The main reasons why rear-wheel drive (RWD) is more favored than all-wheel drive (AWD) lie in its simple structure, cost advantages, and handling characteristics. RWD models concentrate power delivery to the rear wheels, while the front wheels are dedicated to steering. This division of labor design provides more precise steering response and a higher cornering limit on dry paved roads, making it particularly suitable for performance models that pursue driving pleasure, such as the BMW 3 Series or Cadillac CT5. Their near 50:50 weight distribution (considered the golden ratio) can significantly enhance dynamic stability. Models with the same configuration usually cost 20,000 to 50,000 Ringgit less, with fuel consumption reduced by 0.8 to 1.5 litres per 100 kilometres, resulting in annual fuel cost savings of approximately 2,000 to 3,000 Ringgit, while maintenance costs are also lower due to the simplified structure. The additional 150kg weight of AWD continuously increases fuel consumption, making RWD more practical for cost-effectiveness and driving experience for users who primarily commute in urban areas. Furthermore, with the advancement of electrification, some new energy vehicles have optimized their electronic control systems to balance rear-wheel drive's handling characteristics with four-wheel drive's stability, thereby further expanding RWD's application scenarios.
