US 98 2.8 A4 commercial (30v in racing???)

[JP <palmerj@earthlink.net>]

AoA has a new commercial for the A4 30v... (kinda stupid) 
During the ad, the voiceover says the 2.8 has a _RACE_BRED_ENGINE_!
Coulda been 'race inspired', it was really late.

Had Audi been racing a V6 somewhere? I know Audisport had the V8s
running, and the 80s and A4 ran the 16v (the 10v and 20v 5's go without
saying).

How about the 5valve per cyl head? I have tried to tie the 30v engine to
any racing program without luck. 
Did Audi supply engines to a spec racing series? Does Audi have program
building 5valve Formula One engines???  Im runing out if ideas.
