Volkswagen's 4WD system works and its functional benefits are as follows: Principle of Volkswagen's 4WD system: It utilizes the unidirectional transmission characteristic of worm gears (motion can only be transmitted from the worm to the worm wheel, otherwise self-locking occurs), thus enabling more timely and reliable adjustment of front-rear torque distribution compared to electronically hydraulically controlled central differential systems. Advantages of Volkswagen's 4WD system: It is suitable for models with front transverse engine front-wheel drive platforms, which makes it possible for many SUVs or 4WD sedans built on this platform to be equipped with a 4WD system. The front-wheel drive platform is more conducive to expanding interior space, has higher transmission efficiency, and produces less noise in the transmission system compared to rear-wheel drive platforms.
Volkswagen's 4MOTION all-wheel-drive system uses Haldex coupling technology, with sensors constantly monitoring wheel slip. The moment a wheel loses traction, the computer swiftly redirects power to the wheels with grip. This ensures exceptional stability—no tire slip in rain or snow, and no loss of control during cornering. The benefits are outstanding safety, especially reassuring in winter; off-road capability that feels effortless; and crisp, responsive acceleration for a thrilling drive. Driving a Volkswagen SUV on slippery mountain roads is stress-free, with confident braking and deceleration, while daily city commuting feels more secure. Maintenance is straightforward—just follow the manual—and the system is reliable and durable, making it a worry-free choice for long-term ownership.
