4MOTION Keeps you safely on

4MOTION gives you great on the road, come rain, or snow. So, however treacherous the surface, you get a sure-footed car with levels of traction.

Our four-wheel systems work hard to you safe, linking with active safety systems on Volkswagen to constantly monitor conditions. It reacts to even the wheel slip and automatically the right amount of power to the with the most grip. The it detects a problem, it delivers traction where it’s

As a driver, you get reassuring stability and control. And the confidence that Volkswagen can safely tackle the roads and the worst weather That lets you relax and your drive, knowing 4MOTION is always on the alert to you safe and help you out of tricky It will take snow and slippery roads and muddy in its stride, and help you get out of places a normal car would be stuck.

Split-second action.

All this in milliseconds, through control that are linked to the car’s sensors, engine management and gearbox. At the heart of the four-wheel system is an inter-axle differential design varies depending on the system. The differential’s job is to share between the front and rear sending it where it’s needed. If the system senses a of traction — caused, for by the wheels on one axle spinning on a surface — it will the wheels’ turning power as — almost instantly to correct the problem.

At the same the smaller differences in rotational that happen when or manoeuvring, have to be balanced to torsional stresses in the drive And the differential must be able to with the car’s other safety systems such as Braking System (ABS) and the stability programme (ESP). In to meet all these different we offer our four-wheel drive in three differential variants. are called:

Haldex clutch

Lockable centre

The Haldex clutch

The Haldex automatically gathers information on the actions, engine performance, and brakes, so it can control the transfer of That lets it deal with all potentially dangerous or driving conditions.

Whether you maximum torque shift in situations or when accelerating or less when taking corners or parking — the keeps you safe while better performance and driving

It distributes power between and rear axles by means of an controlled multi-plate clutch, set the front and rear axles. detect slip between the and rear wheels and apply to the back pair if the powered wheels are spinning, until the two are moving at the same speed. pumps regulate the pressure on the plates and as it rises, the plate are pressed against each Power transmission can be precisely In extreme situations, it’s possible to send almost of power to the rear.

The general of the Haldex clutch is to always the driving forces to the axle the better traction. In this 4MOTION is able to respond and optimally to any driving situation. you still keep the feel of a drive car most of the time. In driving conditions, 90 per cent of the power is sent to the front with 10 per cent going to the This results in improved efficiency, compared with four-wheel drive. And there’s no of torsional stresses on the drive during parking and manoeuvring. The clutch can be linked with all our safety systems, including ABS and

The Torsen differential

The Torsen is a mechanical self-locking centre which regulates power the front and rear axles, torque sensing. It responds to rotational forces between the and rear axle, sending between them as needed. On a differential the two output gears are by worm gears. They high differential rotation but still balance the speeds cornering.

On the Phaeton, under conditions, the Torsen differential driving forces equally front and rear axles. If it wheel slip, it instantly as much as 20 per cent of the driving to the axle with the better (max. 70:30, or 30:70). Its effect increases automatically with the load. In contrast to a sensing viscous lock, it in torque sensing mode. The is the lack of torsional stress cornering, as it is designed to allow the rotational speeds the car automatically to use.

Lockable centre differential on the

The advanced 4xMOTION permanent drive system on the Touareg underpins its impressive off-road Linked to a lockable centre with a multi-plate clutch and gear, it can transmit 100% of to either axle, giving wheels the maximum amount of when you need it. In normal torque distribution between the and rear axles is smoothly as a function of the amount of slip. The differential can also be locked to a fixed drive torque Power is sent to the front by way of a bevel gear.

Volkswagen 4Motion

4MOTION can be ordered with a rear-axle that gives a 100 per cent effect between the rear The locks are activated by the driver, a rotary switch in the Touareg’s When this is used, the forces are no longer diverted via instead, each of the rear transmits the same drive and turns at the same speed as the wheel. This gives you traction in extreme conditions.

If you’re planning some off-road driving, you can select the ratio (2.66:1) electrically by the suspension control switch. delivers maximum traction at low so the Touareg can safely tackle steep slopes.

Electronically controlled 4MOTION is an on the Tiguan*. The off-road drive offers all-terrain capability at the of a button. This instantly on a group of advanced off-road which work together to you safer control over ground.

The hill descent lets you drive down slopes safely by actively all 4 wheels using the ESP hydraulics

The Differential Lock is adjusted to slip earlier

The ABS is adjusted to give better on loose ground

Gear gives optimum engine (on automatic gearboxes)

The accelerator is adjusted for finer control of in low gears

The parking brake helps to reduce clutch in hill starts
