Agreed on the high altitude power with battery. I expect it to be almost like a turbo because the lack of air isn't a problem for the electric engine. My worry is that at 10K feet, the naturally aspirated portion of the engine looses about 30% of it's power (3% per 1000 feet). So, if the battery is out and the 200hp is more like 140hp. Going uphill with the heavier 2008 might get pretty sluggish.

I talked to sales people in the Front Range and at this point, they are not willing to let me test drive it that far. They say they will "sign papers" saying I could return it if I'm not satisfied with the performance. Not sure I like the idea. I think that the Colorado law forces them to do that anyway if I'm not mistaking (3 days/ 250 miles).

Thanks for your input.
