The 2024 GMC Yukon XL 4WD with the 6.2L V8 gets 16 MPG combined. This vehicle isn’t bought for its fuel efficiency, but for its immense size. People buy it for its ability to tow substantial loads, its strong V8 power, and its capacity to comfortably haul a large family plus all their gear. The fuel bill is simply a cost of doing business.
City and highway performance
The EPA estimates city driving at 14 MPG and highway driving at 18 MPG. Achieving these figures will depend heavily on driving style. The temptation to tap into the plentiful power of the 6.2L V8 is ever-present, which hurts fuel economy. The 10-speed automatic transmission helps keep the engine in its most efficient range when cruising, but it’s still fighting against the Yukon XL’s mass and aerodynamic shortcomings. Expect the MPG to be even lower than the EPA estimates in stop-and-go city traffic.
Annual fuel cost
The EPA estimates an annual fuel cost of $3,600. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel cost will vary depending on how many miles you drive annually and the price of gasoline in your area. Aggressive driving habits and frequent towing will also significantly increase your fuel expenses. For context, $3,600 per year is roughly the cost of tuition for a community college course or a high-end home theater system.
Real-world expectations
While the EPA provides a standardized way to measure, real-world experiences often differ. Owners of the 6.2L Yukon XL, especially those who regularly tow or drive in hilly terrain, frequently report fuel economy figures lower than the EPA’s 16 MPG combined. Conversely, those who primarily use the Yukon XL for long highway trips and adopt a conservative driving style might see slightly better results, but even then, surpassing 20 MPG is rare.
How it compares
The Yukon XL’s fuel economy places it firmly at the lower end of the full-size SUV spectrum. A similarly equipped 2024 Chevrolet Suburban with the same 6.2L V8 delivers virtually identical fuel economy. Stepping down to the Suburban or Yukon XL’s 5.3L V8 engine will improve fuel economy by a modest 1-2 MPG in combined driving. For buyers prioritizing fuel efficiency, a Ford Expedition with its 3.5L EcoBoost V6 achieves around 17 MPG combined, but those looking for massive displacement often avoid that option. You can also review all Gmc fuel economy data to see how even more recent models stack up regarding real-world MPG. Finally, YUKON MPG across all years can provide helpful comparisons.
Tips to maximize efficiency
Despite the limitations of a large V8 SUV, there are still ways to optimize fuel economy in your Yukon XL. The 10-speed automatic transmission will shift quickly into the higher gears if you’re gentle with the accelerator, so avoid sudden bursts of speed whenever possible.
Tire pressure is important for fuel efficiency. Ensure your tires are properly inflated to the recommended pressure listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, leading to lower MPG.
Reduce unnecessary weight by removing cargo and gear that you don’t need to lighten the load and improve fuel economy. This is important if you frequently use the Yukon XL as a family hauler.
Consider using cruise control on long highway trips. Maintaining a consistent speed can help minimize fuel consumption. Engaging “Tour” mode can optimize settings for highway efficiency and fuel saving driving habits.
Be mindful of your driving habits. Aggressive acceleration, hard braking, and high speeds all contribute to poor fuel economy. A smoother, more relaxed driving style will not only save fuel but also improve overall comfort and safety.
