16 MPG combined is the reality for anyone considering the 2024 GMC Yukon XL 2WD with the 6.2L V8. This isn’t a number that will win any awards, but it’s a price many buyers are willing to pay for the immense space, towing capability, and effortless power that this extended-length SUV provides. This vehicle is designed for a specific mission: hauling large families, towing boats or campers, and dominating road trips with comfort and confidence. Acceptable fuel economy is secondary, if still a consideration.

City and highway performance

The EPA estimates for the Yukon XL 6.2L 2WD break down to 14 MPG in the city and 19 MPG on the highway. The city figure reflects the engine’s displacement and the vehicle’s considerable weight, which demands more fuel for stop-and-go maneuvers. The highway number, while not stellar, benefits from the 10-speed automatic transmission that allows the engine to cruise at lower RPMs when cruising on the open road. These figures highlight that this Yukon XL performs best on longer, less congested drives.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2024 GMC Yukon XL 2WD 6.2L is $3,600. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a significant expense, and one that’s critical for prospective buyers to factor into their budget. A quick look at all Gmc fuel economy data will reveal that this model rests near the bottom of the pack in terms of efficiency.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy can vary considerably. Factors like driving style, terrain, and cargo weight all play a role. Aggressive acceleration, frequent hard braking, and consistently hauling heavy loads will decrease fuel economy, potentially dipping below the EPA’s estimates. Conversely, a smooth, steady driving style on flat terrain could yield slightly better results, but don’t expect miracles. Owners should carefully track their MPG through each fill-up. A quick look at the YUKON MPG across all years page reveals a consistent history for this nameplate’s fuel consumption.

How it compares

Compared to its competitors, the Yukon XL 6.2L’s fuel economy paints a clear picture. The Ford Expedition Max with the 3.5L EcoBoost V6 achieves a slightly better 17 MPG combined. The Chevrolet Suburban, mechanically similar to the Yukon XL, offers identical MPG figures (16 MPG combined). A Toyota Sequoia, with its hybrid powertrain, gets a combined 22 MPG. However, the Sequoia trades some towing capacity for that increased efficiency. Ultimately, the GMC Yukon XL’s fuel economy is a known compromise for those who prioritize its blend of power, space, and traditional SUV capabilities. The buyers consider these facts and still opt for the Yukon XL due to brand loyalty, features or towing capacity that trumps fuel savings.

Tips to maximize efficiency

Despite its V8 engine, there are ways to improve fuel consumption in the Yukon XL 2WD. The first is to drive smoothly and deliberately. Avoid abrupt acceleration and braking, which waste fuel. Anticipate traffic flow and maintain a steady speed whenever possible.

Consider using the Yukon XL’s drive mode selector. If your model has a specific “Eco” or “Tour” mode (check your owner’s manual), engage it when appropriate for daily commuting. This mode typically adjusts throttle response and shift patterns to prioritize fuel efficiency.

Proper tire inflation is critical. Check your tires regularly and maintain the recommended pressure listed on the tire placard (usually found on the driver’s side doorjamb). Under-inflated tires increase rolling resistance and reduce fuel economy.

Reduce unnecessary weight. Hauling around heavy cargo that isn’t needed adds to the vehicle’s workload and decreases fuel economy. Remove any items from the cargo area that are not essential for your trip.

Finally, keep up with routine maintenance. A properly maintained engine runs more efficiently. Follow the manufacturer’s recommended service schedule for oil changes, air filter replacements, and spark plug maintenance.
