Mazda Plotting EV With Rotary Range Extender

A new rotary-powered Mazda has been on the table for many years, but the Japanese manufacturer could also employ a rotary engine for their first electric vehicle, as a range extender.

Speaking with AutoExpress on the sidelines of the Geneva Motor Show, Mazda’s R&D chief, Matsuhiro Tanaka, refused to outright confirm it, but said that it’s a possibility.

Something like that was in existence, but I can’t go into detail. Both performance and economy are possible with rotary. It’s very stable and quiet at standard revolutions, so some potential exists for that.

Tanaka didn’t go into detail about its size either, but the electrified Mazda is expected to slot somewhere between the sub-compact and compact segments, which means that it could take on cars such as the Renault Zoe and Nissan Leaf, even if its European launch hasn’t been confirmed yet.

A small car is best for an EV, because bigger vehicles get too heavy with bigger batteries, and that doesn’t make sense for Mazda” Tanaka said. “If we put in heavy batteries, we need to do the opposite with the total weight. We are going to develop a new material technology in the future [for this].

As far as its appearance goes, the green Mazda would use the brand’s latest design language, which can be seen on the new CX-5 and RX Vision Concept. If everything goes as planned, it could be introduced in 2019, as a previous report suggested.

Mazda’s range of electrified vehicles will reportedly increase from 2021 with a lineup of PHEVs, which, could benefit from Toyota’s expertise in the field, just like the current Japan-only Mazda3 hybrid.

    A stirling engine would be much better than a rotary if it’s used only for battery filling… Car makers, hear this ?

    mazda is currently making most beautiful designs…

    • Just not sure the new CX5 is better looking than previous. But the mazda 6 since the facelift might be the best looking sedan by far. Not liking it, is not liking car design (or be camry, prius… lover maybe).

    Well they’ve been talking about that for years now. Time to get into action. And please, give the Mazda2 a proper facelift to made the rear look more like the concept

  • Eythan Aldrich

    Hmmmm……….I’m watching you Mazda

    Everytime I see that Hazumi concept, I just drool. Every super mini in the world should look this good. I hope the styling carries over to the next Mazda 3.

    Rotary rumors never seem to stop. Maybe this one will actually come true, fingers crossed. I think it’s safe to say Mazda’s design would make other electric cars like the Leaf look even worse than they already do (if that’s possible).
