How Much Higher is the Fuel Consumption of AWD Compared to 2WD?

[LeVictoria]

For the same brand and model, the AWD version typically consumes 0.5-1 liter more fuel per 100 kilometers than the 2WD version. However, in terms of maintenance costs, AWD models are more expensive due to additional components such as differentials and rear axles. 1. Reasons: Engine displacement is generally higher than that of sedans in the same class, and larger displacement naturally requires more fuel consumption; the taller and bulkier body leads to higher aerodynamic drag, which is another factor affecting fuel economy. AWD models are usually taller and bulkier, resulting in greater aerodynamic drag compared to streamlined sedans, thus increasing fuel consumption. 2. Factors influencing vehicle fuel consumption: Air conditioning cooling, electrical load; driving conditions; vehicle weight and condition, engine oil performance, tire pressure, tire resistance; driving habits, braking habits; engine temperature (optimal around 70 degrees Celsius—too low, and the oil viscosity increases, reducing lubrication; too high, and the oil's adhesion decreases, reducing lubrication, while the cooling fan activates, consuming electricity and thus fuel); body design (aerodynamics).
