Can kill gas mileage too.
I’d like to see more data on that 20%~30% estimate if applied to a motorhome or a truck shaped like a box. I expect a much greater hit on range.
For example, that motorhome weighs roughly twice what a Tesla S weighs, and has roughly the same size battery. If driven slowly so rolling resistance was predominant energy consumption, then 249 miles of range versus Tesla at over 400 miles would make sense to me. However, the aerodynamic drag of that motorhome is probably more than twice what a Tesla S has, so if driven at steady 70 MPH on Interstate, I would expect range to take a much greater hit proportionally.
It’s similar to when someone (TFLT) tried pulling a trailer with Tesla SUV. Total weight more or less doubled, but range dropped to nearly 1/4 when at higher speeds. Granted, this Class C looks more aerodynamic than the trailer they used, but I’d still want to see data for motorhomes or trucks, not base it on aerodynamic automobiles.
