Looks custom designed to me. As a rule most car model typefaces are.

Yves is right of course, but you could get kind of close to this by playing around with Serpentine Sans.

These people seem to have a custom avalanche font, although I can’t seem to see it. It looks to be only windows compatible:

Yves is right, it was probably custom designed for chevy, so the font is probably someone’s homebrew like you would find on fontface.com. It probably won’t be an exact match, but close.

Thanks for all your help guys! 8)
