I'll wait for Consumer Reports or the EPA before believing any of Tesla's range claims. E: As in from the EPA itself and validated by Consumer Report's field-testing, not Tesla claiming EPA certification and verified through easily cheat-able testing.

Respectfully speaking, if you read to the second sentence, you'd learn the range is an EPA rating.

Teslas are known for achieving only 75-85% of EPA in the real world.

This is based on my own data, owning multiple Teslas over four years.

The issue is that short drives suffer HVAC losses and long drives are at highway speeds, which is significantly above the speed the EPA uses for their dyno. tests. Further, Tesla actually runs the tests themselves and uses their own calculations to simulate wind resistance.

The Hyundai Nexo EV is already at 380 miles, and it’s a real SUV, not a flat-as-a-pancake Model S. It refuels in five minutes, to boot, but is only practical in California. If they increased tank volume by 5% it’d be at 400 miles EPA.

You should mention that it’s a hydrogen fuel cell vehicle if you’re going to compare apples to oranges.

To save people googling, the Hyundai Nexo EV is a hydrogen fuel-cell car, not battery electric.

That looks pretty sweet honestly. I know it's not a far out take, but my feeling with the established car makers that are doing fuel cells (e.g. Toyota, and in that model Hyundai), want to learn how to build cars that run on electricity, and put too many eggs into where the electricity comes from.

From the outside it looks frustrating that they are not going full tilt while Tesla does Tesla things, but I hope I see where they're coming from.

I've been following a multi-month discussion over in the r/electricvehicles subreddit about EPA range. There's a growing consensus that something is very wrong with it.

Here are a couple of the articles that got some discussion in that sub:

https://insideevs.com/news/407807/eletric-car-real-world-ran...

https://www.caranddriver.com/reviews/a30874032/porsche-tayca...

As someone who has owned both a Tesla Model X and one of the other EVs on the list from the first article, I can also provide my own anecdata that at freeway speeds Tesla routinely underperforms their EPA range rating, and by quite a large margin. Meanwhile at freeway speeds my non-Tesla EV routinely exceeds its EPA rating.

That's not to say that Tesla hasn't done an amazing job at maximizing efficiency in their cars. They have. Just maybe not to the degree that the EPA test would suggest.

I think they mean they’re waiting for the EPA to test it themselves. Tesla conducts and self-certifies their own tests, and to my knowledge the EPA has never tested one in their own lab.

The HVAC losses are much less in the Model Y due to the heat pump / octovalve, something I wish they'd update the new from the factory Model 3s with. Sandy Munroe did a full Model Y teardown and has a whole segment on how this simple invention is brilliant as it increases real-world range.

Edit: mentioned the octovalve, which has no equivalent in any existing EV (i3, taycan, and leaf included).
