A lot of people seem to ask the question:
What is the difference between the Audi B5, B6, B7 and B8? The answer is easy, it is there year when they were built.
Audi A4 B5 (1996 - 2001)
The car that dominates BTCC championship, the model that propels Audi in BMW and Merc territory and created the German Trio instead of the German Duo.
Audi A4 B6 (2001 - 2005)
Total revamp, new chassis, new tranny, heavily revised engine
Audi A4 B7 (2005 - 2007)
Everything new except it's the same platform, incorporates Audi's new family look derived from Concept Nuvolari (same interior space and eerily identical cockpit)
Audi A4 B8 (2008 - )
Total new model compared to B7, which is essentially a heavily revised B6 platform
