As @RickMachE said, there is a lot of information in this forum to help you. This is a really good place to start:
You haven't lost anything. Tesla's "estimated range" is an overestimate, the Mach E's is an underestimate that gets more conservative as it gets colder.
That‘s because Teslas don’t dynamically estimate their remaining range. Instead, they just show the rated range for the given battery percentage. The car won’t really go that far, but it keeps people happy because they get to see a big number. Based on the number of threads like this, it’s clearly working.
sad but true
Set departure times in the car. So if you leave for work at 8:00am each day, then set the departure time for 8am. That way #1 your car will be nice and warm on the inside, and #2 it will get the battery to the temperature to give you the best efficiency possible.
Are you talking about real range or just the GOM reading on the left side of the instrument panel?
Meanwhile they increased the EPA rating in various models. That's unlikely to change the real world highway cruise range though, since the EPA rating includes speed changes.
