Big trucks need big power, a point capably addressed by the 2007 Cadillac Escalade’s 6.2-liter, 16-valve, aluminum V8 pushing 403 horsepower at 5,700 rpm and 417 lb.-ft. of torque at 4,400 rpm, the same powerplant squeezed into the ESV and EXT versions. A six-speed automatic transmission is mated to the big Vortec engine, and features a tow/haul mode as well as a button for manual shifts – simply drop the column-mounted shifter into M and tap the switch to change gears.
