The core reason why luxury cars generally adopt rear-wheel drive (RWD) lies in their superior handling performance and brand heritage. The rear-wheel drive layout achieves near 50:50 front-to-rear weight distribution, significantly enhancing vehicle dynamics. Particularly during acceleration, the rearward weight transfer increases rear-wheel traction, allowing models like the Mercedes-Benz S-Class and BMW 7 Series to deliver more precise steering feedback and higher cornering limits. From an engineering standpoint, RWD systems require more complex driveline and differential arrangements, with their technical sophistication indirectly boosting premium pricing, aligning with luxury brands' emphasis on mechanical refinement. However, RWD vehicles also exhibit drawbacks including approximately 15% drivetrain energy loss and reduced stability on low-traction surfaces, prompting many premium models to incorporate electronic stability control as compensation. Notably, while electric platforms have redefined weight distribution through battery placement, traditional luxury marques maintain their performance DNA through RWD architecture - as evidenced by electric models like the BMW i4 preserving this design philosophy.
