When the Mazda RX-8 ceases production the rotary engine goes away, as well.

The rotary engine is in for a revival, or so it might seem based on a tweet posted – in Japanese by the PR folks at Mazda headquarters in Hiroshima.

It suggests a “new model with next-generation rotary engine” is in the works, confirming a report by several months ago.

At the time, the senior executive on the maker’s new SkyActiv program, Kiyoshi Fujiwara, told TDB he was continuing to work on the Wankel engine almost as a skunk works project, even though it did not have the official corporate green light.  (For the full story, Click Here.)

Now, it appears, the next-gen rotary program is on the official program, though the Mazda posting did not provide any details, according to our friends at

The rotary engine has been a favorite for many tech aficionados since the 1960s, when it made its first appearance in Europe in an NSU and, shortly afterwards a Mazda.  In fact, it appeared that the Wankel would become an automotive mainstay, with manufacturers as diverse as General Motors and AMC planning to put it into production.

The Mazda Kabura concept makes its debut in Detroit.

The rotary engine is the powertrain of the future – and always will be, declares the engineers who have spent frustrating decades trying to overcome the once-promising Wankel engine’s drawbacks.

Small, light and powerful, the rotary seemed destined for glory, with makers such as General Motors, Mazda and American Motors among the many manufacturers committed to using the engine back in the 1970s.  But then the first Mideast energy crisis struck and all but Mazda were forced to abandon the Wankel due to its relatively poor fuel economy.

The Inside Story!

Over the years, Mazda has scaled back rotary applications but never abandoned the technology – and now, the Japanese maker may have come up with an intriguing solution, using a laser ignition system, instead of conventional spark plugs to boost the Wankel’s fuel efficiency.

The British magazine AutoCar quotes a “senior,” albeit unidentified Mazda engineer involved with the ongoing development of Mazda’s next-generation rotary, known as the 16X Renesis.
