The 2009 GMC Yukon offers professional grade engineering designed with the SUV driver in mind. With two powerful V8 engines to choose from--a 4.8L and a 5.3L Flex Fuel engine with Active Fuel Management (1)--this SUV takes you from strength to strength. A spacious, refined interior comfortably fits up to nine, and every Yukon come equipped with enhanced safety features including dual stage airbags (2), a tire-pressure monitoring system and one year of OnStar.

(1) FlexFuel engines are capable of operating on either gasoline or E85—a blend of 85% ethanol and 15% gasoline—or a combination of both. Ethanol fuel is a cleaner-burning, renewable fuel source made primarily from U.S. grown biomaterial such as corn or other grain products. (2) Always use safety belts and proper child restraints, even with air bags. Even with the Passenger Sensing System, children are safer when properly secured in a rear seat. See the Owner's Manual and child safety seat instructions for more safety information. Head curtain side air bags are designed to help reduce the risk of head and neck injuries to front and rear seat occupants. (3) OnStar services require vehicle electrical system (including battery), wireless service and GPS satellite signals to be available and operating for features to function properly. OnStar acts as a link to existing emergency service providers.
