    How much energy do you gain from driving down Eagle Road, a steep mountain road descending into Geiranger, Norway, in a #Tesla Model S?

    no matter what, you used more juice going up than what you got back coming down...

    Mt Evans in Colorado is the highest Paved Road in North America at 14,130 feet and gives back 18 miles coming down.. IMG_2007.jpg

    I would expect a lot more, but then it's probably not all downhill.

    Anyways, yes, the car uses more energy going up, but any car does that. You just don't regain gasoline coming down a mountain in a gas car. That is where the difference lies

    About 30 times a year I go to a local ski resort that is 65 miles away, up hill all the way. The round trip generally uses 60% of my battery capacity, where I start out at 90% and return home at 30%. This is how the energy is consumed:
    • Going to the resort I use 50%
    • For the first 25 miles on the way back I have gained back 10%
    • At the next 10 miles I am back to the 60% I started the return trip with (having traveled 35 miles returning)
    • I use an additional 10% for the last 30 miles for the total round trip loss of 60%
    Only light regen braking is required unless traffic in front of me requires me to slow down more than the road dictates.

    You guys should check out @polywog. He drives Haleakala and logs his results. Probably has more info on this subject than anyone.
