Ahead of its debut at the IAA Frankfurt Motor Show 2015, the upcoming Mercedes-Benz S-Class Cabriolet has been filmed testing once again. This particular test mule is believed to be the potent Mercedes-AMG S63 Cabriolet variant.
The key giveaway that the tester in question is indeed the S63 Cabriolet model is its overtly aggressive body. That body includes new front and rear bumpers incorporating larger and more overt air intakes. Additionally, the rear is characterised by traditional AMG quad exhaust pipes hinting at the potent performance the car will offer.
Although unconfirmed, it seems likely that the car will also be dubbed the Mercedes-AMG S63 Cabriolet in line with the German firm’s ditching of the ‘Benz’ name in its AMG branded models.
Unsurprisingly, power from the S63 Cabriolet’s 5.5-litre twin-turbocharged V8 will remain identical to the coupe. That means it will deliver 577 hp and 664 lb-ft of torque helping to rocket the car to 100 km/h in 4.2 seconds as well as an electronically limited top speed of 250 km/h.
This will be the first time the S-Class has ever been available cabriolet configuration and when the car does launch, it will essentially be in a class of its own. The less technically advanced Bentley Continental GTC, Rolls-Royce Phantom Drophead Coupe and upcoming Rolls-Royce Dawn will be its closest rivals.
