Lots of threads and consternation about recent firmware affecting the car's range and efficiency. Oddly, it only affects a subset of owners. Any chance that the folks who are affected have the new wheel configuration set to the less efficient wheel choice? We know that new firmware now offers Wheel Configuration under the Service tab. Obviously, this will input distinct efficiency rate constants depending on wheel choice. I'm guessing that people who have seen their rated range suddenly drop a few percent have the larger diameter rim chosen. So maybe no CLASS ACTION this week?
