Tesla exaggerating EV range for over a decade::undefined

This is pretty much my reaction to every corporate deception that I read these days:

[–] Motavader@lemmy.world 26 points 2 years ago (4 children)

I've tested in my own model 3 and the range and kwh usage is actually pretty accurate as advertised assuming you accelerate slowly, drive the speed limit, and don't run the heat, and don't have a strong headwind. Many people, including myself, absolutely do not drive like that, so the range will be less.

[–] thejml@lemm.ee 21 points 2 years ago (1 children)

This is honestly true for the ICE estimates as well. It’s just that people have a lot more range anxiety when they can’t find a refueling spot every other street corner.

Not that I’m condoning it. And not that they’ve always gotten away with it. They need to be held accountable to come up with reasonable range expectations.

[–] BobKerman3999@feddit.it 5 points 2 years ago

But also ICE are so inefficient that a small percentage change doesn't affect them so much because you're wasting 80% of the energy anyway so you load up megawatts hour of power when you refuel. On BEVs losing 4kw of power for heating or other stuff means a lot because you waste only around 5% of the energy, so adding 1 or 2 or 3% of other losses will impact the small energy storage you have.

It seems like it's an issue with manufacturing consistency/quality. The report said some cars were getting literally half their advertised range on daily commutes. That's not an amount that could be accounted for by driving styles.

The original Reuters report linked below: https://www.reuters.com/investigates/special-report/tesla-batteries-range/

[–] Casmael@geddit.social 2 points 2 years ago

Wow that’s super embarrassing

[–] astropenguin5@lemmy.world 9 points 2 years ago

Yeah it's all about ideal conditions, and same for ICE as the other reply said. Even external temperature matters for EVs too, if it's too cold the battery won't perform as well.

Wait, so you can't use the air? You know, one of the major comfort features in a car? What a ripoff.

[–] gadget@lemmy.world 3 points 2 years ago (1 children)

Running the heat can be energy draining because you don't have a hot engine to draw air from. Using the heated seats is much more efficient but of course less comfortable in cold weather.

[–] luthis@lemmy.nz 1 points 2 years ago

Oh 'Run the heat' means using the heater! I was so confused. I thought this was referring to driving fast or running from the cops or something.

[–] Motavader@lemmy.world 3 points 2 years ago* (last edited 2 years ago) (1 children)

You can use the AC is fine and you get pretty close to the rated mileage, but the heated air is a bigger drain.

[–] xthexder@l.sw0.com 2 points 2 years ago

Newer models come with a heat pump now, so running the heat should be just as efficient as running the AC.

and autopilot safety

[–] SulaymanF@lemmy.world 13 points 2 years ago* (last edited 2 years ago)

Isn’t this something for the FTC to prosecute? And then after that, class-action lawsuits?

When Apple got caught extending battery life on old iPhones without user knowledge, there were lawsuits announced by the end of the day. What about Tesla?

[–] dystop@lemmy.world 11 points 2 years ago

lol whats new

[–] TIEPilot@lemmy.world 11 points 2 years ago

I am Jack's complete lack of surprise.

[–] onionbaggage@lemmy.world 7 points 2 years ago (1 children)

Exaggerating?

Why don't we try lying, bait and switch. Perhaps criminal investigation for consumer fraud?

[–] jkure2@lemmy.world 1 points 2 years ago

Tell me the world isn't a better place if elon is sent to work in a lithium mine for the next decade

[–] Disgusted_Tadpole@lemmy.ml 6 points 2 years ago

[BRAND] exaggerating any kind of EV range.

[–] Chadus_Maximus@lemm.ee 5 points 2 years ago* (last edited 2 years ago)

So vindicated about all the arguments I've had with friends about Tesla's range not being as long as what we were led to believe.

I mean, I don't have those friends anymore, but still!

Color me absolutely not shocked. Corporations are always going to lie. I don't trust a word they say.

[–] AlecSadler@lemmy.world 0 points 2 years ago* (last edited 2 years ago)

I'm actually within about 5% +- on my Model S Plaid depending on the time of year and that's hardly driving conservatively (maybe luck?). Oddly enough, my Model S has been more efficient than my Model 3 LR was, which I know makes no sense. But pretty much across the board for all the same drives, I use less kWh, it boggles my mind.

This is based on data from Tessie.

All that said, I realize the article says other manufacturers have more accurate fuel economies. I'm sorry, but no, my friend's leaf is absolutely wrong by an extremely large margin, especially in winter, and has been since day one. It's not even close.
