Actually who's to say, not many people tow with a Tesla Model 3 or their SUV, Be curious as far as the Hummer, Lightning and Rivian P/U'sLike most info on EVs it's not easy to pin down a number on how much heat affects range. Read where AAA said as much as 41% decrease . But Elon disputed it and said not nearly that high. But didn't offer an alternative number.
