The main disadvantages of the full-time all-wheel drive (AWD) system include higher purchase costs, reduced fuel economy, and more complex maintenance requirements. Since AWD requires additional transmission components such as a central differential and multiple clutches, its manufacturing cost is usually 5,000 to 15,000 Malaysian Ringgit higher than that of front-wheel drive or rear-wheel drive models, and this cost is directly reflected in the vehicle price. At the same time, the increased weight of the system (about 100-200 kilograms) leads to higher fuel consumption-fuel consumption per 100 kilometres may increase by 1-2 litres in daily use, significantly raising the long-term operating cost. For maintenance, the cost of regular maintenance items for the AWD system, such as differential oil replacement and drive shaft inspection, is 30%-50% higher than that for two-wheel drive models, and technical support from authorised service centers is required. If users mainly drive on paved roads, front-wheel drive vehicles equipped with electronic stability systems can already meet most needs, while AWD is more suitable for drivers who frequently face complex road conditions such as muddy roads and steep slopes.
