What type of engine is typically found in an HMMWV?

The High Mobility Multipurpose Wheeled Vehicle (HMMWV) is commonly equipped with a turbocharged diesel engine. This type of engine is favored for its durability, efficiency, and enhanced torque, which are essential for military operations that require reliability and performance in various terrains and conditions. Diesel engines generally offer better fuel efficiency compared to gasoline engines and have a longer operational range, which is particularly advantageous for the extended missions of military vehicles. The turbocharging feature further improves the engine's power output and performance, enabling the HMMWV to handle heavy loads and difficult off-road situations effectively.

This configuration aligns well with the design goals of the HMMWV to serve as a versatile and reliable platform, meeting the demands of combat and logistical support. Other options, such as gasoline engines or electric motors, do not provide the same level of durability and performance necessary for military applications. Additionally, rotary engines are not commonly used in the HMMWV due to their unique characteristics and operational limitations compared to the traditional diesel engine.
