Even the new Tesla S model ranges are reported at 55 mph instead of 65 mph, which makes a great deal of difference because air resistance goes up in the third power of speed.Any figures you see in the media, especially for cars that have not yet gone through EPA testing, add 50% and you get close to what they really do. 300 Wh/mi is still extremely optimistic.ReplyDeleteBrett_cgbNovember 18, 2012 a
