A lightly camouflaged prototype of the Mercedes-Benz S-Class Cabriolet has been spied during final testing phase.

A lightly camouflaged prototype of the Mercedes-Benz S-Class Cabriolet has been spied during final testing phase.

The S-Class Coupe is about to lose its fixed metal roof to make room for an electrically retractable soft top for the S-Class Cabriolet which is being described by S-Class project manager Martin Hulder as being "a car for the star gazers." Just like in our previous set of spy shots, there's a thin wrap of camouflage only on the rear half of the car and it seems there are going to be slightly different taillights compared to the S-Class Coupe.

The coupe has a chrome bar running the entire width of the rear end while the third brake light sits at the top of the rear window but for obvious reasons it will be repositioned on the S-Class Cabriolet. Overall, the design is largely carried over from the coupe but this prototype might not have all the final bits and pieces that will be installed on the production car.

Already confirmed for an official reveal later this year, the Mercedes-Benz S-Class Cabriolet will get the same array of engines as the Coupe, all the way up to the twin-turbo V8 5.5-liter inside the S63 AMG Coupe and the twin-turbo V12 6.0-liter from the S65 AMG Coupe. Expect pricing to significantly increase over the equivalent coupe which kicks off in Germany from €122,153.50 for the S500 Coupe whereas the S65 AMG Coupe begins at a hefty €244,009.50.

The Mercedes-Benz S-Class Cabriolet will likely receive its world premiere in September at the Frankfurt Motor Show.
