420 horsepower and an 8,250 rpm redline still isn't enough to make the B7 RS4 number one. The C7 RS6 is fast furniture, the B8 RS5 lost the manual, the C6 RS6 hid a twin-turbo V10 from America, and the B5 RS4 Avant got Cosworth Technology head work nobody here could buy. Number one is the 1994 RS2 Avant — 2.2 liter turbo five, 315 horsepower, assembled by Porsche on 911 brakes and Cup wheels. Every fast Audi wagon since is a remake of it. #ThreePieceUS #AudiRS #RS2Avant #B7RS4 #RS6 #Quattro #wagonlife #cars #wheels
