Powertrain Options and Availability
Yukons and Yukon XLs have come with a variety of V8 powertrains. A 4.8-liter V8 has been standard in the Yukon SLE. Other regular-length Yukons held a standard 5.3-liter V8. A 6.0-liter V8 has been optional in Yukon XLs. Denalis contain a 6.2-liter V8 that generates 380 horsepower. Four-speed automatic transmissions are used in all models except the Denali, which gets a six-speed automatic. Denalis came only with all-wheel drive; other models could have either rear-drive or four-wheel drive. The Yukon Hybrid, introduced for 2008, uses a 320-hp version of the 6.0-liter V8, coupled to an electric motor. Note that the Hybrid gets the same 20-mpg EPA fuel-economy estimate in both city and highway driving, a result of its gas/electric powertrain.

1. EPA Note: Figures shown are for 2008 models. The Environmental Protection Agency changed its procedure for 2008 to yield more realistic estimates. Therefore, estimated mileage is lower than for prior years. 2. V8/electric Specifications Key: NA = not available; "--" = measurement does not exist. |
