With the standard engine the 2011 Yukon can move quite quickly, and its six-speed automatic transmission provides rapid acceleration and good responsiveness. All Yukon SUVs can be ordered with available four-wheel drive. A single-speed transfer case system is standard on Yukons; a two-speed transfer case is an option on Yukon and Yukon XL; and Denali editions come with on-demand four-wheel drive.
On all versions, the steering feels light but not communicative, and bumps are positively smothered by the massive curb weight and big coil-spring suspension. The GMC Yukon Denali models all get GM's Autoride electronically controlled damping system, which does a great job bringing good ride comfort and decent steering response through the big 20-inch wheels. Overall, the Denali isn't tremendously maneuverable, but it handles surprisingly well on back roads; you'll quickly forget that you're piloting a 6,000-pound vehicle that can tow up to 8,600 pounds.
