Are Four-Wheel Drive Vehicles More Fuel-Consuming?

[JessicaRose]

Four-wheel drive vehicles are indeed more fuel-consuming compared to two-wheel drive vehicles. The characteristic of four-wheel drive vehicles is that they have a large engine pulling a relatively small car, and the engine displacement is generally larger than that of two-wheel drive vehicles, which naturally leads to higher fuel consumption. Reasons for higher fuel consumption: The overall vehicle weight increases, and for four-wheel drive vehicles where the front axle can be disconnected, when the front axle is disengaged, the resistance of the transmission system itself increases the engine's power consumption. Principle of four-wheel drive vehicles: Simply put, a four-wheel drive vehicle is one with front and rear differential-linked four-wheel drive. Because the engine power is transmitted to all four wheels, all four wheels can exert force. In a regular two-wheel drive vehicle, when one of the drive wheels slips, the other drive wheels also lose power, rendering the vehicle immobile. However, if the vehicle is four-wheel drive, the other two wheels can still provide traction. Therefore, four-wheel drive vehicles have superior off-road performance and can handle rough terrain such as hills, beaches, mud, and deserts with ease (though this also depends on the brand and quality of the vehicle). This unstoppable, rugged style has won the hearts of many car enthusiasts.
