What is the gas mileage on a 2024 Chevy Silverado 2500hd?
The gasoline-powered 2024 Silverado 2500HD typically delivers fuel economy in the low-teens for combined driving, with significant variation based on configuration. In practical terms, expect roughly 11–13 mpg combined, with city mileage around 9–12 mpg and highway mileage in the 12–15 mpg range depending on drivetrain and setup. The diesel version offers better highway efficiency, but this article focuses on the gas option.
How the mileage figures are determined
Fuel economy for heavy-duty pickups like the Silverado 2500HD is influenced by many factors beyond the engine itself. Official ratings come from the EPA and reflect typical driving patterns, but real-world numbers can differ based on payload, towing, terrain, climate, and how the vehicle is equipped.
Engine and transmission options
The Silverado 2500HD’s gasoline option is built around a large V8 engine paired with a heavy-duty automatic transmission. Power, torque, and gearing all affect how efficiently the truck can move weight, especially under load. Different transmissions or gearing can shift the mpg profile, particularly in city driving or when towing.
Drivetrain, cab/bed, and axle choices
Two-wheel drive versus four-wheel drive, crew cab versus regular cab, bed length, and axle ratio all influence aerodynamics, weight, and gearing. These configuration decisions can swing fuel economy by several tenths of a mile per gallon in either direction, especially under load or at highway speeds.
EPA estimates versus real-world experience
Official EPA estimates for the 2024 Silverado 2500HD with the gas engine provide a baseline, but real-world mileage depends on how the truck is equipped and used. The following ranges summarize what owners typically see across common configurations:
- Gasoline engine, 2WD: approximately 9–12 mpg in the city, 12–15 mpg on the highway, with a combined rating around 11–13 mpg.
- Gasoline engine, 4WD: approximately 9–11 mpg in the city, 12–14 mpg on the highway, with a combined rating around 11–12 mpg.
Note: These figures are approximate and vary by cab style, bed length, axle ratio, tire size, payload, and whether the truck is carrying a heavy load or towing. For your exact build, consult the EPA’s Fuel Economy site or the window sticker for precise numbers.
How to maximize gas mileage on a Silverado 2500HD
Even within the same configuration, drivers can influence mpg by adopting mindful driving and maintenance habits. Consider the following practices to help get the best possible fuel efficiency from a gasoline Silverado 2500HD:
- Limit payload and use the truck within its rated tow and payload capacities to avoid excessive strain.
- Maintain proper tire inflation and choose tires that minimize rolling resistance where possible.
- Drive smoothly: steady speeds, moderate acceleration, and anticipating stops can reduce fuel use.
- Keep the vehicle well-maintained with timely oil changes, air filter replacements, and a clean exhaust system.
- Avoid prolonged idling and unnecessary aerodynamic drag, such as roof racks or heavy cargo on the bed when not needed.
These practices can help close the gap between theoretical EPA ratings and what you actually experience in daily driving.
Summary
The 2024 Silverado 2500HD with a gasoline engine is not designed for high fuel economy, but it delivers workable efficiency for a heavy-duty pickup. Expect roughly 11–13 mpg combined on typical 2WD configurations and slightly less with 4WD, with highway numbers generally higher than city numbers. For the most accurate figure, check the EPA ratings for your specific cab/bed/axle arrangement and whether you tow or carry heavy loads. The diesel variant, while more efficient on the highway and for towing, is outside the scope of this gas-focused overview.
