Because Audi is the same stupid as BMW. The BMW M1 was BMW's first M Car. Today Audi has the R8, Mercedes the SLS AMG, and BMW has nothing. Audi was not Premium, it started become one only after the first S/RS cars and especially their new identity, thanks to single-frame grill. Everybody knows Mercedes's history and heritage, like the "Silver Arrows", the luxurious "S Classes" and such. Same goes for BMW with the M3 and the roadsters, overall very sporty daily cars. What about Audi? Nobody knows a shit, just as nobody knows how Apple started. But in reallity Audi has heritage. It was the most feared rival of the Lancia Stratos and later the turbocharged 5 inline Lancia Delta Integrale. Audi had the Quattro, with a turbocharged I5. That is Audi, and Audi should build the "Quattro Concept" with its TC I5 and Quattro AWD-system. Not some shitty "Plus", " DTM" and "GT" versions, like BMW does. What is there special about a A5/S5/RS5 DTM/PeakPikes? Nothing. The Audi Quattro should be that car. The A5/S5/RS5 is just another big coupé powered by a big engine, like the C/E Class, 4/6 Series and such.
Bring the Quattro! Not some stupid Q2 and Q4.
You also don't have a clue where Audi started
