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.

Fuel cells are pretty cool. My friend has the Toyota one. They're pretty good in CA but have a ways to go before practicality. I believe you can only lease them ATM because they cost about 400k. They're definitely a viable tech though!

I'll also say that part of the Tesla ecosystem is the self-driving and performance, not just earth friendly.

Also you compared an SUV to a Sedan which is supposed to be flat as a pancake. lol. A better comparison would be the model Y.

Earlier quoted context omitted.

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 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).

Other EVs have been using heat pumps for years, like the i3 and LEAF. I don’t know why they didn’t go with it for the 3, or retrofit it to the S and X.

and how many standards-compliant hydrogen refueling stations exist right now in the 48 states, compared to places you can charge an EV?

Another bonus of having an EV is charging in your own home. You end up with a full tank every night.

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...

Sounds like they have the mix of estimated speeds wrong. EVs perform significantly better at low speeds, because there’s no extra efficiency in the EV power train at higher RPMs, and air resistance scales in a nonlinear fashion.

For those wondering this is a Hydrogen fuel cell car, only available for sale in CA because that’s the only place you can fill it. It appears they sold about 270 units in the US last year.

"a new custom tire" sounds expensive to replace when you drive over a nail

Fair point, but this is Tesla we are talking about. They will find a way to make price competitive (possibly after failing a few times first).

The Tires are one of, if not, the least understood things on a car, so I'll believe it when I see it.

Not one like this. The Model 3 "superbottle" was the best in the industry for the problem they were trying to solve with it. The Model Y "octovalve" heat pump is the successor and does things even better (and it is patented FYI).

There's always a lot of folks claiming to get equal to or better than the rated range on the highway, but I will add my anecdata in for however much it's worth. I have a Model 3 Performance and it does not get anywhere near rated range, regardless of weather. I more realistically get 200 miles of range, not 300.
