GMC Yukon XL

This truck-based SUV is a twin of the Chevrolet Suburban. The third-row seat in the XL is a bit roomier than the one in the shorter GMC Yukon, and there is plenty of cargo room when that row is raised. Power comes from a 5.3-liter V8 and a six-speed automatic that returns 16 mpg and feels slightly sluggish. It's too bad that you have to opt for the expensive Denali version to get the Magnetic Ride Control suspension, which improves ride comfort and handling response. The 6.2-liter engine on the Denali is also a meaningful upgrade, but it significantly increases the price. Properly equipped, the XL can tow 8,500 pounds, its only advantage over a car-based SUV. Lane-keeping assist and Apple CarPlay capability are available.

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 stronger V8 and plusher interior finishes. The Yukon XL is exceptionally quiet, in fact, it's a lot like a good luxury car. Handling is sound and responsive enough, with no excessive body lean, but the feeling of bulk is ever present. Adaptive cruise control, blind spot warning, rear cross-traffic alert, forward collision and lane departure warning are available. Choosing the top Yukon XL Denali trim with its Magnetic Ride Control improves the ride significantly, pays dividends in handling, but gets very pricey. Instead, we'd opt for the Suburban LTZ over the Yukon XL. That model pairs the Magnetic Ride Control suspension with the more efficient 5.3-liter engine, which is a combination unavailable from GMC. Changes for 2016 include available lane-keeping assist.

The 2007 redesign brought more agility, better steering and brakes, and a more responsive six-speed automatic transmission. The interior was also significantly upgraded, but the third-row seats lack thigh support and don't fold into the floor.

The Yukon XL is a clone of the Chevy Suburban. It can seat up to nine people and haul massive cargo loads or tow a 10,000-pound trailer. The Yukon XL handles commendably and its brakes work well. It also has a well-controlled ride. ESC arrived in 2003.
