The 2020 GMC Yukon C1500 2WD with the 6.2-liter V8 gets 17 MPG combined. This Yukon isn’t purchased by drivers looking to maximize gas mileage, it’s for those who need serious hauling and towing capability in a relatively stylish, comfortable package, and are willing to pay the price at the pump. It’s a tool, albeit a luxurious one, and its thirst is a known quantity for its target demographic.
City and highway performance
The EPA estimates 14 MPG in the city and 23 MPG on the highway. The difference reflects the engine’s Active Fuel Management (cylinder deactivation) system, which shuts down cylinders under light loads, primarily benefiting steady-state highway cruising. In stop-and-go traffic, the big V8 is working harder, negating any fuel-saving technology. Drivers spending most of their time in urban environments should expect figures closer to the lower end. Highway numbers are achievable if driven with a light foot and a focus on maintaining momentum.
Annual fuel cost
The annual fuel cost for the 2020 GMC Yukon C1500 2WD 6.2L is $3,400, according to EPA estimates. This calculation is based on driving 15,000 miles per year, with approximately 55% city and 45% highway driving, using national average fuel prices. This is an estimate, your personal fuel costs will vary depending on your driving habits, local fuel prices, and the specific conditions in which you operate the vehicle.
Real-world expectations
While the EPA provides a standardized benchmark, real-world fuel economy often deviates. Expect to see figures slightly below the combined 17 MPG in mixed driving conditions, particularly if you frequently tow or haul heavy loads. Aggressive acceleration and frequent hard braking will also negatively impact your mileage. Some owners report achieving the EPA highway figure during long road trips, but achieving the stated combined figure consistently will require mindful driving and avoidance of heavy traffic.
How it compares
The Yukon’s fuel economy is typical for its class. The Ford Expedition with its 3.5-liter EcoBoost V6 manages a slightly better 19 MPG combined, which is an advantage for some buyers, but it may not scratch the same itch as a big V8. The Chevrolet Tahoe, mechanically similar to the Yukon but often available at a slightly lower price, offers similar fuel economy. Stepping up to the Cadillac Escalade, with its even more luxurious appointments, doesn’t drastically alter the fuel consumption. For those considering a smaller SUV, All Gmc fuel economy data may paint a more appealing picture.
Tips to maximize efficiency
Be gentle with the throttle. The 6.2-liter V8 is responsive and powerful, but every stab of the accelerator consumes fuel. Smooth, progressive acceleration is key to minimizing fuel consumption, especially from a dead stop. YUKON MPG across all years can be found here.
Take advantage of the 10-speed automatic transmission. This transmission is designed to keep the engine in its most efficient operating range. Avoid aggressive downshifts and allow the transmission to shift smoothly, and progressively. Using cruise control on long highway drives can help maintain a consistent speed, optimizing fuel efficiency.
Keep your tires properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended level, typically found on a sticker inside the driver’s side door.
Minimize idling. Letting the engine idle for extended periods consumes fuel without covering any distance. If you’re waiting for more than a minute or two, turn off the engine. Modern vehicles are designed to handle frequent starts and stops without excessive wear and tear.
