With 320 horsepower and 335 lb.-ft. of torque under the hood, the Vortec™ 5.3L V8 engine gives you up to 8,100 lbs. of towing muscle† to add to the 137.4 cu. ft. of maximum cargo space†.
Active Fuel Management™ technology delivers power when you need it and conserves it when you don't. When you're driving on level roads, the system automatically deactivates four of the eight cylinders. It then reactivates all cylinders when you accelerate or travel on inclines.
