Do 4WD vehicles have higher fuel consumption?

4WD vehicles generally consume more fuel compared to 2WD vehicles. Normal fuel consumption of 4WD vehicles: The fuel consumption varies among different 4WD models. Typically, 4WD vehicles consume around 10L/100km. Methods to reduce fuel consumption: When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed. Sudden acceleration can significantly increase fuel consumption. Gentle acceleration not only shortens the engine warm-up time but also improves fuel efficiency, thus saving fuel. While driving, avoid sudden increases in engine RPM and prevent the vehicle from shaking, which helps in fuel conservation. Maintain tire pressure at the manufacturer-recommended level. For every 2 PSI below the recommended value (approximately 0.2 in metric units relative to the standard pressure of 2.4), fuel consumption increases by 1%. Avoid using winter tires all year round, as this can increase fuel consumption by 10%. Use winter tires only when necessary. Regular maintenance and oil changes can reduce carbon buildup (carbon deposits can cause uneven ignition, sluggish acceleration, increased fuel consumption, and in severe cases, even engine misfire).
Four-wheel drive vehicles generally consume more fuel than two-wheel drive ones, mainly due to the additional drivetrain components that add weight and resistance, requiring the engine to work harder. Having driven many off-road vehicles and SUVs myself, I can say it's normal for four-wheel drive to burn 10-15% more fuel than two-wheel drive in city driving, with a smaller difference on highways. However, the advantages of four-wheel drive are obvious off-road, such as better traction in rain or snow and higher safety, making the higher fuel consumption acceptable. Modern four-wheel drive systems have improved, with some part-time systems activating only when needed and operating like two-wheel drive otherwise, thus reducing fuel consumption. Overall, the choice depends on usage: it's worth it if you frequently drive on muddy roads, but for pure commuting, choosing two-wheel drive can save some fuel costs. Regular maintenance like checking tire pressure and replacing air filters can also optimize fuel efficiency—don't just blame the vehicle.
