The fuel economy for a 2001 GMC Sierra varies depending on the engine and configuration. Generally, it averages around 15 to 20 miles per gallon (mpg) for city driving and 20 to 25 mpg on the highway. Specific figures may differ based on the vehicle's condition, maintenance, and driving habits. Always check the owner's manual or manufacturer specifications for the most accurate information.
