2006 Audi RS4
The Audi RS4 quattro is the top Tier and fastest performing version of the Audi A4 range (above the Audi S4) of cars. It is a sports-focused compact executive car produced by quattro GmbH, in limited numbers, for German car manufacturer - Audi AG, part of the larger Volkswagen Group. It slots above the Audi S4 as the fastest, most sports-focused model based on the A4's "B" chassis.
The original (B5) version was only produced as an "Avant", Audi's name for a estate car/station wagon. The second (B7) version was released initially as a saloon/sedan, with the Avant following a short while later. A Cabriolet version was subsequently added.
The "RS" initials stand for RennSport (German), and is Audi's highest trim level, positioned above the "S" model specification of Audi's regular model line-up. Like all Audi RS cars, the RS4 pioneers some of Audi's latest advanced technology, and could therefore be described as a halo vehicle. Furthermore, it is only available with Audi's Torsen-based quattro permanent four-wheel drive system.
Its main market competitors include the Cadillac CTS-V,BMW M3, Mercedes-Benz C63 AMG, and the Lexus IS-F.
Top Speed: 155mph
