Expert Quotes:

GMC Yukon and Yukon Denali feel surprisingly fleet of foot. No, really!
Road & Track

Yukons are muscular off the line and in highway passing/merging

it's not quite as vibrant when passing
Kelley Blue Book

Transmissions provide crisp, timely shifts

steering, although precise, is too light for such a large vehicle

With two body styles, three trim levels, and three basic engine variants, the Yukon's performance envelope could be unmanageable-but all versions have good acceleration and ride quality, light steering, little if any handling feedback (they're huge trucks, after all), and pretty dismal fuel economy.

Standard-issue 2010 GMC Yukons offer a standard 5.3-liter V-8 with 320 hp in the shorter Yukon and 310 hp in the longer Yukon XL. Both of the smaller V-8s have plenty of torque to move the Yukon with authority, even with a full load, and fuel economy is quite respectable for such a huge vehicle, with ratings of 14/20 mpg from the EPA. Jalopnik reports the "Vortec V8 gives you a much power as you need, whenever you need it." ConsumerGuide agrees: "Yukons are muscular off the line and in highway passing/merging with the 5.3-liter V8." A special Yukon XFE edition has the same power output as the smaller base SUV, but with a taller transmission final-drive ratio for better fuel economy, at 15/21 mpg.

The Yukon XL and both Denali editions offer a 403-hp, 6.2-liter V-8, as an option on the XL and standard on either the Yukon Denali or the Denali XL. It's the pick for the toughest towing demands and accelerates smartly with a rich engine note, but mileage will only reach 12/19 mpg at most, even with new cylinder-deactivation technology applied. There's plenty of reserve power for hills, quick passing maneuvers, and full loads. ConsumerGuide doesn't think it's so different from the rest of the Yukon engine lineup; it says the "Denali's 6.2 feels only slightly stronger" than the other powerplants.

A single six-speed automatic transmission is offered across the Yukon lineup, one with "shift lever buttons for manual operation," ConsumerGuide points out. In all applications, the six-speed automatic shifts smoothly but responsively. Kelley Blue Book says its "responses are less harsh than in [previous] models, with less-noticeable delays." ConsumerGuide reports the transmission provides "crisp, timely shifts."

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. Cars.com explains the Denali's permanent 4WD is "distinct from the available part-time four-wheel drive on the regular Yukon."

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 Yukon lineup boasts impressive handling for a vehicle of this size and pedigree, although it's not universally praised. Edmunds reports the "Yukon's steering, although precise, is too light for such a large vehicle." Kelley Blue Book contends that "ride quality...is hardly truck-like at all, and it feels secure in curves." ConsumerGuide also praises the "car-like comfort over bumps," and they note "long-wheelbase XL models are slightly more comfortable regardless of tire choice."

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. Road & Track even reports that the "Yukon Denali [feels] surprisingly fleet of foot," with the "taut, well-tuned chassis [feeling] more car-like than truck-like in operation." Kelley Blue Book calls the 2010 GMC Yukon Denali "by far the best handling full-size SUV ever to wear a GMC badge," though ConsumerGuide isn't quite so impressed with the ride quality, stating that "impact harshness over sharp bumps is exaggerated by the short sidewalls of the available 20-inch tires." Braking is another strong point; ConsumerGuide says the "brakes offer no-drama stopping control with solid pedal feel." Jalopnik confirms "the four-wheel disc brakes worked with aplomb" during their road test. 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-"strong towing and hauling capabilities," as Edmunds describes it.

How does the
TCC Rating work?
The TCC Rating is a clear numeric rating value based on a 10-point scale that reflects the overall opinion of our automotive experts on any vehicle and rolls up ratings we give each vehicle across sub-categories you care about like performance, safety, styling and more.

Our rating also has simple color-coded “Stop” (red), “Caution” (orange),
or “Go” (green) messages along with the numerical score so you can easily understand where we stand at a glance.

Our automotive experts then also collect and show you what other websites say about these different aspects of any vehicle. We do this leg work for you to simplify your research process.
