20 MPG combined is a number to consider for the 2022 GMC Sierra 2WD equipped with the 2.7L turbocharged four-cylinder engine. It’s justifiable for the Sierra buyer who prioritizes capability and value over ultimate efficiency and mostly drives in the city. This truck serves a specific purpose, catering to owners who need a workhorse during the week but also use it for personal transportation and weekend projects. The 2.7L engine offers a blend of power and efficiency in a full-size truck, and its availability exclusively in 2WD trims signals the target demographic.

City and highway performance

The EPA estimates for city and highway driving are close, at 19 MPG in the city and 22 MPG on the highway. This tight spread reveals that the Sierra’s 2.7L turbo engine and 8-speed automatic transmission are optimized for consistent performance across mixed driving conditions. The city figure reflects stop-and-go traffic, but the ample torque of the four-cylinder allows it to move the Sierra easily with minimal fuel consumption. The highway MPG is a bit disappointing, suggesting that even with its efficient transmission, the Sierra’s aerodynamics and weight reduce its ability to truly maximize fuel efficiency. Drivers who primarily drive on the highway may want to consider other engine options.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 GMC Sierra 2WD 2.7L to be $2,200. This figure is based on driving 15,000 miles per year and using national average fuel prices, which fluctuate and may be higher or lower depending on your location and driving habits. To get the best estimate for your specific circumstances, drivers can enter their own mileage and fuel costs at fueleconomy.gov. That $2,200 gives buyers a solid benchmark and helps contextualize the financial impact of owning a full-size pickup.

Real-world expectations

While the EPA provides a standardized test, real-world MPG often varies. The Sierra’s 2.7L turbo engine is sensitive to driving style. Aggressive acceleration and frequent towing will significantly decrease fuel economy, potentially dipping below 17 MPG in combined driving. However, a careful driver with a light foot and mostly highway miles could realistically achieve close to 24 MPG on longer trips. Load also plays a factor. Hauling heavy cargo in the bed or towing a trailer will strain the engine and reduce efficiency. The 2.7L is working hard to perform the job of a typically larger engine so be aware of its capabilities and stress levels while using it.

How it compares

Compared to other full-size trucks, the 2022 GMC Sierra 2WD 2.7L is unique. The 2WD Ford F-150 with the 2.7L EcoBoost V6 achieves a better 22 MPG combined. The Sierra’s four-cylinder is a more affordable entry point. Stepping up to the Sierra’s 5.3L V8 drops the fuel economy to around 17 MPG combined, making the 2.7L an appealing compromise for those seeking the utility of a full-size truck without the fuel consumption of a V8. The Chevrolet Silverado 2WD with the same 2.7L engine posts identical EPA numbers, indicating shared powertrain tuning and efficiency. Anyone considering this Sierra should also check SIERRA MPG across all years to ensure complete confidence in their final choices for features and styling when comparing models from different model years. For a broader view, exploring all Gmc fuel economy data offers crucial context.

Tips to maximize efficiency

Minimize idling. The 2.7L turbo engine burns fuel even when stationary. If you anticipate being stopped for more than a minute, turn off the engine to save fuel. Be especially mindful and ready during school pick-up and drop-off times.

Drive smoothly and avoid aggressive acceleration. The Sierra’s turbo engine responds well to gentle acceleration. Gradual starts and maintaining a steady speed will significantly improve fuel economy. Anticipate traffic flow and avoid sudden braking, which wastes energy and fuel.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, reducing fuel efficiency. Check your tire pressure regularly and inflate them to the manufacturer’s recommended levels, typically found on a sticker inside the driver’s side doorjamb. Regular tire rotations are recommended as well.

Reduce weight and aerodynamic drag. Remove unnecessary items from the bed of the truck to minimize weight. If you have a bed cover, ensure it is properly secured to reduce aerodynamic drag at highway speeds. Doing so will keep the truck from working harder than it needs to in order to maintain speed and stability.

Use cruise control on the highway. When appropriate, engage cruise control to maintain a constant speed. This helps prevent fluctuations in throttle input, which can negatively impact fuel economy. Be aware of varying inclines, declines, and wind when using cruise control.
