The 2017 Chevrolet Suburban K1500 4WD with the 5.3L V8 gets 18 MPG combined. It’s not intended to win any efficiency awards. Instead, it’s what you should expect if you absolutely require its specific combination of immense passenger space, cargo capacity, and serious towing capability in all weather conditions. This isn’t a vehicle someone buys accidentally; it’s a deliberate choice driven by necessity and the understanding that practicality trumps Prius-like efficiency.

City and highway performance

The EPA estimates the Suburban K1500 4WD at 15 MPG in the city and 22 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, where the Suburban’s size and weight are most detrimental to fuel consumption. Expect frequent trips to the gas station if your daily routine involves a lot of idling and low-speed maneuvering.

The 22 MPG highway rating is more palatable and achievable on longer trips when the engine settles into a more efficient cruising speed. The 6-speed automatic transmission helps in both scenarios, but ultimately it’s the sheer mass that defines the mileage.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Chevrolet Suburban K1500 4WD at $2,450. This figure is based on driving 15,000 miles per year and using the national average fuel prices at the time of calculation. Keep in mind that your actual costs can vary significantly depending on your driving habits, local fuel prices, and the type of fuel you use, though premium fuel is not necessary in this vehicle.

For Suburban owners, this annual fuel cost is often considered a necessary expense for the capabilities it provides, factored in like insurance and maintenance when budgeting for the vehicle.

Real-world expectations

While the EPA provides a standardized estimate, real-world MPG can vary considerably. Aggressive driving, towing, carrying heavy loads, and even tire pressure can all impact fuel economy. Some owners report figures slightly below the EPA estimates, especially in demanding conditions. Others who prioritize smooth acceleration and consistent highway speeds may see numbers closer to, or even slightly exceeding, the EPA’s 22 MPG highway figure.

It’s important to monitor your own fuel consumption to get a realistic picture of what to expect based on your personal driving patterns.

How it compares

The 2017 Chevrolet Suburban lives in a unique space, with few direct competitors offering the same blend of space and capability. The Ford Expedition, with its 3.5L EcoBoost V6, offers slightly better fuel economy figures, rated at 17 MPG city and 23 MPG highway in its 4×4 configuration. The Toyota Sequoia, another full-size SUV contender, lags behind with EPA ratings of 13 MPG city and 17 MPG highway. These differences matter because for buyers sensitive to fuel costs, even a few MPG can translate to hundreds of dollars saved annually. It’s important to see SUBURBAN MPG across all years to view the differences in reported MPG across vehicle generations and trim levels.

For those cross-shopping within the Chevrolet family, the smaller Traverse offers significantly better economy at 18 MPG city / 27 MPG highway, but sacrifices considerable cargo space and towing capacity. Owners should also view all Chevrolet fuel economy data to see the difference among the lineup.

Tips to maximize efficiency

Minimize idling time. The Suburban’s large engine consumes considerable fuel even when stationary. Turn off the engine if you anticipate waiting for more than a minute or two; don’t assume that idling is better.

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

Anticipate traffic and brake smoothly. Avoid sudden acceleration and hard braking, which waste fuel. By anticipating traffic flow and maintaining a consistent speed, you can improve your fuel efficiency significantly.

When towing, use the tow/haul mode. This mode optimizes the transmission’s shift points for towing, preventing excessive gear hunting and improving overall efficiency. It may seem counterintuitive, but it’s engineered to reduce strain on the engine and drivetrain.

Consider removing unnecessary weight. The Suburban is already a heavy vehicle, so removing any unnecessary cargo can improve fuel economy. Clear out any items you don’t need, especially heavy objects that add to the vehicle’s load.
