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?

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.

Energy specificity (energy by unit of weight) is only relevant to planes, no EV company gives much of a fuck about it. Would they like it if batteries were lighter? Absolutely. Would they take a heavier battery if it was denser? In a heartbeat.

> Forget EVs, load also affects range for traditional Semis.

There are major differences between a traditional prime mover and an electric one: electric motors don’t have the divergent torque/power curve of ICE, or the choked low end, and moving a load is kinetic energy which EVs can largely convert back into electricity instead of losing it entirely. So the inefficiencies related to getting the load moving largely go away.

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

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

The Model Y is neck-and-neck with the Toyota RAV4 as the most widely sold car model in the world.

I am not convinced this is true. But perhaps you are using different criteria than this source. For example the Toyota Corolla has sold 50 million, the Model Y, slightly over 2 million. https://en.wikipedia.org/wiki/List_of_best-selling_automobil...

The Corolla has been on sale since 1966. The Model Y has only been on sale since 2020. Annually, the Model Y outsells the Corolla. https://www.accio.com/business/corolla-best-selling-car-in-t...

> Toyota RAV4, the most widely sold car model in the world. Nope. Widely sold cars are the likes of e.g Toyota Corolla, VW Golf, Honda Civic, Ford Fiesta, Toyota Camry and Hilux. The other reply gives the link. The RAV4 isn't ones of these.

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

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 only point where the cargo is relatively immaterial to the range is when it is a very small percentage of the actual weight of the vehicle. But that doesn’t mean the vehicle is efficient. It’s just that now you’re spending more energy hauling the battery itself than the cargo. Energy density matters in semis because companies want to spend less money hauling the battery itself than the cargo to make it viable.

Rivian an electric car company admits that towing will reduce your range. There’s a reason for that. https://rivian.com/support/article/how-does-towing-affect-ra...

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.

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

I don't believe you. Can we have some numbers?

So basically, way less than the 206, the beetle and probably a lot of US/Asian car i've never heard about.

The Tesla semi is the only truck with a 500 mile range. So it does have an advantage over other electric trucks for long-haul trucking.

My model 3 also “has” 350+ mile range. Barely goes 270 in the real world with conservative driving. Trucking needs a lot more.

Try doing 68 instead of 75.

Things being towed by a Rivan are going to be less standardized than what a semi is going to tow.
