It's not the best kept secret that the Mercedes is developing a roofless version of the S-Class Coupe, but these are the best spyshots we've seen yet of the luxury convertible out piling the miles on its testing regime.
Estimated to appear in the Stuttgart firm's lineup just before the year is up, the S-Class Cabrio looks pretty much as you expect you to, sharing the coupe's swooping front lines and angular rear-end. As with the recently spied C-Class Convertible, the flagship drop-top will use a fabric hood design to save weight and space.
It’s not just styling that the latest member of the S-Class family will inherit from the coupe, as engines and in-car tech will also pass over. Kicking off the Cabriolet range will be the S500, featuring a 449bhp 4.7-litre bi-turbo V8, which will later be joined by the AMG-tuned 576bhp S63 and 630bhp S65.
Mercedes is similarly set to throw in crystal-infused LED headlamps and daytime running lights – designed to create a clear beam – and the Magic Body Control suspension system that scans the road ahead and leans the car into bends to compensate for body roll.
This also means we’ve now seen every incarnation of the new S-Class, a line-up including the Saloon and Coupe, as well as the recently launched extended-wheelbase Maybach S 600 and the mammoth Pullman luxury limousine.
The Coupe debuted in the UK last September, but sources at the firm don't expect to see the cabrio on sale until at least next winter. We expect it to add around £10-15,000 to the price of the coupe, which currently starts at around £96,000.
