20 MPG combined isn’t going to win any economy awards, but it’s a respectable figure for a 2016 GMC Sierra 1500 Hybrid. This isn’t a Prius competitor; it’s a full-size, light-duty pickup with the heart of a workhorse and a bit of efficiency. The Sierra Hybrid targets a specific buyer: someone who needs the capability of a V8 truck but wants to soften the blow at the pump, especially compared to the standard 5.3L Sierra of the same year. This is a truck for light-duty hauling, weekend projects, and occasional towing, not a dedicated long-haul rig.

City and highway performance

The EPA estimates suggest the 2016 Sierra Hybrid achieves 18 MPG in the city and 24 MPG on the highway. The relatively strong highway number reflects the hybrid system’s ability to shut down the gasoline engine under light loads and rely on electric power for cruising. The city MPG, though lower, still benefits from regenerative braking and electric assist during acceleration, improving efficiency in stop-and-go traffic. These numbers are realistically achievable for drivers with a light foot and predictable routines; however, aggressive driving or heavy loads will see them plummet considerably.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 GMC Sierra 1500 Hybrid at $2,200. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Fluctuating fuel prices will directly impact your actual annual spending. The $2,200 figure provides a baseline for comparing the Sierra Hybrid’s operating costs to other trucks and SUVs, but individual expenses could vary greatly.

Real-world expectations

While the EPA provides standardized estimates, real-world fuel economy for the 2016 Sierra Hybrid will depend heavily on driving habits, load, and terrain. Owners reporting their own figures often see results that vary from the official numbers. If you’re frequently towing or hauling heavy cargo, expect fuel economy to decline significantly. Similarly, consistent aggressive acceleration or high-speed cruising will negate the benefits of the hybrid system. The Sierra Hybrid rewards drivers who prioritize smooth, consistent movements and anticipate traffic conditions.

How it compares

Compared to its non-hybrid sibling, the 2016 GMC Sierra 1500 with the standard 5.3L V8 (non-hybrid) achieves about 16 MPG combined. The hybrid provides a noticeable improvement, especially for owners who spend a significant amount of time driving in city conditions. In contrast, a 2016 Ford F-150 with the 2.7L EcoBoost V6 nets around 22 MPG combined, a better figure. The Ram 1500 EcoDiesel, rated at 23 MPG combined for its 2016 model year, also presents a more fuel-efficient option. These differences are crucial for buyers who prioritize fuel economy above all else. See SIERRA MPG across all years.

Tips to maximize efficiency

Gentle acceleration and braking are important. The Sierra Hybrid uses regenerative braking to capture energy during deceleration, so avoid hard stops whenever possible. Anticipate traffic and coast to red lights or slow-moving vehicles, allowing the system to maximize energy recovery.

Maintain a steady speed on the highway. The hybrid system can disengage the gasoline engine under light loads, but only if you’re not constantly accelerating and decelerating. Using cruise control on flat stretches of road can help maintain a consistent pace and improve fuel economy.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which forces the engine to work harder and reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended level found on the sticker inside the driver’s side door.

Reduce unnecessary weight in the truck bed. Hauling around heavy items when you don’t need them decreases fuel economy. Remove any unnecessary tools, equipment, or materials from the bed to lighten the load and improve efficiency.

Consider the driving mode. Some Sierra Hybrid models feature selectable driving modes that prioritize fuel economy. Experiment with these modes to find which one best suits your driving style and conditions. Owners can use all Gmc fuel economy data to compare different models.
