Test Fest : Best New Sport / Performance Car Over $50,000

For many, this is the most exciting category but also the hardest to evaluate. Six models are in contention, each sporting a slightly different persona: there are two true sports cars, the Audi RS4 and BMW M Coupe, three performance sedans, the Audi S6, BMW 3-Series Coupe and Lexus GS 450h, as well as one American icon, the Mustang GT500.
