The ranks of Volvo’s S60 compact luxury cars were recently bolstered by the addition of a new all wheel drive variant called the S60 AWD. The release of an all wheel drive S60 is a significant step by Volvo to ensure its vehicles offer drivers premium levels of safety and vehicle performance. One of the most notable points of the new S60 AWD is that the all wheel drive system is the first electronically controlled system to be fitted to a Volvo car. Previous all wheel drive Volvos used a viscous coupling arrangement. When the front wheels slip, torque is transferred to the rear wheels by the viscous coupling, often causing a certain amount of jerkiness as it locks and unlocks.

The S60’s system is a more sophisticated set-up that uses a ‘Haldex’ clutch to monitor and control wheel slippage. On roads offering good traction, 100 per cent of drive is through the front wheels. However, the set-up reacts instantly to changing road surfaces, varying the proportion of drive to the front and the rear wheels as required.
