What is it?
That’s because, says product boss Dirk Fetzer, acceptance of the car’s styling remains so high that AMG chose to focus investment on the technical side. As a result, there’s plenty that’s new under the cover: a 4.0-litre V8 bi-turbo unit replacing the 5.5-litre, a nine-speed wet-clutch automatic gearbox and a host of fancy technology recently introduced on the S-Class saloon.
For the sake of diligence, exterior changes include a new AMG panamericana grille and front apron with jet wing, plus new side skirts and OLED (Organic Light Emitting Diode) tail-lights.
The panamericana grille on the S63 ensures the model looks different to the two other S-Class cabriolet models: the entry-level S560 and the top-of-the-range S65. The S65 also has a panamericana grille but with a V-shaped cooling air intake, while the S560 has a standard Mercedes grille.
Pricing hasn’t been announced yet, but given that the coupé equivalent starts from £127,515 and the outgoing S63 cabriolet cost £135,675, you can expect the new model to be around £141,000. When you consider rivals the Aston Martin DB11 and Bentley Continental GT – typically considered more prestigious than Mercedes – are in the same price category, the S63 Cabriolet has a lot to prove.
