How we work this out
Each answer drives the real road route in 30-meter steps: speed, climbs and descents (with regenerative braking), rolling resistance, cabin heating or cooling, a cold battery's lower capacity, and the typical wind. Temperatures are NOAA 1991–2020 climate normals for each place along the way. Every car is calibrated to its EPA highway rating. Each car starts at 90%.
