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 5500 lbs. (8500 with towing package). One advantage the full-sized GM SUVs (Escalade/Tahoe/Yukon) have is the availability of a hybrid powertrain. Fuel Economy in the Yukon Hybrid jumps to 20/23 (city/highway) while still maintaining a 5000+ lb. tow rating. Unfortunately the hybrid powertrain is a pricey upgrade costing over $10,000. 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.
