Tesla has consistently exaggerated the driving range of its electric vehicles, reportedly leading car owners to think something was broken when actual driving range was much lower than advertised. When these owners scheduled service appointments to fix the problem, Tesla canceled the appointments because there was no way to improve the actual distance Tesla cars could drive between charges, according to an investigation by Reuters.
The big thing is the EPA estimate is a blend of city and highway driving. For ice cars the city is generally lower than highway, but it’s the opposite for most electric vehicles. I believe Tesla also uses 60 for highway speed instead of a more realistic 65-70+, the lower speed dramatically increases range.
Tesla vehicles just show the EPA range. Unlike every other EV out there, a Tesla vehicles doesn’t show the range factoring in weather, driving style and other factors in a guess-o-meter. They just show the EPA range times your battery %.
You only get the adjusted range when you plug your destination into the trip planner.
