16 MPG combined. That’s the reality when you choose the 2024 Chevrolet Suburban 4WD with its 6.2L V8. It’s a number that won’t win any awards for lower fuel costs, but it’s a number that many Suburban buyers are willing to accept as the cost for ultimate passenger and and cargo hauling capability. These aren’t the people agonizing over a few extra dollars at the pump; they’re the ones who need to transport large families, tow substantial trailers, and do it all with the confidence only a body-on-frame SUV can give. This is the vehicle of choice for large families, those who regularly tow boats or campers, or anyone who prioritizes space and power over fuel efficiency.

City and highway performance

The EPA estimates the 2024 Chevrolet Suburban 4WD 6.2L V8 achieves 14 MPG in the city and 18 MPG on the highway. The city figure reflects the engine’s thirst when navigating stop-and-go traffic, where the weight of the vehicle and frequent acceleration take their toll. The highway figure shows a modest improvement, likely because of the 10-speed automatic transmission’s ability to settle into higher gears and keep the engine at lower RPMs. However, even on the highway, the Suburban is battling significant aerodynamic drag, limiting its fuel-sipping potential.

Annual fuel cost

Owning a 2024 Chevrolet Suburban 4WD 6.2L V8 means considering the sticker price when budgeting. The EPA estimates an annual fuel cost of $3,600 per year, based on 15,000 miles of driving and national average fuel prices. This figure is a reminder of the ongoing expense of operating a large, powerful SUV. It’s a significant cost, and potential buyers should factor this into their budget alongside insurance, maintenance, and other ownership expenses. Anyone considering the SUBURBAN MPG across all years knows fuel economy isn’t its forte.

Real-world expectations

EPA estimates are a useful starting point. However, real-world fuel economy often differs, depending on driving habits, traffic conditions, and cargo load. Expect the 14 MPG city figure to be fairly consistent, perhaps even lower if you encounter particularly congested conditions. The 18 MPG highway figure is more attainable, especially on long, relatively flat stretches of road at consistent speeds. However, towing a trailer will significantly reduce your fuel economy, potentially dropping it into the single digits. Aggressive driving, with frequent hard acceleration, will also have a negative impact.

How it compares

The 2024 Chevrolet Suburban 4WD 6.2L V8 is near the bottom of the fuel efficiency barrel, compared to its rivals. A Ford Expedition 4×4 with the High-Output 3.5L EcoBoost engine, for instance, manages around 17 MPG combined. A Toyota Sequoia 4×4, with its hybrid powertrain, achieves around 20 MPG combined. For a buyer prioritizing fuel economy, these alternatives offer savings. Other models may not offer the exact combination of interior space, towing capacity, or raw V8 power that Suburban buyers often seek. Buyers will also want to research all Chevrolet fuel economy data to know what to expect.

Tips to maximize efficiency

You can’t magically transform your Suburban into a fuel sipper, however, there are steps you can take to improve its efficiency. Avoid aggressive acceleration and braking. The 6.2L V8 loves to roar, but every press of the gas pedal means wasted fuel. Drive smoothly and anticipate traffic flow to minimize unnecessary speed changes.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended level.

Minimize idling. Letting the engine idle for extended periods consumes fuel without moving the vehicle. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, making this a simple way to save fuel.

Reduce your cargo weight. The heavier your vehicle, the more fuel it consumes. Remove any unnecessary items from the cargo area to lighten the load. This is especially important if you regularly carry heavy items that you don’t need on every trip.

Consider using cruise control on the highway. Maintaining a consistent speed optimizes fuel economy. Cruise control can help you avoid unintentional speed fluctuations, potentially saving you fuel on long drives. However, avoid using cruise control in hilly terrain, as it can sometimes lead to inefficient gear changes.
