The GMC Yukon is shorter of the two GMC full-sized SUVs. Other divisions of GM sell variations as the Escalade and Tahoe. Inside, there are three rows of seats for up to 9 passengers depending on the equipped seating. The standard 5.3L V8 engine can tow over 8000 lbs. when properly equipped. Although full-size SUVs have become popular as family haulers, their only real advantage is higher tow ratings. 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 like the GMC Acadia. The Acadia offers similar legroom with improved maneuverability, cargo capacity and fuel efficiency for less money.

The new Yukon wears updated styling on a body that is longer and wider than the prior model. A 5.3l V8 rated at 320-bhp is standard on most models. Denali versions equip a more powerful 400-bhp 6.2l V8.
