My Model Y gives two mileage estimates simultaneously - a ballooned EPA estimate and an accurate (typically within 1%!) estimate once I put in a destination. The latter is usually ~75% of the former.<p>At first this felt like typical marketing BS. But I also find my inner engineer defending it a bit - the range depends significantly on top speed and head/tail wind. If I slow down to 60 mph on the interstate I have exceeded the stated EPA mileage.<p>I get the confusion and frustration, but at the same time the claimed range is under ideal conditions, just like every other manufacturer. But because the Tesla is so much more energy efficient, deviations feel magnified.
