16 MPG combined isn’t going to win any awards, but it’s the price you pay for the sheer capability that the 2022 Chevrolet Suburban 4WD with the 6.2L V8 offers. We’re talking about a full-size SUV that can comfortably haul a large family, their gear, and tow a substantial trailer , all while delivering the kind of confident performance that only a big, naturally aspirated V8 can provide. This isn’t a vehicle for hypermilers; it’s for those who prioritize space, power, and utility above all else, and who are willing to accept the fuel consumption that comes with it. It’s a tool, pure and simple, and its owners understand that.

City and highway performance

The EPA estimates the 2022 Suburban 4WD 6.2L at 14 MPG in the city and 19 MPG on the highway. The city figure reflects the engine working hard to move this substantial vehicle from stoplight to stoplight, and the impact of idling in traffic. The highway number, while still not stellar, is more achievable because of the 10-speed automatic transmission, which allows the engine to cruise at lower RPMs once up to speed. A lighter foot and careful use of cruise control on the highway can help you approach that 19 MPG figure. However, aggressive acceleration or headwinds will bring the fuel consumption up considerably.

Annual fuel cost

The EPA estimates that the annual fuel cost for this Suburban configuration is $3,600. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also uses the national average fuel price. Naturally, your actual fuel expenses will vary depending on how much you drive and the prevailing fuel prices in your area. If you drive significantly more than 15,000 miles annually, or if gas prices are high in your region, expect to spend considerably more than $3,600 per year on fuel.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy often differs. With the Suburban 6.2L, factors like driving style, terrain, and load significantly impact fuel consumption. Towing, in particular, will drastically reduce MPG, potentially dropping into the single digits if hauling a heavy load uphill. Aggressive drivers, those who frequently accelerate hard, can expect to see figures below the EPA’s city estimate. Someone who drives conservatively on relatively flat terrain may be able to match or slightly exceed the highway estimate. Expectations should be tempered, however. This is a large, powerful vehicle, and its fuel consumption reflects that.

How it compares

Compared to its rivals, the 2022 Suburban 4WD 6.2L’s MPG isn’t a standout. A similarly equipped Ford Expedition with the High-Output 3.5L EcoBoost V6 provides better fuel economy – around 17 MPG combined. The Nissan Armada, with its 5.6L V8, is also in the same ballpark as the Suburban, but typically lags slightly behind. Someone considering a GMC Yukon Denali with the 6.2L V8 will see similar fuel consumption numbers. The Chrysler Pacifica Hybrid, though not a direct competitor in terms of size or towing capability, offers significantly better fuel economy and is often considered by those who don’t require the Suburban’s extreme capabilities.

The comparison is critical. No one buys a Suburban expecting Prius-level efficiency. But for those who need the Suburban’s capabilities, the difference of 1-2 MPG against competitors is a secondary concern behind power, towing capacity, and interior space.

Tips to maximize efficiency

Gentle acceleration is key. Avoid flooring the accelerator, as the 6.2L V8 will readily gulp down fuel when asked to deliver peak power. Anticipate traffic flow and drive smoothly to minimize braking and acceleration. This will reduce unnecessary fuel consumption and improve your overall MPG.

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 pressure level listed on the driver’s side doorjamb. A properly inflated tire will improve gas mileage and handling, and extend tire life.

Reduce unnecessary weight. The heavier the vehicle, the more fuel it consumes. Remove any unnecessary items from the cargo area and passenger compartment. While a few pounds might not seem significant, the cumulative effect can impact fuel efficiency, especially during city driving.

Service your vehicle regularly. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug replacements. A properly tuned engine will deliver the best possible fuel economy.

Consider using a fuel consumption app. These apps allow you to track your fuel economy over time, identify trends, and optimize your driving habits. By monitoring your MPG, you can experiment with different driving techniques and determine what works best for maximizing efficiency in your Suburban.
