2025 Chevrolet Suburban 2WD 6.2L: Fuel Economy Deep Dive

16 MPG combined is the number to understand if you’re considering the 2025 Chevrolet Suburban 2WD with the 6.2L V8. It’s a stark reality, but often secondary for the Suburban’s target demographic: families needing maximum passenger and cargo space, those who tow frequently, and professionals who use the Suburban as a rolling office and equipment hauler. They prioritize capability and size above all else, and the Suburban delivers. This isn’t a vehicle for budget-conscious commuters; it’s a tool for specific tasks, and its fuel consumption is a known cost of doing business.

City and highway performance

The EPA estimates the Suburban 2WD 6.2L at 15 MPG in the city and 19 MPG on the highway. These numbers reflect the engine’s inherent thirst, especially when moving a vehicle that weighs over 5,500 pounds. The 10-speed automatic transmission does its best to keep the engine in its most efficient range, but the sheer power output of that V8 and the temptation to use it, inevitably leads to regular trips to the gas station. Expect the city figure to drop in stop-and-go traffic, while maintaining a steady speed on the open road might get you closer to that 19 MPG highway estimate.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Chevrolet Suburban 2WD 6.2L at $3,600. This figure is based on driving 15,000 miles per year and using national average fuel prices. Individual spending may be higher or lower depending on your specific driving habits and where you live, as fuel costs vary considerably across the country. However, $3,600 provides a standardized benchmark for understanding the financial commitment required to keep this vehicle fueled. For those driving significantly more than 15,000 miles annually, be prepared for a considerably higher fuel bill.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can vary significantly. Aggressive driving, towing, carrying heavy loads, and even tire pressure can all impact your MPG. Drivers who regularly tow will see a substantial drop in fuel economy. Achieving even the EPA estimates will require a conscious effort to drive conservatively. Understand that this is a large, powerful vehicle, and driving it as such exacts a penalty at the pump.

How it compares

Compared to other large SUVs on the market, the Suburban 2WD 6.2L’s fuel economy is generally on par with its direct competitors equipped with similar engines. For instance, a similarly configured Ford Expedition with the high-output EcoBoost V6 achieves roughly the same MPG.

A Toyota Sequoia with its hybrid powertrain offers slightly improved fuel economy, achieving around 22 MPG combined, but sacrifices some of the raw towing capability of the Suburban’s 6.2L V8. The GMC Yukon, mechanically identical to the Suburban, will deliver comparable numbers. Buyers choosing the Suburban with this powerplant aren’t necessarily cross-shopping for maximum efficiency; they are prioritizing power and capability, willing to accept the associated fuel costs.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The 6.2L V8 is responsive, but every hard acceleration burns extra fuel. Anticipate traffic flow and maintain a smooth, consistent speed whenever possible. This will not only improve your MPG but also make for a more comfortable ride.

Ensure your tires are properly inflated. Low tire pressure increases rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the manufacturer’s recommended specifications, usually found on a sticker inside the driver’s side doorjamb.

Minimize idling. Idling wastes fuel, especially in a large-displacement engine like the 6.2L V8. If you’re stopped for more than a minute, consider turning off the engine. Modern starters are designed to handle frequent start-stop cycles.

Keep up with regular maintenance. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug maintenance. A neglected engine works harder and burns more fuel.
