AUDI AG has now officially confirmed that the Audi A1 will receive the long-awaited quattro transmission. Great news!
As announced at the Paris Motor Show back in the fall of 2010, Audi is also bringing the permanent all-wheel drive system to the premium subcompact class. Consistent traction, a high level of driving safety and exciting dynamics – the A1 with quattro drive will be the first car in this segment to power all four wheels.
The youngest member of the large quattro family uses a technology very similar to that used in the A3 and TT model lines. At its core is an electronically controlled, hydraulically actuated multi-plate clutch located in front of the rear axle for an optimized distribution of weight. Inside is a package of plates that rotate in an oil bath.
During normal driving, the clutch sends most of the engine’s power to the front wheels. If the front axle loses grip, the clutch can instantly transfer torque to the rear axle by forcing the plate packages together. A pressure reservoir helps the electric pump to develop the necessary oil pressure.
