GMC Yukon: 15/21 mpg (5.3-liter V-8) 14/18 mpg (6.2-liter V-8); 20/23 mpg (Hybrid)
the Yukon Hybrid does get better mileage — some 25 percent better than the non-hybrid Yukon overall, and up to 50 percent better in city driving
gulps fuel like an F-16, barely managing 14mpg in mixed city and urban-highway driving
Most of the 2013 GMC Yukon model line includes a 5.3-liter V-8; and the 15/21 mpg that these models achieve is unremarkable compared to other SUVs its size.
Yukon models with this engine are also E85 (85-percent ethanol) compatible; but when you fuel up with ethanol you'll get an EPA-estimated 11 mpg city, 16 highway.
Gas mileage drops to 14/18 mpg, or 13/18 mpg with all-wheel drive, when you upgrade to the 6.2-liter V-8 on XL versions and the Denali.
If those numbers give you pause, the Yukon Hybrid is likely to make you more satisfied; the Hybrid ekes out fuel economy ratings of 20/23 mpg, while it still can tow 5,000 pounds.
Most versions of the 2013 Yukon are unremarkable for fuel economy, but the Yukon Hybrid is one of the most efficient big SUVs on the market.
