“The point being made here, at least by Polestar, is that its vehicle is potentially more energy-efficient”

I own a Model 3 Performance like the one tested here.

The Model 3's battery is just slightly smaller than the Polestar's, and a fair bit smaller than the other 2, so it *is* a lot more efficient. 

I just looked up all the pack sizes and the ranking for distance per KWh worth of battery puts Tesla in 1st, Polestar in 2, Jag at 3 and Audi 4.

I don’t think the test is about efficiency either. It’s like, how close do you come to the EPA range vs their arbitrary test’s range.

This study is not about efficiency. We can use the data in conjunction with battery size to make some new assumptions though.

Polestar: “Tesla has the lowest score!”

I’m not sure what you’re even measuring here. Efficiency isn’t a measure of EPA rated range in a different test environment vs actual range on a test track.

Also, let’s consider battery size for the contenders:

That’s not actuate for the Model 3. It was a Performance model with 20" wheels. The EPA estimate is like 299, not 310. The 310 is with the 18" wheels. So, the real difference is 78.2%. They also do not state that they charged to 100% prior to starting the test. I don’t know whether regenerative breaking helps on thehig…

The same team determined the HD3500 is more “efficient” than the Prius since it has a 40 gallon tank.

What should be measured is energy input per distance traveled. Measuring consumption should start with an empty battery to include charging losses, which can reach up to 25% during fast charging on some cars.

Yeah, this is idiotic. Show us the miles per kWh, otherwise, don’t use the word “efficiency”.

That’s not a test of efficiency, it’s a test of accuracy relative to EPA testing regime.

Wouldn’t a better measure of efficiency be distance traveled vs battery size?

Unfortunately, max possible charge rate is also related to the size of the battery.  The smaller battery will recharge in a shorter time, but if you just need a 20kWh top-up to get home, a bigger battery will take a faster charge rate (within the limits of the charger).

200,000 pre-order deposits in less than 24hrs? Yeah, you’re probably right.

Reading through this whole thing was painful, it’s very clear why they went with the thicker gauge stainless steel-it’s a load bearing part of the unibody that gives the truck the strength needed for the high bed payload and the high tow rating. That thicker steel is critical to the strength of the structure since…

I think you missed the part about why the metal is so thick - the truck doesn’t sit on a frame, the sides ARE the frame. That’s actually pretty brilliant if it works, since they aren’t wrong about the frame being one of the heaviest parts of any given vehicle, and serving no real purpose except to hold everything else…

I mean, it’s really goofy looking, but being that I’m a Suburban Dad, I’m actually interested in it.
