After being convincingly beaten by the BMW M4 in a 1/4 mile drag race due to traction problems, the Mercedes-AMG C63 S Coupe is back, and this time going up against the new Audi RS 5, equipped with quattro all-wheel drive. The RS5 is powered by a 2.9-litre twin-turbo V6 that makes 331kw/600nm, while the C63 S has the familiar 4.0-litre bi-turbo V8 under the hood, good for 375kw/700nm. Despite its extra power, the R1 519 246 C63 S weighs nearly 200kgs more than the R1 285 500 RS5 (and M4 Competition). How will it fare? Cars.co.za has helped us answer this question.
