In that original quattro system, later found in road-going passenger cars, the engine and transmission are situated in a longitudinal position. Torque is sent through the transmission to a mechanical centre differential [3] (commonly abbreviated to "diff") which apportions (distributes) the torque between front and rear driven axles. 4WD was permanently active.
Torsen differential from an Audi quattro. Torsen Torque-Sensing (full name Torsen traction) is a type of limited-slip differential used in automobiles. It was invented by American Vernon Gleasman [1] and manufactured by the Gleason Corporation. Torsen is a portmanteau of Torque-Sensing.
Allison followed the WT (3000 and 4000 Series) line with the 1000 and 2000 Series starting in 1999. [3] The 1000 Series transmission incorporated many features from the WT line for light-duty trucks, including the electronic control system, and was initially available as an option with the 6.6L GM/Isuzu Duramax diesel engine and the 8.1L Vortec ...
Most torque vectoring differentials are on all-wheel drive vehicles. A basic torque vectoring differential varies torque between the front and rear wheels. This means that, under normal driving conditions, the front wheels receive a set percentage of the engine torque, and the rear wheels receive the rest.
Collectively, these are grouped into the 1000/2000 Series transmission family; transmissions within a family share the same basic dimensions, power input capabilities, and weight. Allison transmission families for the Bus Series include the 1000/2000 Series (B210, B220, B295), 3000 Series (B300 / B400), and 4000 Series (B500). [5]
The plug-in hybrid, called the Q7 e-tron TDI Quattro, is powered by a 3.0-litre TDI V6 turbo-diesel engine mated with an electric motor-generator placed in the 8-speed automatic gearbox to provide a maximum output power of 190 kW (255 hp) and a maximum torque of 600 N⋅m (443 lbf⋅ft) four-wheel drive.

The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
Output is transmitted via Audi's quattro generation IV all-wheel drive system, initially using the Torsen T-1 50:50 dynamic centre differential, and from 2007 for the 2008 model year, utilising the Torsen T-3 asymmetric dynamic centre differential, with a "default" torque distribution of 40 percent to the front axle and 60 percent to the rear ...
