The 2016 GMC Yukon C1500 XL 2WD with the 5.3L V8 achieves 18 MPG combined. No one buys this extended-length Yukon expecting Prius-like mileage. It’s a dedicated hauler, designed for large families who need maximum passenger and cargo space, or for those who regularly tow boats or trailers. Fuel economy is a secondary concern, a necessary evil accepted for the Yukon XL’s immense capabilities.

City and highway performance

The EPA estimates the 2016 GMC Yukon C1500 XL 2WD at 16 MPG in the city and 23 MPG on the highway. Those figures reflect the Yukon’s significant size and weight, along with a traditional, even if proven, powertrain. The 5.3L V8 provides enough power for confident acceleration and towing, but it’s not the most efficient engine design. The six-speed automatic transmission, while generally smooth and reliable, also lags behind the fuel-saving capabilities of more modern eight or ten-speed units. Highway driving, with its consistent speeds, allows the engine to settle into its most efficient operating range, resulting in a noticeable MPG improvement over stop-and-go city conditions.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 GMC Yukon C1500 XL 2WD at $2,450. This figure is calculated based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also uses the EPA’s projection of national average fuel prices. Your actual fuel costs will vary depending on your driving habits, local fuel prices, and how often you use the Yukon XL’s full passenger and cargo capacity. Keep in mind, frequent towing will significantly increase your fuel consumption and drive up that annual cost.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy for the 2016 Yukon XL often differs. Expect to see numbers slightly below the EPA’s figures, especially if you frequently drive in heavy traffic, tow, or drive aggressively. However, careful and conservative driving can bring you closer to the advertised numbers. Maintain your vehicle, especially tire pressures and air filter changes, to keep efficiency optimized. Pay attention to YUKON MPG across all years to get an overall range of what drivers are reporting.

How it compares

Compared to its direct competitors, the 2016 Yukon XL’s fuel economy is typical for its class. The Ford Expedition EL, another extended-length, body-on-frame SUV, achieves similar MPG figures with its EcoBoost V6 engine. A four-wheel-drive Suburban 1500 model with the same 5.3L engine gets similar mileage. Smaller, more modern SUVs like the Honda Pilot or Toyota Highlander offer significantly better fuel economy – in the mid-20s combined – but they lack the Yukon XL’s immense space and towing capacity. For buyers who need the Yukon XL’s capabilities, the fuel economy trade-off is unavoidable, and it’s critical to be aware of the alternatives and understand the compromises involved.

Tips to maximize efficiency

Gentle acceleration and braking are key to maximizing fuel economy in the Yukon XL. The 5.3L V8 responds well to a light touch, and avoiding hard acceleration will prevent the engine from consuming excessive fuel. Use cruise control on the highway whenever possible. Maintaining a consistent speed minimizes unnecessary throttle adjustments and optimizes fuel consumption.

Keep your tires properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressures regularly, especially during temperature changes. A simple tire pressure gauge can save you money.

Minimize idling. Letting the Yukon XL idle for extended periods wastes fuel, especially with a large-displacement engine like the 5.3L V8. If you’re stopped for more than a minute or two, turn off the engine. This is particularly important in city driving where you may encounter frequent stoplights and traffic jams.

Reduce aerodynamic drag. Remove any unnecessary items from the roof rack and avoid carrying heavy loads unless absolutely necessary. A loaded roof rack or a trailer significantly increases aerodynamic drag, which reduces fuel economy, particularly at highway speeds. Planning in advance to minimize these loads can save you gas.
