The natural competition for the Audi S5 is BMW's M3 coupe, and the two are near equals in performance in price--though TheCarConnection.com's car experts prefer the Audi's sleeker styling and standard all-wheel drive.
Mercedes-Benz offers a slightly more sedate coupe, the CLK550; it's powerful, and a Black Series edition can be had with ungodly amounts of power and torque.
It may not seem like a cross-shopped car, but the Dodge Challenger SRT8 can play musclecar even better than the Audi S5, though it's much larger, heavier, and cheaper.
