This near twin version of the Chevrolet Tahoe uses a 5.3-liter V8 and six-speed automatic that returns 16 mpg and doesn't feel particularly energetic. Ride and handling are not stellar, although the Magnetic Ride Control suspension on the Denali version improves ride comfort and handling response. The 6.2-liter engine that comes on the Denali is also a meaningful upgrade, but it raises the price considerably. Proper optional equipment gives the Yukon a towing capacity of 8,500 pounds, about the only advantage it has over a car-based SUV. Just as in the Tahoe, the third-row seat is low and tiny. Automatic emergency braking, blind-spot monitoring, and lane-keep assist are optional. Reliability has been well below average.

The 2015 redesign brought a sumptuous and quiet interior, power folding second- and third-row seats, and available advanced safety features. Top-trim Denali versions offer a larger V8 and plusher interior furnishings. We think it's important to get the Magnetic Ride Control suspension, because it significantly improves the Yukon's emergency handling, as well as ride comfort. Lower trim lines without this feature have sloppy handling in emergency situations. Getting that suspension, however, requires going all the way to a Denali. In all honesty, other than that, we'd skip the GMC altogether. You can get the Magnetic Ride Control in a top LTZ-trim-level Chevrolet Tahoe without the big engine. That will cost you less money and consume less fuel.

The 2007 redesign brought a better ride and improved steering, along with a much nicer interior. However, the third-row seats lack thigh support and don't fold flat into the floor, eating up cargo room. The powertrain we tested, a 5.3-liter V8 with the six-speed automatic transmission, was strong enough -- but unrefined. Controls are mostly simple, but some are tiny and too far from the driver.

This twin of the Chevrolet Tahoe shares a platform with the other full-sized GM trucks. It has strong, fuel efficient engines, as well as a more comfortable ride. ESC was offered starting with 2003 models, preventing tip-ups in government rollover tests.
