This is the Mercedes SLS AMG convertible which is undergoing testing, ahead of an expected on-sale date in 2011 or 2012.
The SLS AMG will be powered by the same 563bhp 6.2-litre V8 with 479lb ft of torque as the coupe, which will be unveiled at this year's Frankfurt motor show and go on sale next year.
That should mean the Mercedes SLS AMG convertible records a 0-62mph time of around four seconds, up from the coupe's 3.8s, because of the roof mechanism and the extra body strengthening.
The pictures clearly indicate that the Mercedes SLS convertible has traditional door openings as opposed to the gullwing doors of the coupe.
The 300SL, which is regarded as the SLS's spiritual predecessor, followed the same arrangement.
The price of the convertible is expected to start from £175,000, which is ten per cent higher than the coupe.
