Mercedes-AMG is updating its S-Class Coupes and Cabriolets 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 vehicles an even more independent look.

In the AMG S63 Coupe and Cabriolet, the handcrafted AMG 4.0-litre V8 bi-turbo engine with twin-scroll turbochargers and cylinder deactivation (Coupe) supersedes the previous 5.5-litre V8 bi-turbo. Despite the smaller displacement, the new engine puts out 603bhp - 26bhp more than the preceding model.

The AMG Speedshift MCT 9G transmission is also new to the Coupe and Cabriolet, as is the fully variable all-wheel drive system AMG Performance 4MATIC+.

At the same time with the new eight-cylinder Coupe and Cabriolet, the top-of-the-range 12-cylinder S65 Coupe and S65 Cabriolet are given a visual update with the Panamericana radiator grille. The handcrafted AMG 6.0-litre V12 bi-turbo engine retains its output of 621bhp and delivers a maximum torque of 1,001Nm.

"Having already undertaken major development work on our S-Class Sedan to further enhance driving performance and individuality, we are now making the same changes to the S63 Coupe and Cabriolet. The extensive modifications are designed to strengthen our leading position in this dream car segment in terms of driving dynamics, performance, equipment and comfort on long journeys. The S65 Coupe and Cabriolet, with their high-torque 6.0-litre V12 bi-turbo engine, remain the most elite form of the S-Class," stated Tobias Moers, CEO of Mercedes-AMG GmbH.
