Brabus tunes Merc's latest sports car to 591bhp and 750Nm of torque, set to debut at Frankfurt show

Mercedes might be showing its sleek new C-Class coupe and S-Class cabrio at the Frankfurt Motor Show, but German tuner Brabus might steal the firm's limelight with a beefed-up version of its AMG GT S sports car.
