I drove from home to, as far as Morgan Freeman's 'Ground Zero Blues Club', in Clarksdale, Mississippi, on the King Biscuit 50th- Anniversary International Blues Festival trip.
I ran the Bolt from 55-mph, to 75-mph, with the AC on, to experience the differences in range as the road load varied.
No pretense of 'scientific' data collection, as the trip was pure hedonism.
Texas, Oklahoma, Arkansas, and Mississippi, two-lane state highways, and Interstate-40, and 49.
The baseline numbers will help inform me in a couple of years, when I do something about the Chevy's shape.
For the trip, the car averaged 4.375-miles/kWh.
Cd 0.312 is not 'speed friendly.'
