Audi Q7 Power Transmission Manual

In addition to outstanding dynamics, the Audi Q7 powertrain concept ensures an impressive performance at high speeds, both on highway and off-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 driving safety. The newly designed 0AQ Transfer Case is a key feature of the power transmission system. The purpose of this SSP is to explain the design and function of this new system. As an SUV with excellent on- and off-road driving dynamics, the Audi Q7 comes standard with the quattro four-wheel drive. As a result, the transmission gear and the transfer case are close to the center of the vehicle, promoting a wellbalanced axle load distribution beneficial to the driving dynamics. The transmission, front axle differential and transfer case are a modular design. The advantage of this modular design is an increased ground clearance for off-road driving.

The self-locking center differential, already in use in the Audi RS4 and S4, features asymmetric-dynamic torque distribution. Up to 85% of drive torque can be transferred mechanically, without EDL engagement, to the rear axle and up to 65% can be transferred to the front axle. When a wheel is spinning - off road or on icy surfaces - the EDL system is activated and helps ensure traction in almost any driving situation. When equipped with the 4.2L V8 FSI engine, the Audi Q7 will use the 09D 6-Speed Automatic Transmission. When equipped with the 3.6L V6 FSI engine, the Audi Q7 will use the 0AT 6-Speed Automatic Transmission.

The left drive shaft is extended to compensate for the front axle differential asymmetric mounting. The additional torque resulting from the drive torque is, therefore, transmitted symmetrically to the front axle. This eliminates any negative effect on steering. The 0AQ Transfer Case has been redesigned for use in the Audi Q7. The 0AQ Transfer Case was developed in collaboration with Borg-Warner. It is manufactured by Borg-Warner. The 0AT 6-Speed Automatic Transmission is an electrohydraulically controlled 6-speed planetary transmission (multi-step automatic transmission) with hydrodynamic torque converter and slip-controlled converter lockup clutch. The valve body and the electronic control module have been combined into a single unit, called the Mechatronics, located inside the oil sump. This transmission will be introduced during the third or fourth quarter of 2006. This transmission will be used on vehicles equipped with the 3.6L V6 Engine.
