5 cylinder audi turbo did you say ?
Wanna count championship wins?
Fiat twin cam = 10x constructors wins, 6x drivers wins
Audi 5cyl = 2x constructors wins, 2x drivers wins
Or individual world rally event wins?
Fiat (and Lancia using the Fiat twin cam engine) = 78
Audi = 24
Getting back on topic, any historical significance as "the original hot hatch" (such a cliche

) is offset by the fact that they made hundreds of thousands(?) of them.
What would a similar condition E30 M3 be valued at?
