The 2021 GMC Yukon has been completely overhauled, adopting a new platform, along with a new exterior design, a new cabin, and a new powertrain lineup. The all-new full-size SUV is also available with a wealth of safety and convenience features, such as the push-button actuated, Active Response Four-Wheel Drive system that allows the Yukon to be switched between two-wheel and four-wheel drive at any normal driving speed via the push of a button.
The buttons, intuitively located on the left side of the instrument panel, the 2021 GMC Yukon can be shifted from the standard 2WD high drive mode to the automatic 4WD high mode, suitable for varied conditions, and to the full time 4WD high mode, perfect for snowy conditions or most off-road use.
All of these modes may be initiated at any normal driving speed. The status of the Active Response Four-Wheel Drive system drive mode is displayed in the upper right of the driver information center.
Buyers who opt for the available two-speed transfer case will enjoy the advantages of a 4WD low setting. This allows the 2021 GMC Yukon to shift into or out of four-wheel drive low when the vehicle is stopped or moving at fewer than three miles per hour with the transmission in neutral.
The transfer case may be shifted into low after the instrument panel indicator light has stopped flashing. 4WD low is utilized for off-road driving in deep sand, mud, snow, or on steep hills.
Introduced by way of the world’s biggest tweet, the 2021 Yukon offers three engine choices, including two atmospheric gasoline motors and an optional turbo-diesel:
- 5.3L L84 gasoline V8 rated at 355 horsepower and 383 pound-feet of torque
