Since 2008, the four-wheel drive system has been implemented in all Skoda vehicles based
on the Haldex Generation IV coupling . This new generation of the all-wheel drive clutch was incorporated for the first time in the Skoda Octavia II.

The Haldex Generation IV coupling is exclusively electronically controlled, so that each ran-
dom drive torque can build up independently of slip at any time. Thus, the distribution of the drive torque between the front and rear axle is variable and is dependent upon the driving style or the driving situation. The clutch can transfer up to 50% of the drive torque to the rear axle in the event of an extremely high wheel slip at the front axle or due to the current driving situation.

The new generation of the Haldex coupling ensures an optimum transfer of the driving force onto the roadway.
