The 2020 GMC Yukon C1500 XL 2WD with the 6.2L V8 achieves 17 MPG combined, which shows this full-size SUV’s purpose: hauling people and cargo in comfort and style, with performance prioritized over fuel efficiency. This isn’t a vehicle purchased for using little fuel; it’s for buyers who need its ample space and towing capability and accept the fuel consumption as a trade-off.

City and highway performance

The EPA estimates 14 MPG in the city and 23 MPG on the highway. The difference between these figures shows the impact of stop-and-go traffic on a large engine powering a heavy vehicle. The 10-speed automatic transmission helps optimize fuel economy at highway speeds, allowing the engine to cruise at lower RPMs. However, the city mileage reflects frequent acceleration and deceleration, where the engine works harder to move the vehicle.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 GMC Yukon C1500 XL 2WD 6.2L V8 at $3,400. This figure is based on driving 15,000 miles per year and using national average fuel prices. The $3,400 annual fuel cost provides a financial perspective on running this Yukon. Actual fuel costs, of course, depend on driving habits and fuel prices.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy can vary. Aggressive driving, carrying heavy loads, towing trailers, and even ambient temperature can all change fuel consumption, so drivers frequently engaging in these activities should expect to see figures below the EPA estimates. However, drivers who prioritize smooth acceleration, anticipate traffic, and minimize idling might achieve results closer to, or even slightly above, the EPA numbers.

How it compares

Compared to other full-size SUVs, the 2020 GMC Yukon C1500 XL 2WD 6.2L V8’s fuel economy is on the lower end. For example, a 2020 Ford Expedition 2WD with the 3.5L EcoBoost V6 manages around 20 MPG combined. Even the Chevrolet Tahoe with the 5.3L V8 often delivers slightly better fuel economy numbers. For shoppers who might be interested in viewing all Gmc fuel economy data, this is great way to assess the full range of options. The difference is in the Yukon’s larger, more powerful 6.2L engine, which provides stronger acceleration and higher tow ratings, but uses more fuel. Someone cross-shopping might also want to look at YUKON MPG across all years, which can help inform their decision.

Tips to maximize efficiency

Adopt smooth acceleration and braking habits. Avoid abrupt starts and stops, as these consume significantly more fuel. Gently ease onto the accelerator, allowing the 6.2L engine’s ample torque to propel the vehicle forward without too much throttle.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. Check your tire pressure regularly and inflate them to the recommended levels found on the doorjamb sticker.

Minimize idling time. Modern engines consume fuel even when idling. If you anticipate being stopped for more than a minute, turn off the engine. This is especially relevant in city driving with frequent traffic lights.

Consider using cruise control on long highway drives. Cruise control helps maintain a consistent speed, preventing unnecessary acceleration and deceleration. This can improve fuel economy on open roads.

Keep your vehicle properly maintained. Regular oil changes, air filter replacements, and spark plug maintenance ensure the engine runs efficiently. A well-maintained engine consumes less fuel and produces fewer emissions.
