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

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.

2ACL My girlfriend currently drives a 2018 SE hatch. Automatic, but I've been handling the fluid services (looking to do another along with the filter soon) and it's been a solid runner for her. My only issue with its dynamics is the transmission's gingerly kick down out of corners (the SEL is the lowest trim that offers manual control functionality IIRC). Otherwise, none of the quirks that've blighted the Powershift's reputation have manifested.A stick would drastically extend its life expectancy. I know she isn't as committed to stick life though, which influenced my approval.
MaintenanceCosts GM hasn't put any effort into any Cadillacs except the Blackwings and the electrics. They're getting out what they put in. Pretty simple, really.The XT4/5/6 are all just slightly up-styled versions of Chevy products, but priced as if they were on dedicated luxury platforms like the BMW and Benz competitors to the larger two. The XT6 is especially embarrassing.Even the Escalade is just a Tahoe/Suburban with a few trick design touches and a halfhearted materials upgrade. The good news for Cadillac is that the Tahoe/Suburban are seen as upscale enough that a half-a$s upgrade to them can be a legitimate luxury car.Where's the "gotta have it" factor? Where are the dazzling interior designs? Where's the swagger? Until those show up the brand is just a set of memories.
Dwford The problem with Cadillac is that the only Cadillac they sell is the Escalade. Cadillacs are supposed to be large imposing vehicles that are visually impressive. Only the Escalade meets that standard. Everything else Cadillac sells are knock off BMWs. Cadillac shouldn't be in the business of selling compact 4 cylinder crossovers. Dime a dozen vehicles. You'd be better off buying a high trim version of any mainstream crossover than an XT4. Why does a CT4 start at the same price as a Camry XSE? Why do Buicks have nicer interiors than Cadillacs? Why to CHEVYS have nicer interiors than Cadillacs?
EBFlex “Insatiable demand” Pretty sad when even the Uber deranged EU doesn’t want EVs.
Jbltg Had a rental like this once, stock of course. NYC to Vermont. Very smooth and quiet, amazing fuel economy. Not the best for interior space though. Back seat and trunk barely usable.
