New for GMC’s 2009 Yukon is a 6-speed automatic transmission, replacing the standard 4-speed used in previous years and still available in base trims. Available in both RWD and 4WD versions, the Yukon boasts a not unimpressive 14/20 and 14/19 mpg rating from its 320-hp, 5.3-liter Vortec V8, especially when considering its nine-person seating, a towing capacity of more than 8,000 pounds, and flex-fuel capability option. A standard non-flex-fuel 5.3-liter is also available, and a 4.8-liter comes with the base trim, still putting out a respectable 295 hp and retaining the previous model year's 4-speed automatic transmission. All models have a gross vehicle weight rating of over 7,000 pounds.

Even so, with four-wheel ABS controlling its four vented discs, the Yukon isn’t short on stopping power. Coupled with a myriad of safety features including traction and stability control, a rear limited-slip differential, and electronic brake distribution, you won’t feel like you’re cruising around in a tank. Standard front and head-curtain airbags come standard in all four trim packages, as well as a tire pressure monitoring system and one year of OnStar, with level dependent on trim package.

All trims are available in RWD, while the SLE and SLT can be outfitted with a full-time 4WD system that is as at home on dry pavement as it is in the mud and snow and includes a low-range gear. Ride comfort has been noted as very car like, especially over bumps, with only slight float over dips and swells, with GM's Autoride load-leveling suspension doing its job. While still a large SUV, relatively little body lean or nose-plowing has been described in turns.

The Yukon’s spacious interior has been well-received across all trim levels, with high marks for fit and finish. Comfortable seats, whether bench or bucket, and ample headroom make for a fine ride, with over 60 cubic feet of space with all seats in place and almost 109 with the rear seat lying flat. Look for a new Dark Crimson Metallic color in 2009 as well.
