There's no sacrificing power, though. The 5.3-liter makes just over 300 hp in either standard or XL, the 6.0-liter is capable of 352 hp, and the 6.2-liter Denali has 403 hp under the hood. The Hybrid's engine and motor combine for a total of 332 hp. All Yukons are available in rear-wheel or full-time 4-wheel drive. In the base models, there are low-range gears for off-road use, while the Denali uses all-wheel drive for traction without the low range.
Safety features like head curtain airbags for all rows of seating are standard, as is stability control and ABS. A new tech feature for 2010 is USB connectivity in the console. Denali drivers get a few extras such as heated and cooled front seats and a power-tilt steering column. And for a little help in maneuvering this big beast with or without a trailer in tow, rear parking assist and backup camera are available.
