Audi's Sporty AS series has a new member, the RS3 Sportback. The difference to the "normal" A3 is striking - there's a roof spoiler and a large rear diffuser with a double exhaust and at the front a sporty radiator with large air-intakes. The silver exterior mirrors are also typical of the RS models. The car goes zero to 100 kilometres an hour in 4.6 seconds. But it doesn't come cheap.
