For 2009, a host of new features is designed to deliver segment-leading fuel economy and give customers more choices of helpful safety and convenience equipment. The new features include a fuel-saving six-speed automatic transmission on models equipped with the 5.3L and 6.0L engines, Bluetooth wireless phone connectivity, XM Satellite Radio with new NavTraffic feature and more. The new content adds to an already comprehensive package of performance, safety and comfort features that gives customers unparalleled choices in the segment.

The new Hydra-Matic 6L80 six-speed automatic enhances fuel economy on the highway via reduced engine speed. The engine requires less fuel to operate at a lower "cruising" speed. Also, quietness in the interior is enhanced with the lower-rpm cruising.

Yukon Denali and Yukon XL Denali are also back for 2009, packing the same helpful technologies as the Yukon models, as well as an enhanced 6.2L V-8 that is more powerful and E85-capable. Denali models also receive additional comfort and convenience features.

Yukon rides on a 116-inch (2,946 mm) wheelbase, with an overall length of 202 inches (5,130 mm). It rides on a wider track that, along with the long wheelbase, provides a smooth, confident and secure driving experience. Yukon XL models have exterior dimensions similar to the regular models, but are about 14 inches longer in wheelbase and 20 inches longer in overall length. Both Yukon and Yukon XL are available in SLE (cloth trim) and SLT trim (leather appointments), as well as 2WD and 4WD configurations. A third-row seat is standard on all Yukon models.

Yukon and Yukon XL models feature a 5.3L V-8 with GM's fuel-saving Active Fuel Management technology. A 4.8L V-8 is the standard engine on the Yukon 2WD base model only, and a 6.0L all-aluminum V-8 with variable valve timing is available on Yukon XL. Several available engines are capable of running on E85; in fact, all Yukon 4WD and Yukon XL half-ton models come standard with the E85-capable version of the 5.3L V-8. GM vehicles with E85 capability can run on 100 percent gasoline, E85 or any combination of the two.

2009 GMC Yukon Hybrid
The GMC Yukon Hybrid delivers a dramatic improvement in fuel economy over non-hybrid models - up to a 50-percent improved mileage in city driving - with all of the comfort and capability customers expect in a full-size SUV. There is no difference in passenger seating capacity, and towing and payload are highly competitive with other non-hybrid SUVs in the segment.

The Yukon Hybrid's vastly improved fuel economy over gasoline-only siblings is due largely to a s tate-of-the-art hybrid system using GM's all-new Electrically Variable Transmission (EVT). Two-wheel-drive Yukon Hybrid models, for example, deliver 21 mpg in the city, a 50-percent improvement over their 5.3L non-hybrid siblings and comparable to the much smaller, 2008 2.4L-equipped Toyota Camry sedan.

An industry first for any full-size SUV, the patented hybrid system allows the Yukon Hybrid to return exceptional fuel economy in both city and highway driving while still delivering full-size SUV performance. Imagine a full-size SUV that offers 25- to 30-percent more combined city-highway fuel economy while also providing up to 6,200 pounds (2,812 kg) of usable towing capacity (2WD) and 6,000 pounds (2,722 kg) on 4WD models; 12,000 pounds (5,443 kg) GCWR and eight-passenger seating capacity. Making all this possible is GM's advanced EVT and 300-volt nickel-metal hydride Energy Storage System (ESS), which work in concert with the standard 6.0L V-8 gasoline engine with Active Fuel Management (AFM) and late intake valve closing (LIVC) technology. GM's new hybrid system not only enables the Yukon to launch and drive up to 30 mph on electricity alone, it also allows the 6.0L V-8 engine to operate in its more economical V-4 mode for longer periods.

New exterior colors - Dark Crimson Metallic is offered on Yukon and Yukon XL; and Carbon Black Metallic replaces Dark Slate Metallic on the Denali.
