23 MPG combined is an impressive figure from the 2023 GMC Yukon 2WD equipped with the 3.0L Duramax diesel. This isn’t a compact crossover sipping fuel; this is a full-size SUV built for hauling families, towing campers, and tackling long road trips in comfort. Reaching that MPG figure in a vehicle this capable is a notable achievement in engineering and efficiency.

City and highway performance

The 3.0L Duramax diesel’s fuel economy breaks down to 21 MPG in the city and 27 MPG on the highway. The city figure illustrates the diesel’s ability to efficiently manage stop-and-go traffic, using its torque to minimize throttle input. The highway number is where the Yukon shines, though. 27 MPG allows for extended cruising range, reducing fuel stops on those long family road trips. The 10-speed automatic transmission plays an important role here, keeping the engine in its optimal efficiency range at various speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 GMC Yukon 2WD 3.0L 6-cyl at $2,400. This figure is based on driving 15,000 miles per year, using a blend of city and highway driving, and assumes national average fuel prices. While individual spending will depend on how and where the Yukon is driven, this provides a solid point of reference for potential owners and facilitates easy comparisons to competing vehicles. Considering the Yukon’s size and capabilities, this number represents a reasonable compromise for many buyers.

Real-world expectations

It’s important to understand that EPA estimates are benchmarks, and real-world fuel economy can vary. Factors like driving style, terrain, load, and weather conditions all impact fuel consumption. Expect slightly lower MPG numbers if you frequently tow heavy loads or drive aggressively. Drivers with a gentle foot and consistent highway travel might exceed the EPA estimates. The Yukon’s onboard trip computer provides real-time and average MPG data, allowing drivers to monitor their fuel consumption and adjust their driving habits accordingly.

How it compares

The Yukon’s diesel puts it in a unique position compared to its gasoline powered competitors. The standard 5.3L V8 gasoline version of the Yukon gets just 17 MPG combined. Even the smaller Cadillac Escalade, sharing the Yukon’s platform, with its 2WD and standard 6.2L V8, also gets 17 MPG combined. A similarly equipped Ford Expedition with its 3.5L EcoBoost V6 manages around 19 MPG combined. For buyers prioritizing fuel economy without sacrificing full-size SUV capabilities, the Duramax diesel Yukon is noticeably more efficient, especially over long distances.

Tips to maximize efficiency

Take advantage of the Yukon’s drive modes. The “Normal” mode is generally the most efficient for everyday driving. Avoid using “Sport” mode unless you truly need the extra responsiveness, as it will impact fuel consumption.

When weather conditions impact driving, use 4-wheel drive sparingly.

Gentle acceleration and braking are key to maximizing fuel economy in any vehicle, but this is especially true for the Yukon. The Duramax diesel delivers plenty of torque at low RPMs, so you don’t need to push the engine hard to get moving. Anticipate traffic flow and maintain a consistent speed whenever possible.

Regular maintenance is essential for optimal fuel economy. Ensure your tires are properly inflated, as underinflated tires increase rolling resistance. Stick to the recommended maintenance schedule for oil changes and air filter replacements. A well-maintained engine runs more efficiently.

Minimize aerodynamic drag by removing any unnecessary items from the roof rack, as they can significantly reduce fuel economy, especially at highway speeds. Closing the windows at higher speeds also helps reduce wind resistance. The Yukon’s size makes it susceptible to wind resistance, so reducing it will help conserve fuel.
