    The 2021 GMC Yukon is a full-size SUV designed for those who want a complete driving experience that's roomy, comfortable, smooth, and offers plenty of cargo space for travel. While this luxurious and capable vehicle has been a part of the GMC lineup for decades, it has been redesigned from the ground up for the 2021 model year and now offers more space and more features than ever before. With solid towing capabilities and more-than-capable performance for a full-sized vehicle, the 2021 GMC Yukon is designed for discerning drivers looking for an SUV that isn't just about providing conventional functionality but also has an air of refinement to its style as well. There is even an extended-length variant, the Yukon XL, for drivers who need even more passenger and cargo space. It is time to take a detailed look at everything the all-new 2021 Yukon and Yukon XL bring to the table.

  • Performance & Capability

    A black 2021 GMC Yukon is driving down a mountain road while towing an airstream trailer.

    The 2021 GMC Yukon is designed to handle passengers, cargo, and towing. It comes equipped with a powertrain setup that produces enough performance on the highway to ensure the driver and passengers have a smooth, steady ride no matter where the plotted destination is located. The Yukon comes standard with a 5.3-liter V8 engine that produces 355 horsepower and 383 pound-feet of torque. The engine is paired with a 10-speed automatic transmission and has engine start/stop technology to help optimize fuel efficiency.

    Engine Options

    Alternatively, if you want more power and performance out of the 2021 GMC, there is the option to equip the Yukon with a 6.2-liter V8. The larger V8 produces 420 horsepower and 460 pound-feet of torque, complete with dynamic fuel management in order to boost gas mileage and reduce fuel consumption. New to the 2021 model year is a 3.0-liter inline six-cylinder Duramax turbo-diesel engine that generates 277 horsepower and 460 pound-feet of torque, providing drivers with plenty of torque and better fuel economy.

    Range and Efficiency

    The Yukon contains a fuel tank capacity of 24 gallons, while the larger Yukon XL features a 28-gallon tank. This gives the Yukon plenty of range even when pulling a trailer. The standard V8 engine provides up to 16 miles per gallon when driving through the city and up to 20 miles per gallon while driving on the highway. Upgrading to the larger V8 maintains the same highway mileage and only drops the city efficiency slightly to 15 miles per gallon. Finally, the 3.0-liter Duramax diesel engine nets you an impressive 21 miles per gallon in the city and up to 27 miles per gallon on the highway.

    The Yukon and Yukon XL are designed to provide passengers with plenty of moving space and cargo capacity. The Yukon seats up to eight people and measures 210 inches in overall length, offering a cargo volume of 122.9 cubic feet behind the first row, 72.6 cubic feet behind the second row, and 25.5 cubic feet behind the third row.


    The Yukon XL sits on a larger wheelbase and measures 225.2 inches in overall length, providing additional cargo and passenger space within the interior. There is up to 144.7 cubic feet of cargo volume behind the first row, 93.8 cubic feet behind the second row, and 41.5 cubic feet of cargo volume behind the third row. However, it still seats a maximum of eight passengers, albeit in greater comfort.

    Payload and Towing

    As far as payload and towing capacity goes, the 2021 GMC Yukon has a maximum payload capacity of up to 1,792 pounds. If you plan on using the Yukon for towing or trailering, all versions of this full-sized SUV come equipped with standard trailering equipment, including a hitch platform, a 2-inch trailer receiver, and a 7-wire electrical harness with a 7-pin connector for the trailer lights and brakes. With the Max Trailering Package, Yukon owners can pull up to 8,400 pounds.

    New trailering technologies have also been included, such as high-definition surround vision to help improve parking, backing up, and aligning the trailer with the Yukon. Trailer profile pages are also available, allowing drivers to customize which type of trailer is hooked up to the vehicle. The system also provides tire pressure and temperature monitoring as well as blind-zone alert systems so that you always know where the trailer is in relation to Yukon at all times.

  • AT4 Trim

    For those who want both luxury and off-road capabilities in one package, the GMC Yukon's new AT4 off-road trim combines the traditional comfort features of the full-sized SUV with all of the durability and performance capabilities one would expect from an off-road 4x4. The Yukon AT4 is designated as a premium off-road trim that comes with a completely redesigned front fascia and features specially configured suspension modifications to accommodate off-road traversal, including a 2-inch increase in total ground clearance compared to the standard Yukon. It even includes Goodyear all-terrain tires on large 20-inch wheels.

    Off-Road Features

    A two-speed transfer 4x4 case provides maximum traction in difficult terrain, along with a traction selection system so you can modify how the Yukon performs off-road. This is all thanks to the Active Response 4x4 System and the advanced chassis control mechanism that works in cohesion with the Air Ride Adaptive Suspension. What all of this means is that there are up to four inches of ride height adjustments that take place while you drive in order for the suspension to adjust the vehicle to undulations in the terrain, ensuring that the vehicle delivers the smoothest ride possible.

    The suspension is further secured with the Magnetic Ride Control, which makes use of magnetorheological dampers, which are based on a fluid-based shock system that hardens around the piston to absorb bumps and shunts based on electronic sensors that monitor changes in the ride behavior and road conditions. Combined with the electronic limited-slip differential, traction is never lost on the Yukon since the sensors always ensure that the vehicle maintains steady momentum and balance. If a wheel is detected to have lost traction, the torque is transferred to the other wheels in order to improve overall traction for the Yukon.

    Luxury Features

    The Adaptive Air Ride Suspension also enables lower ride height during high-speed travel and for when passengers embark or disembark from the Yukon. Additionally, skid plates are part of the AT4 package to protect the undercarriage during the raising and lowering of the vehicle while engaged in off-road activity. The AT4 trim rounds out with a heated steering wheel, ventilated front seats, heated second-row seats, leather upholstery, and a custom jet black interior theme with Brandy accents.

  • Technology

    GMC has maintained vigilance with keeping its line of trucks and SUVs up-to-date with the latest in technology, and this amply applies to the 2021 Yukon as well. The utility vehicle features a 10.2-inch diagonal multi-color infotainment touchscreen, which comes standard on all available trims and configurations. Among the additional tech systems is an optional rear camera mirror that allows drivers to use a camera to provide a wide-area angle of what's behind the Yukon with fewer artifacts and obstructions to impede clarity of the view. For comfort, there is a power tilt and telescoping steering wheel and a 10-way power-adjustable driver seat.


    Infotainment features include the GMC Connected Access portal with OnStar navigation and emergency assistance support. For entertainment, you have HD radio and SiriusXM Satellite Radio with a 360L trial subscription and an available rear-seat media system that includes dual 12.6-inch LCD touchscreens with Wi-Fi wireless projection capability. Of course, no luxury SUV would be complete without Apple CarPlay and Android Auto integration, complete with wireless connectivity for media streaming. This allows drivers and passengers to easily access data, information, and media content on their Apple smart devices or Android tablets and phones.


    On the safety side, there are lots of included functions and standard features for the Yukon, such as multiple airbags for drivers and passengers. Front and rear parking assist can detect nearby objects to help guide the Yukon into tight spaces and comes standard on all trims, along with tire pressure monitoring to inform drivers when the tires need more air and automatic emergency braking.

    Alert systems are also standard on all trims, including forward collision, front pedestrian braking, and front outboard passenger sensing for frontal outboard passenger airbag deployment. Other assistance features include lane change alert with side blind-zone coverage, lane keeping assistance, lane departure warnings, rear cross-traffic alerts, and teen driver mode.

    An electrical theft-deterrent helps protect the Yukon from unauthorized entry and will immobilize the engine to prevent theft. This is in addition to other security features such as a steering column lock that can only be released with the appointed key fob.
