20 MPG combined might not sound impressive, but for the 2021 Chevrolet Silverado 4WD equipped with the 2.7L turbocharged 4-cylinder engine, it represents an appealing balance of capability and efficiency. This isn’t for hypermilers; it’s for the contractor, the weekend adventurer, or the suburbanite who needs a truck bed but doesn’t want the fuel bill of a V8.

City and highway performance

The EPA estimates for the 2021 Silverado 2.7L 4WD break down to 19 MPG in the city and 22 MPG on the highway. The city figure reflects stop-and-go traffic and lower speeds, where the engine works harder to move the truck’s weight. The turbocharger provides ample low-end torque, helping the Silverado feel responsive even when loaded. On the highway, the 8-speed automatic transmission helps keep the engine in its best range, allowing decent fuel economy at cruising speeds. The relatively tall gearing minimizes engine RPMs, contributing to reduced fuel consumption over long distances.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2021 Chevrolet Silverado 4WD 2.7L is $2,200. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Actual fuel costs will vary depending on individual driving habits, local fuel prices, and the grade of fuel used. Some Silverado owners may see higher or lower fuel costs depending on how they use their truck, but this provides a benchmark for budgeting.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy can vary significantly. Aggressive driving, towing, hauling heavy loads, and driving in extreme weather conditions can all negatively impact fuel efficiency. Conversely, smooth acceleration, consistent speeds, and proper tire inflation can help drivers achieve or even exceed the EPA estimates. Many owners average closer to the combined figure, especially with mixed driving.

How it compares

The 2021 Silverado’s fuel economy makes it competitive within the full-size truck segment. The 4WD Ford F-150 with the 2.7L EcoBoost V6 is rated at 20 MPG combined, matching the Silverado’s rating. The Ram 1500 with the eTorque V6 manages around 21 MPG combined with 4WD. The V6 Toyota Tundra, while reliable, lags behind with EPA estimates closer to 17 MPG combined. For buyers prioritizing fuel economy without sacrificing truck capabilities, the Silverado 2.7L 4WD offers an alternative to larger engines. Check SILVERADO MPG across all years.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the Silverado 2.7L. The turbocharger provides plenty of power, but heavy-footed driving will diminish fuel efficiency. Respect the accelerator pedal. Especially when starting from a stop, and you’ll see a noticeable improvement.

Proper tire inflation is another simple way to save fuel. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check your tire pressure regularly and inflate them to the recommended pressure listed on the door jamb sticker. This improves fuel economy and extends the life of your tires.

Reduce unnecessary weight in the bed of the truck. Carrying heavy loads for extended periods decreases fuel economy. Only load the truck with what you need, and remove any excess weight when no longer required.

Plan your trips and avoid unnecessary idling. Idling consumes fuel. If you anticipate waiting for more than a minute, turn off the engine to conserve fuel. Combining multiple errands into a single trip can also reduce overall mileage and fuel consumption.
