Plush open-top S-Class will reach the UK early next year, with a 577bhp S63 variant crowning the range
1 September 2015

Mercedes-Benz is promising supercar-like performance, an opulent driving experience and unmatched levels of interior luxury with its S63 4Matic Cabriolet - the 577bhp twin-turbocharged 5.5-litre V8-powered, four-wheel-drive model that spearheads its new S-Class Cabriolet line-up. 

Pictured here ahead of a planned Frankfurt show debut, the 2110kg four-seat rival to the Bentley Continental GT Speed Convertible is claimed to hit 62mph in 3.9sec, placing it ahead of many performance-orientated open-tops for off-the-line accelerative ability.

The car, which also produces 663lb ft, returns 27.2mpg and CO2 emissions of 244g/km.

As sister model to the new S-Class Coupé, the S-Class Cabriolet is the sixth and final member of the S-Class line-up. It is the first four-seat luxury drop-top model from Mercedes since the 112 series, which ceased production in 1971.

The S-Class Cabriolet adheres closely to the look established by the S-Class Coupé. The two share the same front-end design, including optional LED headlights encrusted with Swarovski crystals for the indicators and daytime running lights.

To accommodate what is described as the largest fabric roof applied to a current production car, the cabriolet adopts a new windscreen with greater rake and a more substantial frame for added rollover protection.

The multi-layer roof can be opened and closed in a claimed 20 seconds at speeds of up to 37mph.

Developed in Mercedes’ new wind tunnel, the car promises a drag coefficient of just 0.29. Double-glazed side windows and a butyl outer roof layer are claimed to provide class-leading noise suppression.

At 5027mm long, 1899mm wide and 1417mm high, the cabriolet’s dimensions mirror those of the coupé.

Inside, the two individual rear seats are electrically adjustable. Options include Mercedes’ turbulence-reducing Aircap system, which extends out of the windscreen header rail. Airscarf neck-level heating is also available.

The cabriolet rides on a modified version of the coupé’s platform. A revised aluminium bulkhead behind the rear seats supports the automatically extending roll bars, while reinforcement within the floorpan adds rigidity.

The cabriolet will come with the choice of two petrol engines from the start of UK sales early next year.

Included is a 449bhp twin-turbocharged 4.7-litre V8 in the S500 Cabriolet. It drives the rear wheels through a standard nine-speed automatic gearbox. No performance figures have been revealed, but combined fuel consumption of 33.2mpg is claimed, with average CO2 emissions of 199g/km.

Although not yet confirmed, Mercedes-Benz also plans to add a 621bhp twin-turbocharged 6.0-litre V12 to the new S-Class Cabriolet line-up in a plush S65 Cabriolet.

Mercedes should have stuck to their guns and made the Ocean Drive concept a reality with a four-door drophead to give it a true USP. They could have had pop up bollards in the B-post in case of a roll over as well as ones in the backseat for the sake of safety. Instead they just went the "me too" route and the world is still a bit dull as a result.

Given that this will, I imagine, cost a six-figure sum, how can Mercedes-Benz justify making it look EXACTLY like the forthcoming C-class cabriolet, albeit scaled up by 25%. If I were in the market for such a car, I would want far more distinctiveness and exclusivity. That generic front end, shared with everything from the A-class upward, looks cheap, plastic-y and unworthy of a very expensive luxury coupe or cabriolet. The shut line between the bonnet, wings and nose is too wide and will always look uneven as the angle changes around its perimeter. I'm sure it will be a technical tour de force, but its appearance is another major disappointment, IMHO.

Agree with Daniel Joseph about MB's panel gap problems. If MB can't or won't reduce the width and inconsistency of its panel gap, why then, in this model, does the perimeter of the bonnet continued by the body metal (rather than have the edge of the bonnet stopped by eg. headlamps & grille) as a result of which the problem appears worse? In any case, this kind of bonnet detailing is ugly irrespective of tightness of shutline, but many manufacturers are doing it.

Mercedes-Benz hit the bull's eye with the SL Coupe/Cabrio. What a beautiful car; it has the tech to back it up. Superb!

S Class even!

For Mercedes' flagship cabriolet it lacks any wow factor or specialness. I agree a 4-door cabriolet would be stunning and would be Mercedes' answer to RR's signature suicide doors. It does look like a XL version of the new C-class coupe and also looks like an E-class cabriolet from the side profile with the top up. I am hoping Mercedes will not end up like Audi or BMW where all their models looks all too similar to each other. The shut line on the hood or bonnet is a disturbing trend on newer Mercedes. I too don't like to see that seam cutting across the front end. I miss the characteristic classic Mercedes grille that is built into the bonnet, or having the cut line just about the headlight or grille opening to hide the seam or cut line, but many car makers are making the bumper piece as large as possible including migrating up the hood to make future design changes easier and less costly. Retooling the plastic parts is much cheaper than revising the sheet metal. This may make economical sense, but this is a Mercedes afterall. I'm sure this S-class cabriolet will look much better in person as it's grand scale is hard to capture in photos.

I might also add, there could be opportunity to make a S-class 4-door cabriolet and add it to their Maybach line.

The W111 in the background is better looking.

The general consensus is that the W111 is one of the best looking Mercedes. Along with its contemporary RR Corniche, this pair must be the two best looking full sized convertibles. I guess parking this new S class convertible next to the current RR offering will show up the Merc's styling shortcomings. No facelift will be able to fix the bonnet opening.

Not a wow factor at that price well under £100k fine.
