2020 GMC Yukon
Though the familiar design is now entering its seventh year, the full-size 2020 GMC Yukon SUV is still as spacious, capable, and elegant as ever. The 2020 Yukon is available in both standard and long-wheelbase variations. The long-wheelbase model, known as the Yukon XL, rides on a 14-inch longer wheelbase than the standard-length model. Overall length is up 20.5 inches. The stretch yields significantly more cargo space and third-row legroom.
As an old-school SUV, the Yukon gets old-school V-8 power. Most models come standard with a 5.3-liter V-8 that makes 355 horsepower and 383 pound-feet of torque, but a 6.2-liter V-8 is also available. This engine puts out a full 420 hp and 460 lb-ft of torque.
The smaller engine continues to use a 6-speed automatic, but the 6.2-liter sends its power through a 10-speed automatic. Rear-wheel drive is standard across the range, though four-wheel drive is available. Properly equipped, this SUV can tow a full 8,500 pounds.
Expect 15 mpg city, 22 mpg highway, 18 mpg combined for a rear-drive Yukon with the 5.3-liter V-8. Four-wheel drive drops that to 15/21/17 mpg. The 6.2-liter engine improves highway gas mileage over the base powertrain, almost certainly due to the more efficient 10-speed automatic and its higher final-drive ratios. This engine is good for 15/23/17 mpg in RWD spec and 14/22/17 in 4WD trim.
Fuel economy for the longer Yukon XL models are nearly identical to the standard-length models.
The NHTSA gives the Yukon a four-star overall rating.Some trims offer adaptive cruise control and automatic emergency braking.
