17 MPG combined. That’s what owners of the 2022 GMC Sierra 1500 get when it’s equipped with mud-terrain tires and four-wheel drive, paired with the surprisingly potent 2.7-liter turbocharged four-cylinder engine. This configuration prioritizes off-road capability and rugged looks over ultimate fuel efficiency, and the Sierra buyer opting for this setup knows what they’re getting into.

City and highway performance

The EPA estimates that in city driving, the 2022 GMC Sierra 2.7L 4WD with mud-terrain tires will achieve around 16 MPG. Stop-and-go traffic and the added rolling resistance of those aggressive tires significantly impact fuel consumption. On the highway, the figure improves slightly to 18 MPG. This is a modest increase, the engine cruises efficiently at steady speeds, even with the aerodynamic disadvantage and the truck’s weight.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for this specific configuration of the Sierra is $2,600. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary depending on your individual driving habits, the amount of city or highway driving you do, and where you live, since gasoline prices fluctuate regionally. But $2,600 provides a benchmark against which you can estimate your personal spending.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy can differ. Drivers who frequently engage the four-wheel-drive system, tow trailers, carry heavy loads, or drive aggressively will likely see MPG figures below the EPA estimates. However, those who primarily use the truck for commuting on relatively flat terrain and practice conservative driving habits may be able to achieve slightly better numbers. Mud-terrain tires are designed for grip, not efficiency, and that shapes the vehicle’s economy.

How it compares

The 2022 Ford F-150, when equipped with its base 3.3L V6 and four-wheel drive, manages a slightly better 21 MPG combined. Even the Toyota Tundra, packing a 3.5L twin-turbo V6 in its 4×4 configuration, posts 20 MPG combined. The Chevrolet Silverado 1500, mechanically similar to the Sierra and also offering a 2.7L turbo, achieves identical fuel economy figures in its 4WD configuration with standard tires. These comparisons highlight that the Sierra’s fuel economy, especially with mud-terrain tires, isn’t class-leading. However, the person buying this specific Sierra configuration isn’t prioritizing saving a few dollars. They want the look and capability that comes with the more aggressive tires, and they are willing to trade some fuel efficiency to get it. For all Gmc fuel economy data, you can browse our site.

Tips to maximize efficiency

Even with a vehicle geared towards off-road prowess, there are ways to improve fuel economy. Tire pressure is critical. Ensure your mud-terrain tires are inflated to the pressure listed on the door jamb sticker. Underinflated tires increase rolling resistance and reduce fuel efficiency significantly.

Minimize idling time. Modern engines don’t need extended warm-up periods. Excessive idling wastes fuel, especially in colder weather. If you’re going to be stopped for more than a minute, it’s best to turn off the engine.

Drive smoothly. Avoid aggressive acceleration and braking, which consume more fuel. Gentle, progressive acceleration and anticipating traffic conditions to minimize braking can yield surprisingly positive results over time. The 8-speed automatic is usually very good about being in the right gear, but be mindful of your throttle inputs.

Consider your cargo and towing needs. The less weight you carry, the better your fuel economy will be. Remove unnecessary items from the truck bed, and if you’re not actively towing, remove the trailer hitch to reduce aerodynamic drag. Understanding SIERRA MPG across all years can give insights into how different factors affect overall economy.

Finally, consider a less aggressive tire when it’s time for replacement, if pure off-road capability is not critical. Moving to an all-terrain tire with a less aggressive tread pattern can provide a noticeable improvement in fuel economy without drastically sacrificing off-road performance. This compromise offers both style and efficiency.
