Mercedes has officially unveiled the S-Class Cabrio following a leak earlier today.

Billed as one of the "most beautiful and exclusive S-Class cars of all time," the model closely echoes the S-Class Coupe but it eschews the fixed roof for a retractable three-layer acoustic soft top which is available in black, dark blue, beige and dark red.  Despite its relatively large size, the roof can be opened or closed in approximately 20 seconds at speeds up to 60 km/h (37.2 mph).

The interior also follows in the footsteps of the coupe but it gains an all-new THERMOTRONIC intelligent climate control system which promises to keep occupants comfortable regardless of whether the roof is opened or closed.  The convertible also offers an extensive assortment of upholstery choices including leather, nappa leather and designo Exclusive nappa leather.

Speaking of options, the model can be equipped with a Warmth Comfort package which includes heated seats, heated armrests and a heated multifunction steering wheel.  Customers can also order an AIR-BALANCE package which can waft a variety of fragrances into the cabin. If smells aren't your thing, you can order an optional AIRCAP automatic wind protection system or the familiar AIRSCARF neck-level heating system. 

The entry-level S500 Cabrio is powered by a twin-turbo 4.7-liter V8 that develops 455 PS (335 kW) and 700 Nm (516 lb-ft) of torque.  Buyers looking for something more powerful can opt for the S63 AMG or S63 AMG 4MATIC Cabrio which have a twin-turbo 5.5-liter V8 engine that cranks out 585 PS (430 kW) and 900 Nm (664 lb-ft) of torque.  It allows the all-wheel drive variant to accelerate from 0-100 km/h in 3.9 seconds before hitting an electronically-limited top speed of 250 km/h (155 mph).

The Mercedes S-Class Cabrio will go up for order in Germany in December and the first deliveries are slated for the spring of 2016.
