Self Study Program 625 – Audi A3 saloon

VAG SSP 625. The sporty A3 saloon marks Audi’s entry into the world’s largest market segment, the compact four-door class. The third model in the successful A3 series features lightweight design, powerful and highly efficient engines, not to mention a number of high-end infotainment solutions and driver assistance systems. The Audi A3 saloon is the first notchback model from Audi in the compact premium segment and cuts an exceedingly sporty figure.

The design of the Audi A3 saloon combines classic notchback styling with the dynamics of a convertible. The flat roof line terminates at the C post and merges seamlessly with the shoulder line. The tornado line is a prominent contour edge and the wheel arches are flared to give a muscular look. The large round air vents, the three-dimensional decorative inlays and the air conditioner’s elegant control panel are testimony to the attention to detail that Audi devotes to every vehicle.

The large boot can be extended by folding down the rear seat backs. The sporty four-door model with its elegantly contoured notchback has all the strong-points of the successful A3 series.

Production at the Györ plant

The Audi A3 saloon and the S3 saloon are manufactured at the Győr plant in northwestern Hungary – the world’s largest engine plant – where Audi has been assembling the TT Coupé, Roadster and A3 Cabriolet for a number of years now. The company has built in Györ a state-of-the-art automobile factory with a complete process chain. All stages in the production process – from pressing the sheet metal to final assembly – take place in an area covering 250,000 m2.
