Self Study Program 313 – Audi A3 2004 Running Gear

VAG SSP 313. Development work for the A3 running gear focused on achieving sporty and agile performance, excellent handling, a high degree of road safety and outstanding comfort. These to some extent contradictory requirements were satisfied by introducing a wide range of new items whilst at the same time incorporating further improvements to existing features. Particular highlights in this respect are the new multiple-link rear axle and the electromechanical power steering.
