EVs suddenly don’t get good fuel economy?

[–] [email protected] 27 points 1 year ago (1 children)

I mean, with EVs, you compare the economy to other EVs.

The cybertruck would use, according to at least one estimate, about 350 Wh/km, which puts it as the least efficient EV (including an old source). Compares to about an F-150 Lightning.

The Hummer has 419 Wh/km, or worse, so even with that estimate it wouldn't be the worst.

That's a lot. Looked up numbers for high-speed rail: for passangers minimum is 29Wh/km/sest in Japan and maximum is 41Wh/km/seat for Eurostar, for freight it's between 315Wh/km/t and 525Wh/km/t. Again, this is for high-speed rail at least 300km/h. For slow speed train(for example 90km/h) this will go much, much lower. Probably something between 30 and 100Wh/km/t.

Darn that's less than half of what I get

If it's a new car, then it's less efficient than your old car. This is still true (or possibly even more true) for electric cars.
