Tesla warns that a federal probe into whether it exaggerated the range of its cars may lead to a ‘material adverse impact on our business’::Earlier this year, Reuters reported that Tesla had created a special “diversions team” to avoid dealing with complaints from customers about their vehicle ranges.
I believe you are correct. Maybe they are latching onto the range issue because it affects every Tesla owner, past and present. Also very easy to prove.
Tesla doesn’t lie about the EPA range though. It’s reproducible even if those aren’t “real world” driving. If we want real world driving numbers that’s up to the EPA to change the methodology.
Range displayed is always just an estimate anyway, with so many variables. If they’ve fudged what gets displayed somehow that is clearly bad and we need to know, but the EPA range (edit: on a brand new vehicle) is legit. I dont see how them being wrong on this would be so dire.
I think the AP investigations are a much bigger problem and also impact nearly all Teslas. What if Tesla has to disable AP or can’t let people beta test FSD which could grind their data collection to a halt? That seems immensely more material adverse to me
Edit: clarity, but also to add, what if they can’t even sell FSD period, and need to refund all sales of it, PLUS damages to owners?
Edit: Just some other thoughts on this only semi related to the actual accusation, but batteries degrade, and Tesla does show a degraded range on their estimates, but maybe we need better laws like EPA ranges must be met for X years. It would force manufactures to declare a range lower than the car is capable of (no one drives below 0%) as they would need a reserve. It would also help offset any variations from the actual EPA test. I believe Tesla warranties the battery for up to 30% degradation over 8 years or X km, so that would get lowered somewhat due to the reserve. I think something like this would be better for consumers overall?
Sort of yes and sort of no.
Tesla displays the vehicles “range” as the EPA range minus any battery degradation. The number doesn’t fluctuate otherwise.
However, if you plus a destination into the trip computer, it actually computes the estimated efficiency and you can estimate the range from it.
Every other EV instead has a “guess-o-meter” which estimates the remaining range of your car based on current driving habits and derived efficiency by looking at the recent X number of miles driven… this gives you a good range estimate which automatically factors in recent weather, terrain and driving habits. It also takes into consideration your current battery health.
Only the trip computer is particularly accurate. Tesla has theirs, while everyone can download the app abetterrouteplanner.
Personally, I think it’s a relatively non-issue. Rather, there is a methodological difference between estimating the range. Gas cars, otoh existed for 100 years without having a range estimator.
Exactly. I don’t think Tesla showing the EPA range after degradation and state of charge is anything to be concerned about. If there’s a problem with doing that, then the problem lies with the EPA/regulations.
I’m not sure what this whole different numbers at 100% vs at 50% is unless they do turn on a guess-o-meter if you reach 50%, or maybe Tesla is fudging the battery degradation to show a higher 100% and then adjusts it as you start driving, but either way, I don’t think it’s the big deal this articles title is trying to make it out to be. The number at 100% will be accurate to the EPA test cycle on a new vehicle, and I think that’s the critical piece here. They aren’t lying about that. The numbers have been audited.
I do still think we need better more accurate EPA tests.
Edit: Actually if they are lying about the level of degradation to fudge the numbers, that could impact warranty claims and the 30% threshold, so that would be bad.
Yeah, it’s top line number is basically the estimated range at 250WH/mi given the cars estimate of battery capacity.
It’s not hard to get or even beat 250WH/mi in good weather on relatively flat highway if you are moderately careful about it. It’s definitely an upper limit though, which I think is appropriate. I don’t care how much range the car has with a lead foot. Top Gear showed that an M3 can get better mileage than a Prius when both are doing performance laps, so that’s kind of just a dumb way to measure range/efficiency.
Yeah, you definitely need to be careful and the conditions need to be close to ideal, but I routinely get the rated range in a model 3 without any trouble. It’s like any other car though - elevation change, weather and driving habits play big roles in efficiency. The car also has nearly 500hp on the top end so it’s very easy to kill your trip efficiency with even just one or two bursts of high acceleration.
