Audi has always shown very production ready concepts. And unlike most, they translate the concepts well to production.
Would you rather they make pie-in-the-sky concepts that never make it to production? Or if they do, they look like crap?
I'd bet Audi is one of the best in keeping production cars faithful to the concept cars.
R8 concept car
Q7 concept car
A7 concept car
TT concept car
A5/S5 concept car
Allroad concept car
They have also made concepts that are more out in left field styling wise...
