Of course its newsworthy if the company making the most electric cars in the world has setup a factory to produce semis and produced at least one after years of testing with actual customers that say they are very happy at seemingly very competitive pricing. To say its NOT newsworthy betrays a bias against Tesla which I would assume has nothing to do with actual facts.

I agree that this is mildly interesting. But wanted to say BYD produces the most electric cars.

It’s been three years in a row: https://finance.yahoo.com/markets/stocks/articles/tesla-mode...

"for the last three years" was another strong qualification the grandparent post did not make.

no you're right sorry it's not up to your standards of selling as many cumulative units as cars that have been sold longer than most readers of this website have been alive

~10 min to fill diesel semi. So electric can only service 1/3 of semi, when truck stop is at full capacity .

But you can go 1500 miles on a full tank, so with electricity you have to account for three times as many vehicles as well (given the stated range is correct)

300 miles between charges if you are limited to a 30 minute charge, but semis probably refill much more often than every 1500 miles, particularly since they are required to stop every so often anyways.

My first job was pumping gas at regular neighbour gas station and one day a semi rolled in because he was low on gas. He insisted that we use both diesel pumps on the pump so that it would take faster and it still took forever. I can't remember if he filled both side of his truck but if he did that would have required him to go around the island to get the other side tank. I've only been to a cardlock station a few t…

stats vary. seems ~250 is common (2x 125 gals) and long haul ranges up to 2,000 miles. Though another way to think of filling up is miles per minute. At 10Gal/Min and 7MPG that's pumping 70 miles a minute into the tank. an 80% charge in 30 minutes on a 500 mile range battery is ~13 Miles a minute so roughly 5x slower

60% charge in 30 minutes (20-80%) so 10 miles/minute and 7x slower.

A 30 minute charge means each charger can service a maximum of 48 tractors per day, and realistically probably less than that. I wonder how many trucks fill at a typical diesel filling station per day.

Have you seen the demo's of "truck pack" batteries being removed from prime mover, transferred to charge station, replaced with already charged truck pack, all done with a mini fork lift? It's a 15 minute roll in / roll out kind of turn around. The game's not over and the big transport operators (eg: Rio Tinto mine fleets moving a billion tonne per annum, etc) are still doing the R&D pipeline and trialling pilots.

This is a non-sequitur for Tesla's Semi truck which does not support this. It's also possible to build trucks with larger batteries and faster chargers.

I think we should do is have a second trailer that basically functions as the primary battery pack. The tractor's pack is back up or range extension So when a semi pulls into a truck stop, you swap that caboose cab with a fully charged one.

so you have massive batteries just sitting on chargers waiting for the next truck to come by? seems expensive

How's that different than a battery swap that every other person suggests but doesn't seem to really mechanically make sense.

Out of those, only the Camry and the Corolla even make the top 10: https://www.statista.com/statistics/239229/most-sold-car-mod...

And as the other commenter has already pointed out, you didn't say "for year 2025" only. That said, I'm surprised that the RAV4 is that popular, in the year 2025.

Why do you think the ranking changes that much from year to year? Model Y had the top spot 3 years in a row since 2020.

Doesn't really matter, load is a really small factor in EV range.

> load is a really small factor in EV range. That is just plain wrong. There is a reason why all EV companies, including Tesla obsess over energy density, and it’s because load is one of the biggest factors that affects range. Forget EVs, load also affects range for traditional Semis. Do you seriously think an empty semi and one with a shipping container on the tow, would both have the same range?

For long routes over level terrain it has almost no effect at all.

Sure to a commuter in stop and go traffic or city driving it might matter a bit but regen takes away the first order of magnitude.

Even climbing a hill is a bit of the same effect. To first order, you recover it on the back side of the hill coming down.

Okay, sure, for one year. But "for year 2025" was not a qualification the grandparent poster made.

> for year 2025" was not a qualification the grandparent poster made.

I interpreted the comment to mean that Tesla model Y is currently the most widely sold car in the world, not historically. model y is less than 10 years old.

i think it shows that tesla is actually able to ship cars at a high volume, which was the point of the thread.

Energy density is energy per unit of volume . Every company obsesses over that because volume is the limiting factor for getting energy in a vehicle.

Well arguing load isn’t a factor and the real limitation is the volume is still wrong. EVs aren’t infinite in size and real world constraints exist. At the end of the day, your semi cannot be 90% battery and ferry only a pallet of chips. Total energy spent on moving an object by a distance is still proportional to the mass of the object. So if you’re absolutely spending more energy hauling 10000lbs vs 100lbs. The onl…

> Total energy spent on moving an object by a distance is still proportional to the mass of the object.

It is not. The energy spent to change momentum is proportional to mass. For mass to affect momentum you need a second order effect linking it to increased system losses e.g. a heavier plane needs more lift, which requires higher speeds, higher angle of attack, larger lifting surfaces, …, all of which increase drag, which is the primary way planes lose energy.

> Rivian an electric car company admits that towing will reduce your range. There’s a reason for that.

The reason is the increased resistances (air and rolling) from the trailer: https://youtu.be/UmKf8smvGsA
