How quick it is

Under the hood of the 2006 Cadillac Escalade EXT is a 6.2-liter V8 pushing 403 horsepower at 5,700 rpm and twisting out 417 lb.-ft. of torque at 4,400 rpm. Premium fuel is recommended, and a six-speed automatic transmission distributes power through the Escalade EXT’s all-wheel-drive system. Active Fuel Management, the displacement-on-demand fuel-saving technology available on similar Chevrolet and GMC engines, is absent on the Cadillac, though if your shopping list consists of 400-horsepower luxury trucks, chances are fuel economy isn’t at the top of your list anyway.
