How many miles per gallon does a 2024 Chevy 2500HD get?

The fuel economy of the 2024 Chevy Silverado 2500HD varies by engine and drivetrain. In general, expect roughly 11–14 mpg combined with the gasoline 6.6L V8 and about 16–19 mpg combined with the 6.6L Duramax turbo-diesel. Exact figures depend on configuration, payload, towing, tires, and drive type.


Engine options and EPA expectations


The Silverado 2500HD can be equipped with two main powertrains. The gasoline engine is comparatively thirsty, while the diesel offers better highway efficiency and sustained torque for towing. The following ranges reflect typical EPA-style estimates and can shift based on drivetrain and equipment. Keep in mind that 4x4, heavier payloads, and larger tires reduce fuel economy.


Gasoline 6.6L V8


Estimated ranges by drivetrain are:



  • 2WD: approximately 11–14 mpg combined (roughly 10–12 mpg city and 14–17 mpg highway).

  • 4x4: approximately 11–13 mpg combined (roughly 9–11 mpg city and 14–16 mpg highway).


Note: Towing, payload, and tire size can push these numbers lower.


Duramax 6.6L Turbo-Diesel


Estimated ranges by drivetrain are:



  • 2WD: approximately 15–19 mpg combined (roughly 11–13 mpg city and 18–23 mpg highway).

  • 4x4: approximately 14–18 mpg combined (roughly 11–13 mpg city and 17–21 mpg highway).


Note: Diesel efficiency tends to improve on highway driving, while towing and payload reduce it.


Real-world factors that influence fuel economy


Beyond engine choice, several factors affect actual MPG in daily use. Heavy payloads, frequent towing, terrain, and driving style all play significant roles. Tyre size, axle ratio, and transmission programming also matter, particularly for a heavy-duty pickup designed for work rather than city commuting.



  • Payload and towing weight

  • Drivetrain configuration (2WD vs. 4x4)

  • Axle ratio and GVWR

  • Tire width and type

  • Driving conditions (city vs. highway, hills, wind)


For the most reliable estimate, check the exact EPA window sticker for your specific build or use the EPA’s fuel economy database for the truck’s year, trim, and options. Real-world results may differ from the ratings.


How to find the exact MPG for your build


To determine the precise miles-per-gallon for a given 2024 Silverado 2500HD configuration, consult the EPA window sticker or the official EPA fuel economy website using your planned drivetrain, engine, axle ratio, tire size, and body style. Dealers can also provide the specific numbers for a built-to-order vehicle.


Summary


The 2024 Chevy Silverado 2500HD offers two engines with distinct efficiency profiles: the gasoline 6.6L V8 typically yields lower mpg (roughly 11–14 mpg combined, depending on configuration), while the Duramax 6.6L turbo-diesel improves highway efficiency (roughly 16–19 mpg combined, with similar caveats about payload and towing). Exact numbers depend on drivetrain, gearing, tires, and how the truck is used. Always verify the EPA ratings for your exact configuration and consider real-world factors such as towing and payload when estimating fuel costs.
