Following a teaser image of the luxurious interior earlier this week, the new model arrives as one of Benz’s “most beautiful and exclusive S-Class cars of all time”, according to the carmaker.
Buyers will no doubt expect nothing less, as Mercedes has had more than 40 years to get it right with its last topless luxury four-seater appearing in 1971.
Joining the S-Class Coupe, the Cabriolet aims to offer the roofless experience combined with the comforts of the coupe in what Mercedes calls a “comprehensive warmth and wind protection concept”.
An optional Warmth Package includes neck-level heaters, wind protection and an intelligent, fully-automatic climate control system (that works with the roof up or down).
Add heated armrests and seats and S-Class aims to ensure passengers are never disturbed by a change in temperature from the outside air.
The Cabriolet uses lightweight materials in the boot and rear floor along with a folding soft top to match it with the Coupe weight-wise.
The soft top is made up of three layers and is available in black, dark blue, beige or dark red, and can be retracted in around 20 seconds at speeds of up to 60km/h.
Inside, customers can expect “a yacht-like atmosphere” with a choice of leather, nappa leather or Exclusive nappa leather along with six interior colour schemes, low wind noise and a ‘draught-free’ system.
Safety features include Pre-Safe Brake with pedestrian detection, cross-traffic assist, lane-keep assist, adaptive high-beam headlamps and Night View Assist Plus.
"After 44 years we are once again able to offer Mercedes aficionados an open-top car in the S-Class,” Mercedes-Benz’s Ola Källenius said.
“The new S-Class Cabriolet symbolises our passion for individual and timelessly exclusive mobility, which we share with our customers."
Two models will be available to overseas buyers from launch, with the ‘standard’ S 500 to be joined by an AMG version.
The S 500 is powered by a 4.7 litre twin-turbo V8 producing 335kW and 700Nm, matched with a nine-speed automatic. The S 500’s fuel figure is 8.5 l/100km.
The AMG version, called S 63 4MATIC Cabriolet, will also be on show in Frankfurt, packing 430kW and no less than 900Nm from its 5.5 litre bi-turbo V8 engine.
The V8 sends its power to all four wheels with a bias towards the rear, and is capable of propelling the S 63 to 100km/h from rest in 3.9 seconds.
But before you reach for the cheque book to put down a deposit, Benz has announced the AMG version will only be built in left-hand-drive (for now).
The 2016 Mercedes-Benz S-Class Cabriolet goes on sale in Germany at the end of this year, with an Australian arrival due sometime in 2016 - priced above the fixed-roof versions which range from $319,000 to $499,000.
