About GMC Yukon

The Yukon is a truck underneath, with a ladder frame and solid rear axle, and a truck powertrain and driving characteristics. Buyers can choose between a 5.3-liter 355-horsepower V-8 and a 6.2-liter V-8 with 420 hp. The smaller engine comes standard with a 6-speed automatic, while the larger engine gets a 10-speed automatic to help with fuel economy. The Yukon’s maximum towing capacity is a remarkable 8,500 pounds, and four-wheel drive is available, making it considerably more adept than any other crossover at carrying a boat or camper or going off-road.

The Yukon’s wide dashboard and high-quality materials make for a nice cabin on the inside, but with a starting price of more than $50,000, you should expect nothing less. On fleet-oriented variants, a bench seat is standard up front, but otherwise, two front bucket seats are separated by a spacious center console that can be ordered with a wireless charging pad.

The Yukon can seat up to six rear passengers, though room becomes increasingly limited as you travel back in the rows. With the third-row seat in position, the Yukon’s cargo capacity almost vanishes, so the larger Yukon XL is the better choice if you require space for more than five people and cargo. A high load floor also limits passenger and cargo room, and many crossovers are better at moving people and things for less money and less road space. All Yukons come standard with an 8.0-inch touchscreen, Apple CarPlay and Android Auto compatibility, and the option for GM’s outstanding 4G LTE in-car wi-fi system.
