New GMC Yukon Full-Size SUVs for Sale in Sudbury, ON

The GMC Yukon is one of the largest SUVs on the road, and that shows up in the numbers. It stretches over 5.3 metres in length, and the extended GMC Yukon XL goes even further. That extra size is not just for presence. It directly affects how much space you get inside. There is room for three full rows of seats, with usable cargo space behind them. That is something many smaller SUVs claim to offer but cannot match in practice.

Those dimensions also influence how the GMC Yukon is used. It is a vehicle that suits long journeys, larger families, and situations where space and capability matter more than convenience in tight urban settings. At the same time, GMC has refined the way the GMC Yukon is equipped and structured. The lineup now splits into distinct paths: AT4 models focus on capability, and Denali models on refinement, each leading to a fully equipped Ultimate version.

Popular GMC Yukon Trim Levels

The GMC Yukon lineup in Canada begins with Elevation and moves through AT4, AT4 Ultimate, Denali, and Denali Ultimate. Each trim adds more equipment and a higher level of finish, but the structure is built around purpose rather than price alone. AT4 models are designed for off-road use, while Denali models focus on comfort and technology. Ultimate trims sit at the top of each path and include the most complete specification.

• AT4: The AT4 is where the GMC Yukon starts to show its capability. It comes standard with four-wheel drive and a two-speed transfer case. All-terrain tires, skid plates, and hill descent control are all included. The suspension and front-end design also support better approach angles when the road runs out.
• AT4 Ultimate: The AT4 Ultimate takes that same hardware and adds a much higher level of finish. It brings in the 6.2-litre V-8 engine, along with Magnetic Ride Control and Air Ride Adaptive Suspension. Inside, you get full leather seating, heated and ventilated front seats, and a more detailed, premium interior throughout.
• Denali Ultimate: The Denali Ultimate is the most complete GMC Yukon available. It uses the 6.2-litre V-8 and focuses on refinement rather than off-road use. The interior uses full-grain leather and real wood trim, and it adds features such as Super Cruise and a 22-speaker Bose audio system.
• Other Trim Levels: Elevation and Denali trim levels complete the lineup. Elevation is the starting point with a 5.3-litre V-8, large displays, and strong standard equipment. Denali builds on that with upgraded materials, more technology, and a more premium feel without reaching the Ultimate level.

GMC Yukon Key Features

The GMC Yukon combines traditional full-size SUV strength with a modern approach to comfort and technology. It still uses a body-on-frame platform, which supports serious towing. At the same time, it now places much more emphasis on interior quality and technology. Large displays, advanced suspension systems, and driver-assist features all play a bigger role than before. The result is a vehicle that still works hard but also feels far more refined than many rivals.

• Engine and Fuel Economy: The standard engine is a 5.3-litre V-8 producing 355 horsepower and 383 lb.-ft. of torque. A 6.2-litre V-8 is available with 420 horsepower and 460 lb.-ft. of torque. The 3.0-litre Duramax diesel produces 305 horsepower and 495 lb.-ft. of torque. All engines use a 10-speed automatic transmission. Four-wheel drive is standard on AT4 models and available across the range.
• Seating and Cargo Capacity: The GMC Yukon is a proper three-row SUV comfortably accommodating up to eight people. Second-row captain’s chairs reduce seating to seven. Front legroom measures 1,133 mm, with 1,064 mm in the second row and 886 mm in the third row. Cargo space measures 722 litres behind the third row. That increases to 2,056 litres and 3,480 litres with the rear seats folded.
• Technology and Connectivity: Every GMC Yukon comes with a 16.8-inch infotainment touchscreen. An 11-inch digital driver display sits ahead of the steering wheel. Google built-in supports navigation, apps, and voice control. Apple CarPlay and Android Auto are standard. Higher trims add a 22-speaker Bose audio system and available rear-seat entertainment screens.
• Safety and Driver Assist: Forward collision alert with automatic emergency braking is standard. Lane-keeping assist and lane departure warning are also included. Adaptive cruise control and blind-zone steering assist come standard. Higher trims add HD surround vision, rear pedestrian alert, night vision, and Super Cruise hands-free driving.
