Did everyone miss the news that Mazda is bringing back the rotary engine? Or maybe you don't like it as a range extender for a hybrid?

Can it deliver good enough fuel economy to make sense?
My 16 year old, 190,000 mile reliable-as-the-day-is-long, abused like a rented mule Nissan was also built in Tennessee.I would like to point out that the Arteon is built in Wolfsburg and the NMS Passat is made by rednecks in Tennessee.

I thought the SRT Hemis (6.1/6.4/Hellcat) didn't have the variable displacement stuff?
Well, as a range extender genset it'll run exclusively at it's exact most efficient RPM under it's exact most efficient load factor, since the engineers get to pick that.Can it deliver good enough fuel economy to make sense?
what about, say, a boxer twin?Well, as a range extender genset it'll run exclusively at it's exact most efficient RPM under it's exact most efficient load factor, since the engineers get to pick that.
This also means it's not going to have that spinning dorito sound, which is a shame.
But it is small and light, which is a thing you don't get out of piston engines.
More moving parts and not a Mazda thing. BMW, on the other hand...what about, say, a boxer twin?
Companies making range-extender vehicles seem to use whatever's coming off their assembly lines in large numbers. That Scania bus you mention...for those bigger vehicles you're basically using the electric drive as a transmission, right? Like a diesel-electric locomotive?I wasn't talking about Mazda specifically, and I did actually have BMW in mind. It's also just me trusting piston engines more. I have nfi if it's going to be any better.
I seem to recall reading somewhere that Scania had a couple of prototype hybrid buses in the late 80's or thereabouts. They had an electric drivetrain and a range extender genset using a Saab 9000 engine. They didn't last very long since they spent most of their time at full load with the turbo glowing white.
Yeah, that's how you'd do that. That particular instance seems like just catastrophically bad engine choice - the engine needs to produce enough power in its most fuel efficient spot on the power band - and lower RPMs are better if you've got more than one choice - not at full blast.Companies making range-extender vehicles seem to use whatever's coming off their assembly lines in large numbers.

Right now the car companies seem to be cheaping out on range extender gensets, but hopefully of this wankel thing works out it'll prove there's reason to look at more unconventional engines that take up less space and are purpose built for the job.
Maybe we'll get a small engine renaissance out of it.
Sometimes I have to wonder about dealers.

Yeah, but if they're selling it surely somebody is buying.Fixed that for you
