2007 Chevrolet Avalanche 1500 LTZ 4WD Road Test

Conceptually, Chevy's unique Avalanche is unchanged for 2007, though in appearance and engineering, much has changed. For starters, the vehicle is now founded on GM's new GMT900-series truck chassis, which also includes the handsome Yukon and Tahoe lines for 2007. Immediately noticeable is the integration of the front bumper into the Avalanche's front fascia. The redesign smooths-out the nose of the big rig, making it considerably more aerodynamic while reducing wind-rush and increasing fuel economy ever so slightly.
