Rotary

Will we see a rotary engine used to recharge the batteries?

Mazda is currently working with a very flexible and efficient rotary hybrid platform.

Yes, it's official. It's really happening.

Since it looks like Mazda may very well revive the Wankel rotary engine as a range extender for electric cars, there's no better time to become reacquainted with the quirky internal-combustion engine. And there's hardly a better way to become reacquainted than by peering into a running rotary engine, which you can do with the video above.

Mazda's prepping a small rotary engine to serve as a range extender in an autonomous Toyota delivery vehicle.

There's evidence that it will happen.

It's still unlikely, but somewhat less so.

And like any dream, it probably won't be there when we wake up.

The stunning Mazda RX-Vision Concept appears to be just a tease.

Would you pay $79,000 for a Mazda? What if it could dance like Michael Jackson and sprint like Usain Bolt? Yes, the answer is definitely yes.

Jay Leno's Garage focuses on a '66 Bug with the heart of a 1990 Mazda RX-7.

It's not a Wankel, but it is installed in a go-kart. LiquidPiston's X Mini engine gets a micro-scale workout in this video.

Mazda's filing shows a new layout to the exhaust and intake ports of a turbocharged rotary. Maybe the RX-7 is really coming back.

Mazda's drivetrain and powertrain assistant manager wants the company's revived rotary engine to be turbocharged.

The Mazda RX-Vision concept at the Tokyo Motor Show points the way forward as the company tries to revive the rotary engine in an absolutely beautiful sports coupe. The brand hopes to have this gorgeous shape on the road someday.

Mazda isn't ready to give up on bringing the Wankel back and still has a team working to bring the design up to modern emissions and economy standards. A model using the updated mill isn't currently on the horizon, though.
