Though not necessarily ready for the NASCAR circuit, the redesigned 2007 Chevrolet Avalanche comes with ample power for the street. Two-wheel-drive versions draw power from a 5.3-liter V8 pushing 320 horsepower and 340 lb.-ft. of torque, while the four-wheel-drive Avalanche gets the same motor with 310 horses and 335 lb.-ft. of twist. Both are E85 compatible, feature GM’s Active Fuel Management displacement-on-demand system for fuel savings, and are connected to a four-speed automatic transmission. A 6.0-liter V8, with Active Fuel Management but not corn-fed, will be released after the truck’s spring 2006 launch.
