What is the gas mileage of a military Humvee?

The gas mileage of a military Humvee varies depending on several factors, including the specific model, engine, terrain, and driving conditions. Generally, the M998 Humvee, powered by a 6.2L diesel engine, has a fuel consumption of around 6 to 8 miles per gallon (mpg) in urban driving conditions and 10 to 15 mpg on the highway.

Due to their heavy weight and large engines, Humvees are known for their relatively low fuel efficiency compared to standard passenger vehicles. Additionally, factors such as added armor, equipment, and extreme off-road usage can further reduce fuel economy. To mitigate this, some modern Humvee variants utilize improved engineering, hybrid configurations, and alternative fuel options to enhance fuel efficiency during missions.
