23 MPG combined is a surprising number for the 2022 GMC Yukon XL 2WD with the 3.0L Duramax diesel engine. This isn’t a compact crossover, it’s a full-size, extended-length SUV designed to haul families, cargo, and even tow trailers with ease. Buyers considering the Yukon XL prioritize space, capability, and comfort above outright fuel efficiency, but 23 MPG helps them justify the purchase without feeling too guilty at the pump.

City and highway performance

The EPA estimates break down to 21 MPG in the city and 27 MPG on the highway. That highway figure is particularly impressive for a vehicle of this size, and it’s where the Duramax diesel shines. Its abundant torque allows it to cruise effortlessly at highway speeds, using minimal fuel. In city driving, the stop and go nature naturally reduces efficiency, but the 10-speed automatic transmission helps keep the engine in its optimal range.

Annual fuel cost

The EPA estimates that the annual fuel cost for this particular Yukon XL configuration is $2,400. This figure is based on driving 15,000 miles per year, with an assumed fuel price based on national averages. Your actual fuel costs will vary depending on your driving habits, location, and current fuel prices. However, $2,400 provides a benchmark for comparing the Yukon XL’s running costs to other vehicles in its class. The EPA calculates the annual fuel cost by multiplying estimated fuel consumption for 15,000 miles (based on combined MPG) by the projected national average price of fuel.

Real-world expectations

While the EPA estimates provide a valuable baseline, real-world fuel economy can vary. Factors like cargo weight, passenger load, towing, driving style, and terrain all impact MPG. Owners who frequently tow or drive in hilly terrain will likely see lower fuel economy numbers than those who primarily drive on flat highways. However, drivers who prioritize smooth acceleration, consistent speeds, and proper tire inflation can often achieve results close to or even slightly exceeding the EPA estimates. The diesel engine tends to reward longer trips with more efficient operation as it reaches its optimal operating temperature.

How it compares

The 2022 GMC Yukon XL 2WD Duramax compares favorably to its gasoline-powered counterparts and direct competitors. The standard 5.3L V8 in the Yukon XL 2WD achieves a significantly lower 17 MPG combined. Even the smaller, standard-length Yukon with the 5.3L only manages 18 MPG combined. The Chevrolet Tahoe, being mechanically similar in the 2WD configuration with the same diesel engine, posts identical EPA figures of 21 city, 27 highway and 23 combined. The Ford Expedition, which has more powerful but less fuel-efficient EcoBoost engines, comes in around 17 MPG combined in its 2WD configuration. These differences are meaningful for budget-conscious families who need a large SUV for space, not outright performance. If looking for competitor vehicles check all Gmc fuel economy data.

Tips to maximize efficiency

Optimize your highway driving by using cruise control whenever possible. Maintaining a consistent speed not only improves fuel economy but also reduces driver fatigue on long trips. The Yukon XL’s diesel engine prefers a relaxed pace; avoid aggressive acceleration and sudden braking to minimize fuel consumption.

Regular maintenance is critical for optimal fuel efficiency. Ensure your tires are properly inflated to the recommended pressure, as underinflated tires increase rolling resistance and reduce MPG. Also, keep up with scheduled oil changes and filter replacements to keep the engine running smoothly. Consider exploring YUKON MPG across all years for insights from other owners.

Minimize unnecessary weight. The Yukon XL can haul a lot, but every extra pound contributes to increased fuel consumption. Remove any unnecessary cargo from the vehicle, especially heavier items, to improve MPG, particularly around town.

Use the Yukon XL’s driver information display to monitor your fuel economy in real time. Observing your MPG during different driving conditions can help you identify areas where you can adjust your driving habits to improve efficiency.

While tempting, resist the urge to accessorize the Yukon XL with large roof racks or other aftermarket accessories that negatively impact aerodynamics. These additions create more drag, which reduces fuel economy, especially at higher speeds.
