Range penalty at freeway speeds

Had a unplanned test of range penalty with a 35-mi; trip on the LA freeways (freeway segment was about 27-mi.). Leaving home, I traveled at roughly 75 mph, and arrived at destination showing 49-mi loss in range. Returning home, at 65 mph, showed a loss of 30-mi.
The Soul-design drag costs energy at high speeds; no surprise.

More range loss than you would expect using velocity squared! Was there any headwind or altitude difference?

This makes no sense, you take a trip where you use more battery one way and not as much coming back and you blame the shape of the Soul?

What you stats say is that
- your destination may have been uphill and return on the downhill which of course affects battery range exactly that way
- going faster will use more battery than going a bit slower

This is nothing new, regardless of whether a car is battery or fossil fuel.
Going faster and uphill also burns fuel faster then a bit slower and downhill.
This affects all cars from boxy like Kia Soul or Land Rover to sleek like Tesla Model S or Audi R8.

Also you could have used regen drive mode B on the way back to get extra range.
