Mercedes-AMG has revealed what is the most powerful S-Class cabriolet ever at the Detroit Motor Show overnight.

Employing the work of the company’s ubiquitous 6.0-litre twin-turbo V12, the new S65 chop-top makes 463kW and a colossal 1001Nm.

That’s enough torque to twist the most powerful bygone S-Class Cabriolet, the 1969 300SE, in to a fusilli stick.

The AMG driver’s package, standard on US vehicles, will raise that limit to 299km/h. A ceiling it could easily surpass.

Chrome lathers its front badge, side flics, front splitter and front grille. “V12 Biturbo” also features on its wings, and high-sheen ceramic wheels under its guards.

The AMG S65 will launch in the US this June, but expect to see it land in Australia for more than the S65 AMG Coupe’s $498,610.
