23 MPG combined is a surprising figure for the 2023 GMC Yukon XL 2WD with the 3.0L Duramax diesel. This isn’t your typical fuel-sipping crossover; it’s a full-size, body-on-frame SUV designed to haul families, cargo, and trailers with strong capability. Thanks to the modern diesel engine and 10-speed automatic transmission, it achieves fuel economy figures previously unheard of in this class.

City and highway performance

The EPA estimates the Yukon XL 2WD diesel at 21 MPG in the city and 27 MPG on the highway. These numbers reflect the engine’s strengths. The diesel produces ample torque at low RPMs, which is ideal for navigating stop-and-go city traffic. The 27 MPG highway figure is particularly impressive, making it a relatively efficient choice for long road trips, a common scenario for Yukon XL owners. A family heading cross-country to visit relatives will appreciate the ability to cover significant distances between fill-ups, even with a loaded vehicle.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,400 for the 2023 GMC Yukon XL 2WD diesel. This calculation is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Naturally, individual fuel costs will vary depending on driving habits, local fuel prices, and the actual number of miles driven annually. However, the $2,400 figure provides a benchmark for comparing the Yukon XL’s fuel expenses to other vehicles in its class and against all Gmc fuel economy data.

Real-world expectations

While the EPA estimates provide a valuable reference point, real-world fuel economy can differ. Factors like aggressive acceleration, frequent towing, high speeds, and even tire pressure can impact MPG. Owner reports suggest that achieving the EPA’s 27 MPG highway figure is realistic under ideal conditions. However, city driving or towing often results in figures closer to the 21 MPG estimate, or even lower. Remember that the Yukon XL is a large vehicle with substantial weight, which inherently affects fuel consumption. Those who expect hybrid-like efficiency from this SUV will be disappointed.

How it compares

The 2023 GMC Yukon XL 2WD diesel sets a high bar for fuel economy in its class, but how does it stack up against the competition? The gasoline-powered Chevrolet Tahoe 2WD with the 5.3L V8 achieves a combined 17 MPG. The Ford Expedition 2WD with the 3.5L EcoBoost manages a combined 19 MPG.

Even the smaller, two-row Jeep Grand Cherokee 4xe plug-in hybrid achieves only 23 MPG combined when running solely on gasoline. Compared to these competitors, the Yukon XL diesel offers buyers prioritizing fuel efficiency without sacrificing full-size SUV capabilities. For a broader perspective, compare YUKON MPG across all years.

Tips to maximize efficiency

Gentle acceleration and braking are critical for maximizing fuel economy, especially with a large vehicle like the Yukon XL. The diesel engine’s torque allows for smooth and efficient starts without excessive throttle input. Anticipating traffic flow and avoiding abrupt stops can also significantly improve MPG.

Maintaining proper tire inflation is another simple but effective way to improve fuel economy. Check your tire pressure regularly and inflate to the recommended levels listed on the doorjamb sticker. Underinflated tires increase rolling resistance, which reduces fuel efficiency.

Reduce unnecessary weight whenever possible. Hauling extra cargo adds load to the vehicle, forcing the engine to work harder and consume more fuel. Remove any unnecessary items from the cargo area and roof rack when they are not needed.

Consider using cruise control on long highway drives. Maintaining a consistent speed helps to optimize fuel consumption. However, be mindful of terrain and adjust your speed accordingly, as excessive use of cruise control on hilly roads can sometimes decrease efficiency.

Regular maintenance, including oil changes and air filter replacements, ensures the engine runs optimally and contributes to better fuel economy. A properly maintained engine operates more efficiently, leading to improved MPG.
