The secrets behind the efficiency of Volkswagen’s 4MOTION system
If you've ever seen the letters 4MOTION on the back or side of a Volkswagen product, you've probably deduced that this name refers to the manufacturer's four-wheel drive system. However, do you know exactly how it works?
Simply put, Volkswagen's 4MOTION system works by sending power to the wheels of the car that have the most grip. Sensors monitor road conditions using a series of parameters and distribute the power to optimize the model's grip. If a wheel starts to spin, on a muddy surface or in snow, for example, the system sends more torque to the wheels that have solid contact with the ground. The 4MOTION system also tries to balance the different speeds of all four wheels of a car in corners.
The 4MOTION’s heart is a central differential that connects the front and rear axles. This system works in parallel with various safety devices such as ABS (anti-lock braking system) and ESP (electronic stability program). Depending on the model, the differential may vary if you look at all Volkswagen products around the world, but generally, it is a Haldex system.
Its multi-plate clutch is there to regulate power and can send everything to the rear wheels. Most four-wheel drive Volkswagens use this system, which is also suitable for performance cars. For example, with a model like the Golf R, it allows quick acceleration and confident cornering even in less than optimal weather conditions. Under normal driving conditions, power is distributed to the front wheels to improve fuel economy.
Above all, taking advantage of a Volkswagen model equipped with 4MOTION all-wheel drive is like taking the wheel of a vehicle that provides an additional safety net in all circumstances.
