Rough calculations (to be published later in detail): it took all cars about 3x the energy to climb Pikes Peak (20 miles up, but 60-70 miles of range consumed). Going back down you to 2:1 returned (20 miles down and over +20 miles recaptured).
Brake temps were 51, 53, 54, 58 and 60 F.
Note: The amount of data captured is too wide to show on this blog. If you'd like a copy of the spreadsheet showing the information, just email Wilson Hitchings and I'll send you a copy!
