Rumored since 2012 and officially confirmed last year, the convertible->ke144 version of the brand-new Mercedes-Benz S-Class has finally come out to play on public roads in the form of camouflaged prototype.

Although there are no actual details for us to ogle at, the vehicle hidden under wraps is far from being a mystery. Styling-wise, the S-Class Convertible will be identical to the Coupe version we've seen in detail earlier this year, save for the retractable roof that will make sunny days more pleasant behind the steering wheel.

These spy shots suggests that the Germans are trying really hard to create the impression that the two-door will feature a hard-top, but we do know that Mercedes-Benz will go for a soft-top just like it did with the E-Class. Using a fabric top makes a lot of sense considering that a hard-top would eat up too much trunk space, a feature the S-Class can proudly brag about.

Engine-wise, the Convertible will also borrow all of its V-8 and V-12 mills from the Coupe model. Thus, the range will begin with the S500 and go all the way up to S65 AMG into 600-horsepower territory.

There's no information as to when the S-Class Convertible will be unveiled, but expect for this stylish drop-top to lose its covers at the 2015 Frankfurt Motor Show->ke235. Until then, make sure you stay tuned to TopSpeed for new details and spy shots that will most certainly occur soon enough.

Why It Matters

Mercedes-Benz is finally stepping up to take on the BMW 6 Series Convertible with a drop-top version of its flagship sedan. What's more, Stuttgart will also give Aston Martin->ke13 and Bentley->ke15 a run for their money in this pretentious luxury->ke505 segment.

Interestingly enough, the upcoming S-Class Convertible will be the company very first such vehicle since 1971, when the topless variant of the W111 "Fintail" was axed after a 10-year production cycle.
