The Yukon lineup was completely redesigned for 2007, and the Hybrid model was added for 2008.
The 2008 Yukon Hybrid has several styling cues that distinguish it from the other models. To reduce weight and drag, the front end features an aluminum hood, a lowered air dam, and a slightly larger grille opening. Openings that would house fog lights and tow hooks are blocked off. Along the sides, the running boards are reshaped for improved aerodynamics and the wheel flares are slightly reshaped. At the back, the rear pillars and center high-mounted stoplight have a unique shape, the tailgate is made of aluminum and has fixed glass, and LED taillights replace the standard bulbs. The wheels are more aero efficient and the tires have a lower rolling resistance. The spare tire and jack have been replaced by a tire inflation kit. The result is a 0.34 coefficient of drag and lighter weight. All of these measures add up and help improve fuel economy, if only by small amounts. Next Page
