Tesla and Musk especially spreading lies? I'm shocked...

Can people stop dickriding them, especially Musk.

They literally had a team of people dedicated to covering this up, therefore admitting the range was incorrect, and people still are questioning if it's true? Wow dude

My Model X has been waiting for parts after an accident since NOVEMBER.

I genuinely love the car, but nobody should be going anywhere near Tesla until they get their supply chain in order. Nobody gives a shit if the mileage display is off by a few miles when they can't drive the fucking car for 9 months.

I’m not sure what speed they’re driving at to get 150 miles of range… It’s a simple fact that most EV owners should know that efficiency is inversely squared proportional to speed. I could get 300 miles on a full charge after 1 year/37,000 miles in my Model 3, in 50F weather by just going slower (55mph) and running the seat heaters instead of the heat. The battery degradation is the largest after the first year too, so this is great.

Although I do just keep the display to percentage now. I still use the 1% = 3 miles calculation, even though it’s slowly getting worse than that.

Sure, but the article indicates that tesla was deliberately inflating predicted range in their in-car displays. In other words, they were/are engaged in fraud.

I didn't see it say that at all. I did see it say that they take every legal advantage they can to claim the absolute highest range possible; no matter how unrealistic that may be. Most other manufacturers don't do that, instead choosing to claim a more realistic range.

The EPA really need to rethink this range calculation crap. I don't understand why the manufacturers get so much freedom to choose the vehicle's range.

Tesla years ago began exaggerating its vehicles’ potential driving distance – by rigging their range-estimating software. The company decided about a decade ago, for marketing purposes, to write algorithms for its range meter that would show drivers “rosy” projections for the distance it could travel on a full battery, according to a person familiar with an early design of the software for its in-dash readouts.

Then, when the battery fell below 50% of its maximum charge, the algorithm would show drivers more realistic projections for their remaining driving range, this person said. To prevent drivers from getting stranded as their predicted range started declining more quickly, Teslas were designed with a “safety buffer,” allowing about 15 miles (24 km) of additional range even after the dash readout showed an empty battery, the source said.

From the article.

Oh duh, the car display thing. I was just thinking of the EPA rated range for some reason, which doesn't really seem possible for them to defraud with.

I forget that the car even displays that range on the display since I changed mine to percentage the day I got it.

And Tesla can obviously predict range well, since they do such a good job with the navigation predicted arrival range. That has always been spot on for, like predicting my arrival percentage with in a percent or two even when I'm like 2 hours away.

The EPA doesn't test the EPA range, the manufacturer does. So it's entirely possible to cheat, and it's likely you've heard of some famous cases of cheating. Maybe a case involving VW and emissions?

Tesla's EPA estimate is the most out of line with real world tests whenever any independent organization tries to recreate the claimed range, and that shouldn't be a surprise to anyone given Teslas long history of bending the truth. They also have the most egregious "correction factor" for their range test that I've seen any manufacturer adopt.

I have a Mid Range Model 3, so it works out to 1% = 2 miles for me. But on this last road trip, I had the range estimate give me some wild predictions like 25% of the battery to go 100 miles. If I had followed the car's directions, there were two times I would have run out of charge miles from a charger.

After reading the details of the "range projection algorithm" it 100% explains the weird projections I was receiving.

When I first got my Model 3 5 years ago, the EPA "rated" range was 310 miles. Even in perfect conditions (70*F outside, no extra weight in car, driving 55 mph consistently, no launches, etc) I was never able to get more than 295 miles on a full charge. Then they pushed a software update to make the car more efficient and thus more mileage, but I saw no noticable difference. It's now saying 279 miles on a full charge after recalibrating the battery. I rarely ever charge past 90%. I still love the car though.

How is that not fraud? Explain it to me like I'm five.

[–] [email protected] 5 points 11 months ago

it should be. ford got in trouble for puffing up the mpg in their hybrids.

We own a 2021 Model 3 that we purchased second hand with 7.5k miles. Yes, performance is noticeably impacted in cold weather, especially below 40 degrees F. Tesla probably deserves the scrutiny and best on tenge estimates and claims and how it handles customer service issues. However, consumers can also educate themselves better on current EV battery performance issues in cold weather and what happens when all systems are blasted while driving over the speed limit. A lot of factors influence range performance whether it is an EV or ICE vehicle. We can identify with the quote at the end of the article.

“I do love my Tesla,” the engineer said. “But I have just tempered my expectation of what it can do in certain conditions.”
