GMC's XL Denali is one of those vehicles where, if you have the money, a deep garage, and a desire for almost the ultimate in a luxury sport utility vehicle, you buy it.
The "almost the ultimate" is because this full-sized, three-row, seven-passenger SUV does not have all the glamour features of a luxury vehicle, such as power side window sunshades, a power cover for the power sunroof or massaging front seats.
Power inclusions though include fold and unfold third row, heated tilt and telescoping steering wheel, adjustable gas and brake pedals, perforated leather heated and ventilated (for air conditioning) front seats and retractable running boards. More ordinary power features include heated exterior mirrors, liftgate, door locks and remote start.
Memory settings are for driver's seat, outside mirrors, steering wheel, gas and brake pedals.
Suggested manufacturer pricing for a 2019 Yukon begins at $49,500. It is a rear-wheel SUV. Prices increase several thousands of dollars for four-wheel-drive. After Denali upgrade trim and safety features are added to the four-wheeler, the price is $66,600. When XL is added to the model name the price rises to $72,300. The XL means the Yukon is extra long and this is where it gets interesting.
A base Yukon is 203.9 inches long with third row leg room at 24.8 inches and cargo space at 15.3 cubic feet behind the third row. A Yukon XL is 224.4 inches long which means third row leg room has been upped to 34.5 inches and storage behind the rear seat increased to 39.3 cubic feet. Storage capacity also increases. After the third row bench and second row split seats (GMC also offers a bench seat in this row) have been folded flat, there are 121 cubic feet provided for storage purposes. This is huge. The carpeted floor surface is flat from lift gate to the backs of the front bucket seats.
Standard roof rails with $265 optional crossbars can hold 200 pounds of cargo.
The tested XL came with a 6.2-liter, 420-horsepower V8 engine mated to a 10-speed automatic transmission. It is the largest engine offered in GMC's SUVs. This powerplant is capable of towing an 8,100-pound trailer and carrying a payload of 1,610 pounds. This is impressive. One must remember that Yukon is an SUV and not a GMC Sierra full-size pickup truck where towing possibilities range from 9,500 to 23,300 pounds.
Mechanically, the Yukon XL Denali has automatic rear load leveling, trailer brake controller, two-speed transfer case, trailer sway control and fully automatic locking rear differential.
Without towing factored in, the tested Yukon averaged 17.1 miles per gallon in combined city and highway driving with two to four people aboard.
During the test week all occupants, young and old, male and female, registered compliments galore about the comfortable, quiet ride. "This thing is huge and wonderful," said a teenage girl to her sister, who agreed.
Seats, armrests and storage facilities are big. Cupholders are plentiful. Power outlets are 12 and 120 volts. Wheels and the tires are 22-inch.
Apple CarPlay and Android Auto are minor participants in a loaded infotainment system which also includes navigation. Smartphones can be charged while lying flat on the unopened front center console.
Navigation has options. Push a blue button to request directions from an advisor. Directions can be sent to the vehicle remotely by using the 'navigation' tab in the 'myGMC' app for compatible Apple and Android smartphones.
A unique feature is Marketplace, the auto industry's first in-vehicle commerce platform. Purchases and reservations can be made and the process is fairly simple.
Besides the Yukon, other large luxury SUVS are Chevrolet's Suburban, Lincoln Navigator, Land Rover Range Rover, Infinity QX80, Toyota Land Cruiser, Mercedes-Benz GLS- and G-Class, Lexus LX 570, and Cadillac Escalade.
