First generation? According to Wikipedia and the few websites I could find, in American models, the rex had a different control setup that was simpler then here in Germany.

2018

And I was driving the 2013. So I rest my case.

For people thinking that pure ev + backup generator is more reliable than PHEV, i recommend this video : Nobody understands the point of hybrid cars from Technology Connections It explains why PHEV is actually a very clever idea and now it simplifies things not complicates them. https://www.youtube.com/watch?v=KnUFH5GX_fI

Indeed this. A range extender engine will never be as efficient as hybrid

Less maintenance the traditional engine. well assuming you plug it in of course but if you're plugging it in you're only using the edge for longer trips and so you're going to save a lot of money while still having range to make longer trips. Of course there is some worry about the gas going stale if you never run that engine. On the other hand gas engines get more efficient the higher the load and so a generator opt…

> Less maintenance the traditional engine. I can tell you from experience it really isn't much less. Stale gas, dry-rotted hoses, dry/cracked seals, failed starter, fried ECU, fried coolant pump. Also account for the entire other subsystem, the IG. A complex subsystem with an entirely different set of warts: shredded splines, cracked coolant lines, corroded LV/MV connectors, leaky coolant lines, fused contactor. Perh…

Mechanics often have a skewed perspective, though, and so I don't necessarily trust your experience because you see that bad cases.

The reality is a modern engine is very reliable in general and yes, seals will go out but that's more a matter of time and I expect to see that in any car in 10 years. Although I have no information on the particular engine in the case here and so maybe this is a particularly bad engine but that's not an indictment against the concept itself. If a modern gas engine car can't go 300,000 miles, it's because the body has failed, not because the engine failed. Sure, you'll have some maintenance, but it is well known and fairly cheap considering all the work the car is doing.

Won't gas just varnish if you don't ever have an emergency where you need this? This seems ill conceived.

Again, the Volt already blazed this trail since 2011. The engine automatically comes on at least once every 6 weeks, and overall ensures that a single tank of gas doesn’t stay for more than ~6 months IIRC. I’ve never heard of any fuel-related engine problems on Volts.

ITT: a disappointing number of low-effort drive-by comments responding to the headline alone.

It's 1) the WSJ and 2) a really dubious headline

I don't find it surprising or disappointing that ppl aren't bothering to go read the article because of the two factors in conjunction above

I'm not clear what you were doing with an engine then. Unless you were part of the design team finding and fixing bugs and making the engines reliable for the rest of us.

I enjoy that guy, but I've found he is wrong about what he talks about in several situations. This is probably one of them, but we'll see once the EREVs are tested. His argument here is basically, "The Volt wasn't fuel efficient so EREVs can't be". Ignoring all the has been learned about EVs since then. Plus he ignores that PHEVs and Hybrids are more complex than an EREV because they need complex transmissions and other subsystems because they need to be both an EV and an ICE vehicle.

I have an EV and a hybrid, and the EV is so much better than the hybrid - I will happily swap the hybrid for an EREV when the time comes.
