GMC Yukon XL 2021 for sale

GMC Yukon XL 2021

The 2021 GMC Yukon XL extended the standard Yukon's third-row and cargo space by 213 mm of additional wheelbase, making it one of the largest three-row SUVs in the Canadian market. The redesigned T1 platform introduced independent rear suspension — replacing the solid rear axle — fundamentally improving ride quality on Trans-Canada highway runs. The 5.3L EcoTec3 V8 with Dynamic Fuel Management at 355 horsepower is the volume powertrain; the 6.2L V8 at 420 horsepower and the 3.0L Duramax inline-six diesel are available on SLT and Denali. The Duramax diesel's fuel efficiency — approximately 10.2 L/100km combined — is the strongest argument for buyers who cover large distances across the Prairies or Atlantic Canada. DFM cylinder deactivation complaints from early 2021 production were addressed through GM calibration updates; confirm status on any 5.3L used example. The Yukon XL Denali with Magnetic Ride Control handles Manitoba's rough secondary roads with exceptional composure for a vehicle of its size.
