What a climb! Grenoble was at 250m and we climbed to 650m on the highway before turning off for the big climb. 16kms and 22 hairpins later and we were at 2065m in the ski resort.
We had 140kms (35%) of rated range at the bottom and 37kms (15%) at the top.
In addition, other cars were with chains or were sliding but we drive up with our 21″ summer tyres with no problem (except a small 4 wheel drift on one corner :).
And now it is in the garage and charging thanks to smittenbysnow.com.
Glad to have made it. So, you CAN cross Europe and go skiing in your electric car everyone!
