With its 2009 redesign, Audi upped the luxury performance-car ante with the A4. Its fresh face and benchmark interior distinguished it from its Mercedes C-Class and BMW 3-Series competitors, while its new dimensions made it the largest car in its class. Technological refinements for 2011 include an impressive 8-speed automatic transmission, and with the sure-footedness of Audi's world-class quattro all-wheel-drive system, a powerful engine, the availability of a wagon and the always-addictive performance of the S4 model, the lineup has a little something for everyone.
