The all-new 2007 Yukon XL and Yukon XL Denali full-size SUVs was announced by GMC at Los Angeles Auto Show. The line is led by the Yukon XL Denali, with unique styling and features - including a 6.2L V-8 engine that delivers the most horsepower in its class, with variable valve timing and a fuel-saving six-speed automatic transmission.
Yukon XL and Yukon XL Denali become available in the second quarter of 2006. The XL models have exterior dimensions similar to the regular models, but are about 14 inches (355.6 mm) longer in wheelbase and 20 inches (508 mm) longer in overall length. Yukon XL is available in SLE (cloth trim) and SLT trim (leather appointments), as well as 2WD and 4WD configurations and a heavy-duty model. A third-row seat is standard. A 5.3L V-8 with Active Fuel Management™ displacement on demand fuel-saving technology is standard. Later in the model year, a new 6.0L all-aluminum V-8 with Active Fuel Management and variable valve timing (VVT) becomes available; a 6.0L V-8 with VVT is offered in heavy-duty models.
Responsive suspension, solid chassis
The frame supports wider front and rear tracks - approximately 3 inches (76.2 mm) wider in front and 1 inch (25.4 mm) wider in the rear - that enhance stability and driving confidence through a more secure road feel and a lower center of gravity.
Seventeen-inch wheels are standard on Yukon XL, with 18-inch wheels standard on Yukon XL Denali. Twenty-inch wheels are available on Yukon XL and Yukon XL Denali. The wheels are designed with premium-appearance faces, including available chrome or polished finish. Yukon XL Denali wheels are exclusive. New tires are tailored to the vehicles to provide excellent balance of handling, quietness and safety.
New small-block V-8 family
A new Gen IV small-block V-8 family powers the new Yukon XL and Yukon XL Denali. Standard at start of production in Yukon XL models is a Vortec 5.3L V-8 with 320 horsepower (238 kw)* and 335 lb.-ft. of torque (463 Nm)*, which offers Active Fuel Management displacement on demand fuel-saving technology.
Heavy-duty models offer a 6.0L V-8 with VVT. It features an iron cylinder block and is rated at 350 horsepower (261 kw) and 360 lb.-ft. of torque (497 Nm). It is matched with a robust Hydra-Matic 4L80 four-speed automatic transmission.
The 6.2L engine of the Yukon XL Denali is all-new, too, with advanced technologies and lightweight materials, including VVT and an aluminum cylinder block, which helps the Yukon XL Denali delivering outstanding performance. The 6.2L engine is rated at 380 horsepower (283 kw)*, the most horsepower in its class, and 415 lb.-ft. of torque (564 Nm).
Like other Yukon XL models, the Yukon XL Denali offers several helpful and convenient options, including a navigation radio system, rear-view camera system, power sunroof, power-retractable assist steps (available mid-year) and a rear-seat, DVD-based entertainment system.
