Self Study Program 363 – Audi Q7 – Power Transmission Transfer Case 0AQ

VAG SSP 363. This SSP deals mainly with the design and function of this new development. Audi Q7 – Power transmission by the inventor of the quattro. The powertrain concept of the Audi Q7 offers impressive performance at high speeds in addition to outstanding dynamics, both on and off the road.

The permanent quattro four-wheel drive with asymmetric, dynamic torque split ensures maximum traction and cornering stability. These features are essential to good driving dynamics and active motoring safety, particularly when driving on paved roads and at high speeds.

The newly developed transfer case 0AQ is the centrepiece of the power transmission system.
