Hmmm... checked the books, and no mention of the all-important *A-factor.

Audi 80C			CD 0.39, weight 950 kg
Audi 90				CD 0.39, weight 1060 kg
Audi 90Q			CD 0.40, weight 1200 kg
Audi Coupe GT5E			CD 0.36, weight 1060 kg
Audi 100CC Diesel		CD 0.30, weight 1210 kg
Audi 100CD			CD 0.30, weight 1210 kg
Audi 200 Turbo			CD 0.33, weight 1290 kg
Audi Turbo Quattro Coupe	CD 0.40, weight 1240 kg

I've leafed through other (older _and_ newer) books in my collection, but
found nothing but incidental mentions. The 100 Avants seem to suffer in
their CD: 0.34 was mentioned in one of the books.

HTH,

Tom

  an entire bee, if half the bee is not a bee, due to some ancient injury?
