Chevy engineers have obviously put a lot of work into the 2007 Avalanche’s powertrains and features, but what prospective buyers will notice first is the updated styling. The new front end, with smoked headlights and a clean wrap-around grille, is shared with the new Tahoe, the track has been widened front and rear for a more aggressive stance and improved handling, and tighter gap tolerances accent the truck’s appearance. Inside is a redesigned dash, a simpler and more attractive center console, all built with higher quality plastics.
