In a word, great. When Tesla announced them other electric truck manufacturers called BS. Mercedes said the claimed range defied the laws of physics. Well, they seem to be doing what was claimed.
Pepsi has 21 of them (which I think it pretty much all of them right now). They seem to verify the claims. Tesla’s Giga Nevada is scaling up to produce more of them as well as batteries for them. The end of diesel trucking now seems possible.
