I live in Denver and I was curious about the impact of elevation change on the range of the Bolt. I drove up to Rocky Mountain National Park and back. Here's what I got.

The temp was 62F in the early morning when I started and 48F at Bear Lake trail head, 67.4 miles away. I started from 5,500 ft elev and parked at 9,450 ft, a climb of 3,950 ft. The Bolt used 18 kWh for an average of 3.7 mi/kWh.

For the return trip, the temp was 71F at the trail head and 85F in Denver. Going down the hill used only 6 kWh over 68 miles for an average 11.3 mi/kWh on the return leg. Overall, the car displayed an average for the trip at 5.6 mi/kWh.

The most interesting part was that I used 0 kWh for the first 40 miles since leaving the trail head! I was in Lyons, CO, at an elevation of 5,400 ft when the energy used went above what it had been at the starting point at the trail head. It took 6 kWh to travel the remaining 28 miles and climb 100 ft. Roughly 1/4 the cost of gas for my ICE car to make that trip. Amazing car!
