Essentially GMC's version of the Chevy Suburban, the Yukon XL stretches the already long wheelbase of the Yukon another 20 inches.

The Yukon XL 2500 seats six to nine people and this heavy-duty version can tow up to 9700 pounds. It is rated for three-quarter ton and has truck tires with a heavier suspension using leaf springs. The standard 5.3-liter V8 offers excellent horsepower and torque. An optional 6.0-liter V8 for the Yukon delivers more towing power. The Denali trim has its own engine, a 6.2-liter V8 based on the Corvette's 7.0-liter, making 380 horsepower. The Yukon XL comes in two-wheel drive or four-wheel drive. Safety equipment on all models includes dual frontal airbags, four-wheel-disc anti-lock brakes with electronic proportioning, and StabiliTrak.

The GMC Yukon XL 1500 is all new for 2007.
