Escalade buyers can now choose between an ever-capable all-wheel-drive model and a less expensive two-wheel-drive model. You must spring for all-wheel drive to get the giant, Escalade-exclusive high-compression Vortec 6000 V8, which makes 345 horsepower and 380 ft-lbs. of torque. An enhanced version of the current 6.0-liter used in three-quarter- and 1-ton full-size Chevy and GMC trucks, this engine shares its basic architecture with the LS1 V8 found in the Corvette. Two-wheel-drive models have a 5.3-liter powerplant that pours out 285 horsepower and 325 ft-lbs. of twist. Both engines use a heavy-duty version of GM's top-notch 4L60-E four-speed automatic transmission. The all-wheel-drive model can tow up to 8,500 pounds, while two-wheel-drive Escalades can lug up to 6,600. The Cadillac also handles well given its size, and we think it is at least as pleasant to drive as any other luxury SUV
