, it seems wiser for Mazda to concentrate on the MX-5, the world’s best-selling two-seater sports car and the brand’s spiritual core. Repeatedly reviving the dream of an RX only dilutes engineering resources that could be better invested in models that truly sustain the company. Even ideas for a future coupé using Mazda’s inline-six engine have reportedly lost momentum due to a lack of a solid business case.

In the end, Mazda isn’t completely closing the door on the rotary engine, but it acknowledges that reconnecting a rotary to the wheels would be extremely challenging, as it would need to operate across a much wider rev range. The development team was reinstated in 2024, yet the immediate priority is improving emissions and efficiency. With so many major projects underway –new hybrids, new EVs and the upcoming MX-5– the conclusion is inevitable: Mazda must choose logic over nostalgia. And the rotary engine, as painful as it is for fans, will have to wait.
