re: GM delays start of EV production at Michigan plant due to lack of demand

There will never be a demand for EV trucks.
My mother impressed on me at a young age the words "never" and "always" are the two most dangerous words in the English language. This is especially true when used with an open-ended period of time in the future.
The thing about trucks whether it is light, medium, or heavy-duty is the power delivery characteristics of an electric motor are far superior to a gasoline/diesel motor for the application. They also facilitate a far simpler and potentially more robust power train. The primary issues are energy storage density and recharge times with a secondary issue being initial cost. When (I don't think if is in the discussion) those issues are "solved" then electric motor powered trucks will become ubiquitous.
When towing or hauling heavy loads massive peak torque from 0 rpm without using a torque converter/transmission with the necessary slippage along with multiple gears is just a huge advantage. This is something the railroad industry learned 70 years ago.

They don’t even have enough ev certified techs either

All I can say is that the 3L baby duramax is amazing

I haven’t heard they’re idling all of them. I think hammtramick is still rolling to fill orders.

I think they will. Of all the EVs, Trucks to me are the most intriguing.

I don’t think auto makers predicted a high demand.
The government is pushing it and few actually want it.

I love the baby diesels even after washing the funk of the old rams spitting main seals out on the highway. But they still have the same fleet issue that makes the EV use case work.

Not having to stop and fuel up and not idling all day are big efficiency gains and save companies a lot of money.
I'm sure not filling up on-site but instead charging on-site saves millions.Posted on 10/18/23 at 7:20 pm to Jcorye1

They charge overnight and prevent the 45 minute gas station stop. Workers show up everyday with a full charge and go to work. The fuel saving from idling all day can be significant. The last fleet I managed was spending 100k a week in excessive idling fuel.

Except consumers are less concerned with off-idle torque than any number of other factors. In fact many current truck buyers absolutely clueless about such a metric let alone the general public. Current trucks are limited by their frames, not powertrain.

120 years or so.
Straight electric locomotives were in service long before diesel-electrics.
*For those that don't know, a diesel locomotive is actually similar to a power plant on wheels with (electric) traction motors on each axle. The prime mover (diesel engine) turns a main generator (actually an alternator for the past 50 years but the name remains) to generate electricity.

GM and Ford never learn. So wish they would have gone out of business.

They chose very different paths on this. Ford only targeted the consumer market for the lightning. GM went after the fleets. They haven’t idled all production in the Silverado EV but have idled one plant because they aren’t seeing the demand they expected. I imagine that’s from the consumer side since the fleet orders have been strong.

Agreed.

I disagree, no need to continue this nonsense and it can be changed.

I find this difficult to believe. Care to share some backup besides speculation?
"They're selling those EV's like hotcakes!"

And the beauty of this system is almost unlimited power with access to diesel fuel.
Also the ability to continuously vary the power/torque to the final drive electric motors by adjusting the motors power factor while keeping the diesel fully loaded at a stable, efficient rpm.

That’s just picking winners and losers.

Fleets have put in a shite load of orders for the Silverado EV w/t. That’s not speculation. It’s real.

No, the government subsidizing EV tech and penalizing ICE vehicles is exactly what is happening, and that is picking winners and losers...
You're correct but misguided.

Only if you ignore the massive supply chain subsidization for o&g.
Look at the DOE funding of the ecoboost development.
