Though the SLS AMG Coupe is now in showrooms, and we've just seen the first images of the 563 bhp convertible version a few minutes ago, they were developed in parallel and they're apparently so close in so many ways that choice will boil down to personal preference, not driving dynamics. The convertible has an electrohydraulically-operated soft top that can be closed or opened at up to 31 mph, and is claimed to be whisper quiet to its electronically-limited top speed of 197 mph

Testing is currently underway for the droptop supercar, and it will be seen in its final production form at the International Automobile Show in Frankfurt in September and in showrooms before the end of the year.

The convertible SLS is the second vehicle to be developed entirely by AMG, and as such, it is going to extraordinary lengths to ensure that the vehicle achieved handling dynamics identical to the Coupe. While the parallel development was underway, engineers focused on bodyshell rigidity, driving dynamics, the soft top, plus NVH (Noise, Vibration and Harshness).
