The one-piece front end presents a friendly, welcoming face but without forfeiting the Yukon's presence. Large headlight housings promise good vision. The trademark grille and lower air intake ensure good breathing. A sharply raked windshield eases movement through the air.

Tall, symmetrical side glass fits flush with surrounding body panels. Door handles bridging deep recesses make for easy gripping in all seasons. Squared-off wheelwells carry forward a Yukon signature styling cue. They suggest trimming up with the available 20-inch wheels and tires, though that's not our choice from a driving and towing perspective.

At the rear, a broad, mostly flat, almost vertical tailgate resides between tall, narrow taillights. The independently hinged rear window is a nice touch, permitting easy loading of grocery bags and such.

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 The spare tire and jack have been replaced by a tire inflation kit.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.
