Do you seriously believe this garbage? Spouting off a bunch of theoretical and irrelevant (as it pertains to trucks) physics doesn’t make you sound smart.
Yes, I do believe it. I've learned that physics tends to be real, not garbage. I've been part of a lot of things, including EVs, that pushed the laws of physics, they do apply, whether we like them or not.
You may not understand them from 1st principles, but you probably do from experience.
This:
A bare bones cummins diesel semi frame is ~800-1k lbs, a that is a truck that has a GVWR of 35k lbs.
Is consistent with the physics: Diesel has great Specific energy. One may not be able to just swap out that Diesel power plant with an electric one that weighs 14x as much and get the same performance.
Spouting nonsense about things that don't exist:
For EVs the Silverado EV is rated to 450 miles with a body on frame.
For aerodynamics. the CT is less aerodynamic then the Rivian. And Tesla is not an innovator in aerodynamics, 2023 Tesla Model s has about the same aerodynamic drag as a 1951 Saab 92.
As for the movable 600+lb battery…. Tesla has already released that it is a permanent installation that will have to be done at a service center. I don’t know how many 600 lb bricks you have moved in and out of a truck bed in real life, yes it is possible but I’m betting much more complex (and expensive) then it is worth.
are completely unsupported statements (or at least I haven't seen anything that convinces me yet). Until there are actual products out there (including the CT) for real, independent testing, all we have are the natural laws and marketing hype. Addressing the 1st principles is what enabled us to invest in the Roadster initially when all of the business folks said it wouldn't work. I'll continue to use physics as my guide until I see how someone works through the real issues.
. . . and there really are hard challenges as you point out:
and another consideration, if the range extender is for towing. Think of this, range extender+spare tire+WD hitch will put you at at least 1k lbs. A 25-28’ bumper pull camper will be 8-10k loaded and will give you 1k-1500 lbs of hitch weight. Now you are approaching or exceeding The CT GVWR without accounting for passengers.
I just don't see this being solved by traditional methods. I'll be happy for the 450 mile Silverado to prove me wrong. The unique design of the CT was different at least in a way that addressed these physics challenges (heavy battery weight). The question is whether it will prove to actually enable an EV truck? or are we stuck with ICE for full truck capability?
