I am always starting at 100% as I charge at home and at work. For this commute I typically arrive to work at 68/69% battery and estimated 2.7mi/kwh efficiency rating. Today I had the ability to come in late so I decided to focus on efficiency above all else. I drafted an 18 wheeler at a close but safe distance for virtually the entire ride at between 66 and 70mph, no A/C (front flaps closed), no cruise control. Zero electric braking. I was pleasantly surprised that I arrived to work, mildly sweaty, with 82% battery, 4.2mi/kwh. By reducing the speed approximately 20%, the car was 56% more efficient. At least is my HS math is correct anyway.

1) On the Chevy Bolt, if the old national 55-MPH speed limit constituted 'one-car's ' worth of energy consumption:
2) By 73-mph she'd be consuming two-cars worth.
3) At 84-mph, three-cars.
4) And, at 93-mph, four-cars.
It really 'tells' on the velocity-cubed relation to aerodynamic power needs.
5) At 45-mph, the BOLT will go over 496-miles on the 'recall', 66-kWh pack.
6) At 45-mph, the IONIQ 5 will go 546-miles.
7) At 45-mph, the IONIQ 5, with the IONIQ 6 body, will go 638-miles.
8) At 45-mph, the IONIQ 5, with the GM Aero 2002 body will go 769-miles.
9) At 45-mph, the IONIQ 5, with Cambridge University Eco Racer ( CUER ) 'Revolution' body, will go 844-miles.
