LeafSpy rounds to the nearest mile, otherwise has been accurate to +/-.1 with the dash efficiency for my trips over 50 miles.
Thanks for this, I saw on one of the EV efficiency sites that Teslas are rated as the most efficient but they are only rated at about 25 kWh/ mile or 4 miles/kWh........ not uncommon for Leafs to get this or better, even tho Leafs are listed well down the list for efficiency. Which poses the question: what is the real-world efficiency of electric vehicles? we know Leafs from our own experience and from people sharing on this forum, are there Tesla owners here who can share actual data? is it possible that Tesla has technology that makes their motors more efficient, or do they cook the books somehow?
