This week, we’re getting behind the wheel of the 2021 GMC Yukon – Big Red’s thoroughly-redesigned full-size SUV. Built on the GM T1 platform shared with General Motors’ full-size pickup trucks – the Chevrolet Silverado and the GMC Sierra – and blessed with a new independent rear suspension, the Yukon boasts improved ride quality and enhanced handling characteristics. The model we’ll be driving is the rugged Yukon AT4.
Our 2021 GMC Yukon AT4 tester is equipped with the 5.3L L84 V8 engine (part of the EcoTec3 engine family) that features automatic engine start/stop and Dynamic Fuel Management to save some fuel. It’s managed by the GM 10-speed automatic transmission, which sends the V8’s 355 horsepower and 383 pound-feet of torque to all four wheels.
It also includes the AT4 Premium Plus Package that rounds up the features found in various individual option groups, such as the Premium Capability Package With Active Response 4WD System, the Max Trailering Package, the Technology Package and the Rear Media And Nav Package, along with a panoramic power sunroof, power-retractable assist steps, a power-sliding front center console and power-release, second-row bucket seats.
All that means this particular AT4 is equipped with the Adaptive Air Ride Suspension and the Magnetic Ride Control suspension system, the HD Surround Vision camera system, and all the hardware and software needed for towing safely and easily. The rig allows for a maximum towing capacity of 8,200 pounds (8,400 pounds in 2WD models).
We also get the GMC’s Active Response 4WD system that incorporates the AutoTrac two-speed transfer case, Traction Select drive mode control, StabiliTrak as well as an eLSD to optimize traction.
The 2021 GMC Yukon AT4 we’re driving is painted in Summit White – the only no-charge hue of the SUV’s ten-color palette. The cabin is dressed up in Jet Black, with perforated leather upholstery and brown contrast stitching.
Base price for the 2021 GMC Yukon is set at $51,995, which includes the destination freight charge, while an optioned-up Yukon XL Denali tops $86,345 before digging into the accessory catalog. Our AT4 rings in at $75,960 with options.
The Yukon AT4 will only stay with us for a very brief 24 hours. During this time, we’ll be looking at the overall quality, fit and finish, plus initial driving impressions.
