@alexluttrell It would only reduce the 250-mile range to about 240:
They say the extra width reduced drag "over 10%". Since they're playing it UP, it's fair to assume it wasn't MUCH over 10% though. That would make the drag coefficient about 0.144 which adds less than 0.2kW at 48mph (9.62mi/kWh instead of 10.0)
@Ken Kobayashi Sure, but even at 15%, with just 25kWh it's still some 588% of the average daily drive at around 235 miles. Need more, get the bigger battery, or the illegal-width model if you're allowed.
