The Yukon XL is GMC's long wheelbase full-sized SUV. Other divisions of GM sell variations as the Escalade and Suburban. Inside, there are three rows of seats for up to 9 passengers depending on the equipped seating. Compared to the shorter-wheelbase variant Yukon, the Suburban is some 20 inches longer in overall length. Most of the length is behind the second row seats nearly doubling the cargo capacity behind the third row. The standard 5.3L and 6.0L V-8 (3/4 ton models) engines have cylinder deactivation technology to allow the engine to run on 4-cylinders under light load conditions. Although full-size SUVs have become popular as family haulers, their only real advantage is tow ratings of over 7500 lbs. Full-size SUVs with truck underpinnings are robbed of interior space with the body mounted over the frame. Most families would be better served with a crossover SUV such as the GMC Acadia. Many offer similar legroom with improved maneuverability, cargo capacity and fuel efficiency for far less money.

What Changed:

The 3/4 ton model is not available for 2014.
