Which feature contributes to the JLTV's fuel efficiency?

The advanced engine technology is a significant factor that contributes to the JLTV's fuel efficiency. This technology typically involves the integration of modern engine designs and systems that optimize fuel combustion, improve power-to-weight ratios, and enhance overall engine performance. Advanced engines may incorporate features such as turbocharging, direct fuel injection, and electronic controls that allow for better management of fuel use under varying driving conditions. By making the engine more efficient, the JLTV can travel further on a given amount of fuel, which is crucial for operational effectiveness in diverse environments.

In contrast, while a lightweight design can indirectly contribute to fuel efficiency by reducing the overall weight that the engine must propel, it is the specifics of the engine technology that have the most direct impact on fuel consumption. A large fuel tank can extend range but does not improve efficiency, and rugged tires, while important for traction and durability, do not significantly influence fuel economy.
