16 MPG combined is what you get when you choose the 2023 Chevrolet Suburban 4WD with the 6.2L V8. People choose this Suburban because they need to haul a large family, tow a boat, and handle winter weather, all with a strong V8. This vehicle prioritizes capability and space, and owners understand the fuel consumption trade-off. They’re buying the Suburban for its power and large interior, not for less gas.

City and highway performance

The EPA estimates for the 2023 Chevrolet Suburban 4WD 6.2L V8 are 14 MPG in the city and 18 MPG on the highway. These figures reflect moving a vehicle of this size and weight. The city MPG suffers in stop-and-go traffic, which requires the engine to overcome the Suburban’s inertia. The highway MPG is slightly better, but still reflects the aerodynamic challenges of a large, boxy SUV pushing through the air at higher speeds. The 10-speed automatic transmission optimizes fuel economy, but it’s still fighting against the laws of physics and a thirsty V8 engine.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2023 Chevrolet Suburban 4WD 6.2L V8 is $3,600. This is based on driving 15,000 miles per year and using national average fuel prices. It’s a significant sum, and it’s important to factor into the overall cost of ownership. This is just an estimate, and your actual fuel costs may vary depending on your driving habits, the price of gasoline, and the type of driving you do.

Real-world expectations

EPA estimates provide a good baseline, but real-world fuel economy can vary. If you frequently tow, drive aggressively, or spend a lot of time in stop-and-go traffic, expect lower fuel economy than the EPA estimates. However, if you drive primarily on the highway at consistent speeds and avoid hard acceleration, you may get slightly better fuel economy. Don’t expect miracles. Most owners find the EPA estimates to be a reasonably accurate of what they experience in everyday driving.

How it compares

The 2023 Chevrolet Suburban 4WD 6.2L V8 isn’t winning any fuel economy contests. The Ford Expedition Max with the 3.5L EcoBoost V6, for example, achieves a combined MPG of 17 (4×4 version). Even the standard Chevrolet Suburban with the 5.3L V8 offers slightly better fuel economy at 17 MPG combined for the 4WD version. People wanting maximum power for towing are willing to trade a single MPG for the extra power of the 6.2-liter engine. For those looking for better fuel economy, consider the GMC Yukon Denali with the 3.0-liter Duramax diesel, since it achieves 22 MPG combined with 4WD.

Tips to maximize efficiency

The 2023 Chevrolet Suburban 4WD 6.2L V8 isn’t known for its fuel efficiency, but you can minimize fuel consumption. Avoid aggressive acceleration and braking, as this can impact fuel economy. Gentle and consistent driving will help you get the most out of each gallon of gasoline.

Keep your tires properly inflated. Under-inflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the doorjamb or in the owner’s manual.

Reduce unnecessary weight. The heavier your vehicle, the more fuel it will use. Remove any unnecessary items from the cargo area and avoid carrying heavy loads unless necessary. Even small weight reductions can make a difference in fuel economy.

When towing, use the appropriate tow mode and adjust your driving habits accordingly. Towing reduces fuel economy, so drive smoothly and avoid excessive speed. Consider the diesel engine if towing is a constant part of your ownership experience.
