Tesla committed fraud by “grossly” exaggerating EV range, class action says

Anecdata, but a few weeks ago I drove from LA to SF in my 2018 Model 3 (long range, single motor). It has a 75 kWh battery pack, my drive was 417 miles, and I drove 70 mph for probably 90-95% of the trip. I used a total of 95 kWh, which equates to ~329 miles on a full charge (100-0%). My efficiency was 226 Wh/mi. There are absolutely other times when I'll get substantially less range, but it's understandably when I'm…

My iPhone can send me alerts that I’m going to be late to work based on its tracking of my daily commute and you’re telling me that a machine that is constantly connected to a GPS network, sending data back to home base, and (almost?) capable of driving itself has “no way” of “magically knowing where you’re driving” unless you tell it? If only they could use some of that data and processing power to back out someone’…

data from 3300 drivers from the very article we are discussing disagrees with your single anecdote.

It's not an anecdote, it's physics. EPA created a repeatable test where the car runs at a certain speeds, most likely without wind resistance. If you drive faster, the car will use more energy per mile therefore will have lower range than the EPA estimate. If you drive slower, they car will use less energy per mile therefore will have higher range than the EPA estimate. If there's head or side wind, the car will use…

Shouldn't the car know the current temperature (or at least the battery temperature), whether or not the AC is on, etc? Other EVs take those into account regardless of whether or not something is plugged into navigation.

If you want the accurate range prediction, navigate to somewhere, the prediction is always spot on to the percent. Or view the energy screen, also extremely accurate. Just don't depend on the EPA range, go with what the car calculates when you navigate and you will never have an issue.

So the car only lies to you about its capabilities in some contexts? That's reassuring.

This take is a bit weird to me. It’s like saying because other companies aren’t lying that Tesla should be excused from lying. It sounds like Tesla has been displaying this number in car regardless of the accuracy; and in my opinion leaned into lying. From the article: > The complaint cited testing that found three Tesla models fell short of their advertised ranges by an average of 26 percent. In addition to alleging…

Right, and the one that is accurate is what you get when you put in a destination. The car can't tell you how far you can go if it doesn't know where you are going, because of all these factors (altitude gain, direction of wind, speed limits on the various roads involved, etc) which have a very significant effect on the range. The idea of a single value for "range" is fundamentally flawed. Is it Tesla's fault that pe…
