The 2017 GMC Yukon K1500 XL 4WD with the 6.2L V8 gets 16 MPG combined. This truck is built for a specific mission: hauling large families, towing substantial loads, and providing a comfortable, premium experience. Gas mileage is a consideration, but it’s not the main reason people buy it. Buyers stepping into this Yukon XL know they are trading efficiency for capability and sheer size.

City and highway performance

The EPA estimates 14 MPG in the city and 20 MPG on the highway. The city figure reflects the demands of stop-and-go traffic on a heavy vehicle, where the 6.2L V8 constantly works to get the mass moving. The highway number, while still not stellar, demonstrates the engine’s ability to cruise at a relatively relaxed pace. The 8-speed automatic transmission helps optimize the engine’s performance at various speeds, playing a critical role in managing fuel consumption. These figures are EPA estimates determined in laboratory conditions. They are useful for comparison, but your actual mileage will vary.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2017 GMC Yukon K1500 XL 4WD 6.2L V8 will be $2,750. This figure is based on driving 15,000 miles per year, with a specific percentage of those miles driven in city versus highway conditions, and using a national average fuel price. The number allows potential buyers to understand that operating this large SUV involves a significant expenditure on fuel, one that should be carefully considered in the overall ownership budget.

Real-world expectations

Don’t be surprised if your real-world fuel economy falls slightly below the EPA estimates. Factors like driving style, terrain, and cargo weight affect consumption. Frequent towing will drastically reduce MPG figures. On the other hand, careful use of cruise control on long highway stretches might yield slightly better results. Understanding the factors that influence fuel efficiency is key to managing expectations for this powerful, but thirsty, SUV.

How it compares

Compared to other full-size SUVs in 2017, the Yukon XL 6.2L’s fuel economy is about what you’d expect. The Ford Expedition with its 3.5L EcoBoost V6 offers slightly better EPA numbers, around 17 MPG combined for the 4×4 version. A similarly equipped Chevrolet Suburban, sharing the same platform as the Yukon XL, will deliver similar MPG figures. The Nissan Armada, with its 5.6L V8, might return even lower numbers. The important point is this: Buyers considering the Yukon XL aren’t solely focused on fuel economy. They prioritize interior space, towing capacity, and a premium driving experience, all attributes where it excels. You can review YUKON MPG across all years to see how this model compares to others.

Tips to maximize efficiency

The 6.2L V8 offers impressive power, so learn to modulate the throttle. Aggressive acceleration consumes fuel rapidly. Smooth, gradual starts and maintaining a steady speed can make a noticeable difference over time. Anticipate traffic conditions to avoid unnecessary braking and acceleration.

Regular maintenance is critical. Ensure the engine is properly tuned, and that tires are inflated to the correct pressure. A well-maintained engine runs more efficiently. Low tire pressure increases rolling resistance, forcing the engine to work harder and consume more fuel.

Consider the weight you’re carrying. The Yukon XL is designed to haul, but unnecessary weight contributes to lower fuel economy. Remove any items from the vehicle that aren’t needed for your journey. Unnecessary cargo adds load, making the engine work harder, especially in city driving.

Minimize idling time. If you anticipate waiting for more than a minute, turn off the engine. Excessive idling wastes fuel and contributes to unnecessary emissions. Modern engines are designed to restart easily, making it more efficient to switch off the engine in situations where prolonged idling is unavoidable.

Use cruise control strategically on the highway. Maintaining a consistent speed, particularly on flat terrain, can optimize fuel consumption. However, disengage cruise control when driving in hilly areas, as the system may aggressively downshift to maintain speed, which reduces fuel economy. If you want to research all Gmc fuel economy data, that information is readily available.
