The 2021 GMC Yukon 2WD with the 6.2-liter V8 gets 17 MPG combined. Nobody buys this Yukon expecting Prius-like efficiency. This is a large, body-on-frame SUV designed to haul families, tow boats, and generally dominate the road. Fuel economy is a secondary concern, but understanding its limitations is still critical for potential buyers.

City and highway performance

The EPA estimates of 15 MPG in the city and 20 MPG on the highway accurately reflect what owners see. The city figure takes a hit because of the engine’s displacement and the vehicle’s significant weight, requiring more fuel to get it moving from a standstill. The highway number is slightly better, because of the 10-speed automatic transmission, which allows the engine to cruise at lower RPMs. Still, aerodynamic drag at highway speeds means you’ll be visiting the gas station more often than you might like.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,400 for this specific Yukon configuration. This calculation is based on driving 15,000 miles per year, with 55% of the miles driven in the city and 45% on the highway, using national average fuel prices. Remember that regional gasoline prices can fluctuate significantly, which will cause your actual fuel costs to differ from this estimate. Your personal driving habits will heavily influence the final bill. Aggressive acceleration and frequent stop-and-go traffic will quickly inflate that $3,400 figure.

Real-world expectations

The EPA provides a standardized benchmark, but reports suggest that achieving the advertised numbers can be difficult. Drivers who frequently tow or carry heavy loads will likely see even lower MPG figures. However, those who spend a significant portion of their time on open highways, driving conservatively, might be able to nudge the numbers slightly upwards, though exceeding 20 MPG on a consistent basis will be difficult. Also look at YUKON MPG across all years to see if there’s a better fit based on your needs.

How it compares

The Yukon’s fuel economy puts it in line with its direct competitors. The 2021 Chevrolet Tahoe 2WD with the 5.3-liter V8 (not even the larger 6.2L) achieves a combined 18 MPG. Other large SUVs, such as the Ford Expedition, offer similar figures in the 17-20 MPG range depending on configuration. The difference comes down to tenths of a mile per gallon, a largely insignificant amount when the overall consumption is already so high. For many Yukon buyers, the powerful 6.2-liter V8 and its 420 horsepower outweigh the fuel economy penalty. They prioritize capability and performance over saving a few dollars at the pump. Buyers interested in all Gmc fuel economy data might want to explore other options should fuel efficiency be very important.

Tips to maximize efficiency

Despite its inherent thirst, there are steps you can take to improve the Yukon’s fuel economy. Gentle acceleration is key. Avoid stomping on the gas pedal, especially from a standstill, as this dramatically increases fuel consumption. Let the 6.2-liter V8’s ample torque do the work without excessive throttle input.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, which forces the engine to work harder and burn more fuel. Consult the sticker on your driver’s side door jamb for the recommended tire pressure and make sure your tires are properly inflated.

Minimize excessive idling. Idling consumes fuel without covering any distance. If you anticipate being stopped for more than a minute or two, turn off the engine. Modern vehicles are designed to restart quickly and efficiently, so there’s no need to let the engine run needlessly.

When possible, anticipate traffic flow to avoid unnecessary braking and acceleration. Maintaining a steady speed improves fuel economy. Using cruise control on the highway can help you maintain a consistent speed and reduce the temptation to speed up and slow down unnecessarily.

Consider the weight of your cargo and reduce unnecessary loads. Extra weight requires more energy to move, which translates to lower fuel economy. Remove any items you don’t need from the vehicle, especially heavy objects, to lighten the load and improve efficiency.
