Mazda will debut the MX-30 R-EV on Jan 13. It will go on sale in the spring.

"The rotary returns. Mazda will debut the version of the MX-30 with a Wankel engine as a range extender on January 13 at the Brussels Motor Show. This model will be available in Europe in the spring.

Specific details about the engine's displacement and other mechanical details will likely arrive at the vehicle launch. Mazda previously said that the rotary runs at a constant speed to serve as a range extender for recharging the battery while on the road. The company touted this solution as combining the benefits of an EV with the range of a combustion-powered vehicle."
