We’re talking Queen Mary 2 here as GMC reveals the all new the 2021 Yukon and Yukon XL, upping the ante by offering class-leading technology, an AT4 version and a turbo-diesel, an engine I loved in my recent GMC Sierra test.

Power, what are my options?

The most powerful engine in the full-size SUV segment, is the all-new 6.2L V8 with Dynamic Fuel Management (standard on Denali) delivers an estimated 420 horsepower, paired with a standard 10-speed transmission. The base engine is the is an all-new 5.3L V8 producing 355 horsepower and 383 pound-feet of torque. or you can opt for the excellent 3.0-liter straight-six turbo diesel with 277 hp and a stonking 460 lb-ft of torque. Both V8s feature stop/start and cylinder deactivation that lets them run on as few as two cylinders. Also available is a First-in-class, four-corner Air Ride Adaptive Suspension systems for improved ride comfort. When 4WD LOW is engaged, the driver can raise the body up to 2 inches (50 mm) for additional ground clearance when traveling off-road.

Speaking of off-road an all-new available Active Response 4WD System combines technologies including an electronic Limited Slip Differential, to continuously monitor road conditions and react to improve traction, handling and overall control.

Is it Bigger?

Both the Yukon and Yukon XL have grown, measuring almost five inches longer between the axles and offering more than 20 additional cubic feet of max cargo room compared to the outgoing version. If you need more space, it’s available by the acre.

Inside View

The Denali comes with a completely new instrument panel, unique seats and a choice among four unique color themes, including authentic wood trim, with a fully natural look and texture.
