Took Sam the Tesla up Mt Evans earlier today. Super easy drive in the new MS 70D although a little crowded on the road. Even with serious incline almost all the way out to the top of the mountain (approx 80 miles from home. 160 miles round trip) the car still showed approx 110 miles range available when I got home. Very Impressive. Firmware was updated to the latest yesterday, any evidence that its helping with extended range?
