While 17 MPG combined won’t impress anyone, the 2020 Chevrolet Suburban C1500 2WD with the 6.2L V8 is designed for hauling families, towing boats, and carrying lots of cargo. The V8 offers capability that its target buyer prioritizes over saving money on gas. This Suburban appeals to those with specific needs, and compromise isn’t an option.

City and highway performance

The EPA estimates 14 MPG in the city and 23 MPG on the highway, highlighting the difference between stop-and-go driving and consistent speed cruising. The 6.2L V8 works well on open roads, where its torque allows it to maintain speed with minimal effort. The 10-speed automatic transmission plays a critical role, keeping the engine in its most efficient range. In the city, the Suburban’s weight (over 5,500 pounds) and the engine’s displacement become liabilities. Frequent acceleration and deceleration use fuel quickly, making city driving expensive.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Chevrolet Suburban C1500 2WD 6.2L to be $3,400. This is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. This assumes national average fuel prices. This is just an estimate, and individual costs will vary based on driving habits and local fuel prices. However, it provides a benchmark for prospective buyers to understand the potential ongoing expense of owning this large SUV.

Real-world expectations

The EPA figures offer a reference point, but real-world fuel economy can vary based on several factors. Aggressive driving, heavy towing, and running larger aftermarket tires will all decrease fuel economy noticeably. Drivers who prioritize smooth acceleration and maintain consistent speeds on the highway may see results closer to, or even slightly exceeding, the EPA estimates of all Chevrolet fuel economy data. The SUBURBAN MPG across all years is widely available for comparison.

How it compares

Competitors like the Ford Expedition offer slightly better fuel economy. The Expedition’s EcoBoost V6 can achieve around 17 MPG city and 23 MPG highway in 2WD form, thanks to its turbocharged engine. However, the Suburban buyer often prefers the smooth power delivery and familiar character of a naturally aspirated V8. Even other GM products such as the GMC Yukon Denali with the same 6.2L engine offer comparable numbers, although minor variations in curb weight and aerodynamics can shift the numbers slightly. Buyers considering a Cadillac Escalade, which shares a platform and engine options with the Suburban, will find it delivers similar fuel economy figures. The key takeaway: fuel economy is rarely the primary deciding factor in this segment. Capability, size, and brand loyalty often outweigh the small differences in gas mileage.

Tips to maximize efficiency

Anticipate traffic flow. The Suburban’s size and weight require more energy to accelerate and decelerate. Look ahead, and coast when possible. Every unnecessary burst of throttle burns fuel, so smooth and steady driving helps efficiency in this vehicle.

Avoid extended idling. The 6.2L V8 consumes fuel even when stationary. If you anticipate being stopped for more than a minute or two, turn off the engine. Restarting uses less fuel than prolonged idling. This simple habit can save gallons over the course of a year.

Use cruise control on the highway. Engaging cruise control allows the vehicle to maintain a consistent speed, reducing unnecessary acceleration and deceleration. This helps on longer trips. Even moderate speed variations contribute to lower fuel economy.

Ensure proper tire inflation. 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 manufacturer’s recommended level, found on the doorjamb sticker.
