Mercedes-AMG is updating its S-Class Cabriolet with a host of technical and visual highlights. The new-design front end is dominated by the Panamericana radiator grille, which now gives the two-door, luxury-class Performance vehicle an even more independent look. In the S 63 4MATIC+ Cabriolet the AMG 4.0-litre V8 biturbo engine with twin-scroll turbochargers and cylinder deactivation supersedes the previous 5.5-litre V8 biturbo. Despite the smaller displacement, the new engine puts out 450 kW (612 PS) and thus exactly 20 kW (27 PS) more than the preceding model. The AMG SPEEDSHIFT MCT 9G transmission is also new to the Cabriolet, as is the fully variable all-wheel drive system AMG Performance 4MATIC+.
