A while back, I proposed to the Bolt Forum that they use the conversion formula from foot-pounds to kwh to figure loss of range when climbing hills and mountains. Several tried it and reported fairly accurate numbers. So, it's anecdotal but reasonable.
The formula is change in elevation (ft) x (weight of vehicle + cargo and people (lbs)) * 3.76616e-7 = kwhrs used. So if a Bolt weighs 3500 pounds and you add two adults plus cargo and it's driven up a 1,000 foot grade, that's 1,000 * (3500 + 400) * 3.77*e-7 = 1.47 kwhrs In other words, you lose about 6 miles of range for a vehicle that normally goes 4 miles on a kwh of electricity.
