Return of the Rotary: Mazda Plans Dorito Range-Extender for EV

Fans of the mythical rotary engine, a powerplant spoken of in hushed tones by Mazda fans ever since the company killed it off about a decade ago, will have something to celebrate after the Brussels Motor Show later this week.


Adding to its portfolio of electrification options, Mazda will be offering a fresh powertrain choice in its little MX-30 crossover, one which features an electric generator powered by a newly developed rotary engine.


Details are scant but what we do know comes from the company’s European branch which spilled the beans this morning. Potentially (and creatively) called the MX-30 R-EV, it’ll incorporate a rotary mill that will act as a range extender to the electric gubbins currently found in the MX-30. Alert readers will recall that model is rated at a slim 100 miles of range on a full charge, perhaps suitable for other markets but not ideal for many Americans.


It'll be interesting to learn if Mazda calls this mashup a plug-in hybrid or a range extender. Taken at face value from what we know today – which isn’t much – your author would categorize it as the latter since it sounds like the rotary will act as a generator for the electric powertrain and never directly power the wheels. A plug-in hybrid, as we know the term right now, can generally push itself down the road on internal combustion if necessary.


But we’ll learn all that once the car is revealed in Brussels. Packaging will also be interesting to see, though anyone who has peered under the hood of an MX-30 will know there are acres of space between the front tires – even with the EV guts in place.


There’s no official word if the MX-30 R-EV will be sold on this side of the pond. If offered, it could drive a stake through the heart of the all-electric MX-30 thanks to that car’s diminutive range numbers. The rotary range extender would help immensely in that regard. Whatever happens, rotary fans will be glad to know Mazda hasn't ended their fascination with the Dorito.

    We like the rotary because of how it feels to drive with the engine, not simply to have it running occasionally in the background at a steady-state 3,300rpm.

    I've always thought of the MX-30 more in line with the compliance cars of old(think E-golf or the electric focus), its designed to meet a regulatory requirement, not actually to sell cars. why they put so much work into a car like this makes zero sense to me.

  • SCE to AUX Here's a crazy thought - what if China decides to fully underwrite the 102.5% tariff?
  • 3-On-The-Tree They are hard to get in and out of. I also like the fact that they are still easy to work on with the old school push rod V8. My son’s 2016 Mustang GT exhaust came loose up in Tuscon so I put a harbor freight floor jack, two jack stands, tool box and two 2x4 in the back of the vette. So agreed it has decent room in the back for a sports car.
  • Kjhkjlhkjhkljh kljhjkhjklhkjh so what?? .. 7.5 billion is not even in the same hemisphere as the utterly stupid waste of money on semiconductor fabs to the tune of more than 100 billion for FABS that CANNOT COMPETE in a global economy and CANNOT MAKE THE US Independent from China or RUSSIA. we REQUIRE China for cpu grade silicon and RUSSIA/Ukraine for manufacturing NEON gas for cpus and gpus and other silicon based processors for cars, tvs, phones, cable boxes ETC... so even if we spend trillion $ .. we STILL have to ask china permission to buy the cpu grade silicon needed and then buy neon gas to process the wafers.. but we keep tossing intel/Taiwan tens of billions at a time like a bunch of idiots.Google > "mining-and-refining-pure-silicon-and-the-incredible-effort-it-takes-to-get-there" Google > "silicon production by country statista" Google > "low-on-gas-ukraine-invasion-chokes-supply-of-neon-needed-for-chipmaking"

  • 1995 SC This seems a bit tonedeaf.
