I mean I guess I wish they had gone faster? What's the problem here? They're trying to make and mass produce an electric semi truck.

problem is they keep acting like they've already done it

What are you talking about? General media vibes?

Good grief. More Volvos (and Scanias): https://www.youtube.com/watch?v=Sq4jpgrMk64 And more Volvos: https://www.youtube.com/watch?v=rWKHFiB4XG8 And more Volvos: https://www.youtube.com/watch?v=MrkbPwlz_YY And more Volvos: https://www.youtube.com/watch?v=0ocC5qdrAOU And more Volvos: https://www.youtube.com/watch?v=8Dgdk555G0g And more Volvos: https://www.youtube.com/watch?v=K3EA6Y5CT2E You really need to stop allowing…

bro you are sending me MARKETING VIDEOS and telling me not to be brainwashed by advertising. i simply tried to look up the number of trucks volvo and freightliner SAY they delivered

Dude, you plainly didn't watch the first video where the name of the company operating the truck is WRITTEN ON IT. Your lazy response to that one was: "The first one we don't know if it's a customer."

Try watching them start to finish.

In the meantime, Volvo will get on with building and delivering BEV trucks and buses. Try not to worry so much that these practical realities invalidate your faulty preconceptions.

Funny how politics distorts one’s view of reality. Does anyone remember the state of the electric car industry prior to Elon Musk? You don’t have to agree with every (or any) opinion of his to acknowledge this lol

> Does anyone remember the state of the electric car industry prior to Elon Musk? Yep. We had the Nissan Leaf and a couple other minor contenders. And then we got the Bolt just before the Model 3 was released, and the Bolt is still by far the better value. The Model S made EVs sexy for a time, and that's nice, but it's hard to say that it meaningfully accelerated the transition overall. EVs were in the pipeline alrea…

Well Tesla did prove that EVs can road trip reliably and did design the north American standard (which before was named with great hubris but now is actually accurate against all odds).

I love my OG RWD Model 3.

The US is too big for long-distance passenger rail. Where density is high enough, local rail mass transit exists.

Most of the US lives east of the Mississippi River, where population density is commensurate with Europe. No one seriously proposes HSR from SF to Boston, but HSR from, say, Chicago to NYC is within the bounds of viability. And it's frankly criminal that we don't have 4h travel times from Boston to DC. As I've said in the past, the only cities of the 50 largest in the US that are unquestionably out of HSR range are D…

If Amtrak was allowed to ditch its expensive long haul rail lines and focus on reinvesting in Acela we could have those 4h travel times and they would turn a profit at the same time.

That is certainly one way to spin incompetent product design.

Incompetent? Show me a battery-electric semi truck with greater range. When you're actually doing something barely possible, it's hard.

Are we talking range confirmed by third party or range claimed by a company who actively lies about the range of production vehicles and actively suppresses customer complaints that the range is grossly inaccurate [1]?

Honestly "Musk always gives timelines that are completely unrealistic" is a pretty tired criticism at this point. Is it true? Absolutely. Does it matter much? Not really. They're clearly making progress. Not sure what more you want in real terms. Not being able to stick to self-imposed deadlines isn't ideal, but its also not a crime.

It wasn't just the deadlines, he also declared many things as already achieved, including some patently impossible (such as 200kWh Roadster). Perhaps worded so SEC can't get his bum, I don't know. https://www.youtube.com/watch?v=FZeB7SwmkiQ

Why do you believe a 200kWh battery to be impossible?

Priuses are slippery little kammback hatches with hard tires and a drivetrain designed to minimize Cd and stop-start traffic fuel consumption. A semi is a brick that bullies the wind out of the way all day every day for two million miles before needing a rebuild. They're very different animals for very different use cases.

Its a long brick though, it shouldn't be considered a bluff body

Sure, the wake is thinner relative to the length, but that's not the relevant variable. The drag is still way higher for the same frontal area than for the same width body that's shaped like a prius. and thus power required is much higher.

A 1.5-ton battery on a sport roadster? You tell me.

You can cheer on something that actually works, like Freightliner or Volvo.

Freightliner has delivered like 20 trucks I think, same as Tesla. And Volvo has possibly not delivered any?

Electric vehicles just don't scale up. Its just the nature of batteries, and really only way to overcome it is to have electrified network - trams, rail.

The bottom line for using batteries is simple and unavoidable (with current infrastructure)

The longer the travel distance the more bateries you need. The heavier cargo the more batteries you need. And the longer it takes to charge them. Batteries dont decrease in weight like diesel as journey progresses.

It seems that the maximum we can take EV cargo is small local delivery trucks for inner cities.

And Tesla itself is providing evidence for it. They have a video of Semi journey, where its repetitively overtaken by normal truck (they drive slower to save battery), their commercial partner use case is crisps/chips ie. carrying 99% air with 1% potatoes (semi serious joke).

So I wouldnt trust any EV truck company. And any creative solutions to the 'battery scaling problem' by changing the infrastructure seems to be pointless as you instead could just build more rail - a far superior cargo solution.
