Audi finally grafts its new single-frame grille onto the A4 Cabriolet, one of the last models in the lineup to receive the new corporate nose. But the big news is what gets installed under the hood of the RS4 model, which is for overseas markets only. Equipped with a direct-injection, 420-horsepower V8 engine, this mobile suntan booth runs to 60 mph in less than five seconds. Quattro all-wheel drive and a dynamic ride control system help to maximize the Audi RS4 Cabriolet’s power and handling.
