The 2025 GMC Yukon XL 2WD with the 6.2L V8 engine delivers a combined 16 MPG. This figure is an expected cost for this vehicle. This is not a family hauler designed to sip fuel like a hybrid. This is a large, chrome-laden luxury vehicle built to transport up to eight adults and all their gear across long distances in comfort. Buyers are not comparing it to electric vehicles; they are comparing it to rivals with similar fuel consumption. They buy it for its commanding presence, towing capacity, interior space, and the rumble of that potent 6.2L V8. The fuel economy, while acknowledged, is a secondary consideration to its primary mission: capability and upscale presence.
City and highway performance
Breaking down that combined figure, the Yukon XL 2WD 6.2L returns 15 MPG in city driving and 19 MPG on the highway. In city conditions, the mass of the Yukon XL (which can exceed 6,000 pounds when laden) and the constant stop-and-go nature of urban grids naturally drive down efficiency. The 10-speed automatic transmission does its best to keep the rpms low, but physics remains a master. On the open road, the picture improves. At highway cruising speeds, the engine can settle into its most efficient operating range, and the expansive chassis provides a stable platform for long journeys. While 19 MPG might seem modest by sedan standards, for a vehicle of this size and power, it is a respectable figure. It allows for decent range between fuel stops, especially with the optional larger fuel tank. The character of the 6.2L V8 shines on the highway, with effortless passing power and a relaxed demeanor that eats miles without complaint.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2025 GMC Yukon XL 2WD 6.2L at $3,600. This calculation is based on an average of 15,000 miles driven per year and national average fuel prices. It is an important figure for perspective buyers, reflecting the reality of fueling such a large, powerful vehicle. While the initial investment in a Yukon XL is substantial, buyers must also factor in this ongoing operational cost. This isn’t just about the purchase price; it’s about the total cost of ownership, and for the Yukon XL, fuel will be a significant line item on the annual budget. Buyers of this vehicle understand that big vehicles with big engines incur big running costs, and they accept this as part of the privilege of owning a vehicle that fulfills such a specific, demanding role.

Real-world expectations
In real-world driving, many owners of the 2025 GMC Yukon XL 2WD 6.2L will find their mileage closely aligns with or falls slightly below the EPA estimates, depending heavily on driving habits. Aggressive acceleration, frequent towing, or consistently loading the vehicle to its maximum capacity will inevitably push the figures into the low teens. Conversely, a disciplined driver who practices hypermiling techniques and plans routes efficiently might occasionally see numbers closer to, or even momentarily exceed, the highway rating. The crucial factor here is the driver’s lead foot. That 6.2L V8 is addictive, and its copious power encourages spirited driving, which is the nemesis of fuel efficiency. Owners should expect to spend a considerable amount on fuel, but this is a conscious choice for the utility and luxury the Yukon XL provides.

How it compares
When stacked against its direct competitors, the 2025 GMC Yukon XL 2WD 6.2L’s 16 MPG combined is right in the thick of the full-size, V8-powered SUV segment. A comparable Chevrolet Suburban Premier 2WD with the same 6.2L V8 also boasts 16 MPG combined. The Ford Expedition Max with its 3.5L EcoBoost V6 typically hovers around 18 MPG combined in 2WD, showcasing the V6 advantage, but without the instant, linear power delivery of the large V8. Over in the luxury realm, a Cadillac Escalade ESV 2WD with the 6.2L V8 mirrors the Yukon XL at 16 MPG combined, as they share the fundamental architecture. Even the Toyota Sequoia, with its twin-turbo V6 hybrid powertrain, only manages 20 MPG combined for 2WD models. This is a noticeable improvement, but it does not offer the same classic V8 character or quite the same gargantuan cargo capacity. Buyers of the Yukon XL 6.2L simply are not settling for less power for a few extra MPG; they want the 6.2L.
Tips to maximize efficiency
Maintain consistent highway speeds whenever possible, allowing the 10-speed transmission to settle into its highest gears. Avoid rapid acceleration and hard braking, as these actions waste fuel and place unnecessary strain on the drivetrain. Use cruise control on flat stretches to prevent speed fluctuations.
Ensure your tires are properly inflated to the manufacturer’s recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check tire pressure regularly, especially before long trips.
Remove any unnecessary weight from the vehicle, such as heavy items stored in the cargo area or roof rack attachments when not in use. Every extra pound the engine has to move contributes to lower fuel economy. The Yukon XL is already a heavy vehicle; there is no need to make it heavier.
Plan your routes to avoid heavy traffic and excessive idling, where the Yukon XL’s city MPG struggles most. Combining multiple errands into a single trip can also reduce cold start fuel consumption, which is typically higher. Employ smooth, deliberate steering inputs to minimize wasted energy.
Keep up with the manufacturer’s recommended maintenance schedule, particularly oil changes, air filter replacements, and spark plug checks. A well-maintained engine runs more efficiently, ensuring that the 6.2L V8 is always performing at its peak.
