Standard equipment on the S500 AMG Line includes 19in alloys, LED headlights, sat-nav, heated front and rear seats and a leather interior.
The S63 adds more AMG bodykit, an upgraded sound system and an AMG sports exhaust system, while upgrades to the S65 include 20in alloys and a heated steering wheel.
Pictured here at the Frankfurt motor show, the S63 is a 2110kg four-seat rival to the Bentley Continental GT Speed Convertible. Its 0-62mph time places it ahead of many performance-orientated open-tops for off-the-line accelerative ability.
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.
