Audi is a German automobile company that is a wholly-owned subsidiary of the Volkswagen Group. Originally seen as a conservative car maker, Audi began to change its image with the introduction of their "Quattro" four-wheel drive performance technology. With the intro of the Quattro they found great success in Rally Racing and became known as innovators in car technology. Since then, Audi has gone on to produce the successful A4 and A6 that are renowned for their luxury, make, and performance rivaling that of Mercedes-Benz and BMW.

An all-new A4 Cabriolet joins the lineup available with a 200hp turbo four-cylinder or a 255hp V6. The RS4 gets a 4.2 liter V8 engine that revs to a stratospheric 8,250 RPM and produces 420 horsepower. There will be no TT for 2007; instead it will be replaced by an all-new 2008 model.
