The Audi A3 Sedan is a born winner. This sporty four-door model with an elegantly flowing notchback bears all the strengths of Audi’s successful A3 model line. Three engines will be available for this sedan starting this summer. The top-of-the-line model will appear before long: the Audi S3 Sedan with 221 kW (300 hp). It represents Audi’s foray into a new market segment.
