Yep, we've been discussing it since November of last year: https://www.jlwranglerforums.com/fo...cluding-next-gen-j70-wrangler-ev-repb.120833/. REPB might be compelling.

Yep- an REPB Wagoneer announcement with others coming verification. Less complicated, more range, no downside obvious (but possible). When combined with the new SS battery tech in a few years I might even consider one. Well, an REPB as a GC replacement. Guzzling fun Wrangler is a keeper for this old gear head.

REPB = Range Electric Paradigm Breaker. REPB will use an ICE as a generator instead of powering the wheels, allowing the battery to be recharged on the go

So has nobody actually made an EV that uses ICE solely for recharging before? Top Gear UK made their Hammerhead Eagle i-Thrust diesel-electric hybrid back in 2009. Imo, it's the only type of EV that actually makes sense in a country with remote and expansive wilderness like the US.

Bmw i3, it's been done

Chevy Volt

Almost. We have one. It has a clutch between the ICE and transmission that engages if the electric module pulls too much from the battery, faster than the ICE can charge it, the ICE drives the transmission directly.

With the battery depleted, it gets about 40mpg.

Yep- hadn’t seen that one, but a small constant speed diesel would be much more efficient than a larger gas engine.
We had 100’s of small diesel generators on refrigerated trailers , with 440V plug in when stationary and available (our satellite yards) again, what took them so long ?

uh- don’t grab the 440V plug that some idgit threw on the ground in the rain, without checking if it’s off or you become idgit #2. Fortunately, the arc got me and knocked me on my ass before I latched onto it.

I don't know....
Take all the complexity of an ICE vehicle, and combine it with all the complexity of an EV, then have a company like Stellantis build it?

Thanks, but I'll stick with my good ol' tried & true gas engine.

Coming from someone accused of Blind Hatred of EV’s, this is the only one I presently find acceptable. The complexity of an EV, but with a simple added generator….. production models since 1914, without a battery.

Gas prices may relegate V8’s to part time fun use, alternative for one of them for a DD being watched.

Think of all the compromises that are made in an ICE to provide a smooth, powerful torque curve from a bit over idle all the way to redline. Those compromises go away when that ICE is designed to operate at one specific RPM (not RPM range, a specific RPM) that it is most efficient at. Have you seen how complex variable valve timing can get? Crap like that all goes away when compromises related to engine speeds are no longer in the mix.

Depending on how many motors are involved, there are a crapload of existing parts that potentially go away.

No need for a transmission. Or a transfer case. Or drive shafts. Or axles. Or differentials. Or lockers.

In that scenario, however, we wouldn't have a solid front axle, which would suck from an articulation standpoint.

Powerful ? ! (Source 2020 thread) Compilation for average torque

All very good points, and quite interesting... I'll give you that.
I'm just a not confident in this company's ability to pull it off initially.... maybe after a few tries?
I kinda think they need to work on basics first like metallurgy for example (think door hinges).... I'm not really trying to sound snarky, but come on Stellantis!

Exactly. It just needs to be sufficiently powerful at one relatively efficient RPM. The rest of the torque curve is irrelevant.

With the system going in other vehicles too they could maximize efficiency— profile a cam for a constant ~ 16-1800 rpm , TB and intake for low rpm velocity, high rpm flow not needed. Heads too, if if the redesign cost is worth it.
