In Europe the manufacturers are legally bound to quote the WLTP range. Which is hopelessly inaccurate.. But nowhere near as bad as the NEDC that preceded it. Of course people still come on forums wondering why they don't get <50% more than actually possible> out of their car, and I don't blame them.. the law is an ass.
TBF to Tesla though the in-car estimate is (I think) EPA and isn't far off.. It's doable in summer, at least. Winter you'll lose 30% but that's normal for all cars.
Many manufacturers get around this by quoting an estimated range and then the WLTP in small print ie. Highway Range: Est 415km in normal conditions (600km on WLTP cycle)
Hasn’t it been proven that the range can go longer but Tesla caps it? I remember during a hurricane Tesla said it was extending the range so drivers can make it out.
That’s not he projected range shown on the display. That’s the actual range the battery will give you.
They temporarily removed a bit of the safety margin built in to reduce battery wear, allowing people to get out of harms way without a stop to charge if they were on the limit. But only for people moving away from The affected area, etc. so smart and helpful.
Ah okay, thank you for the additional info.
I dislike both Tesla and Musk but as an automotive company I'd wager they have good safety factors on at least most of their engineering, so for example in the name of keeping the battery from degrading too fast the tesla probably stops drawing power from the battery when the battery voltage drops to a certian number. The safety factor just means that the number it shuts off at is likely a good bit before the batrery would theoretically start to take damage.
I can't find any other reason they would intentionally keep range off the product, because its not like they selling a solution to it. So I assume they probably just lowered the voltage at which the Tesla stops drawing power because getting stuck in the hurricane was obviously more dangerous. I could be wrong though, this is just from my expirences with bateries in engineering applications.
