With far less bulky camouflage across the prototype, new details can be seen such as the lower air intakes and size of the SLR-like tail lamps.
The SLS Cabriolet will be powered by a finely-tuned version of AMG’s 6.2-litre V8 engine producing peak power of 420kW and 650Nm.
This is coupled to a seven-speed dual-clutch transmission which has been mounted at the rear to improve weight distribution, connected to the engine with an ultra-light carbon-fibre shaft.
As is the case with many convertibles, it is likely to be slightly slower off the mark than its hard-top sibling which accelerates from zero to 100km/h in 3.8 seconds with a top speed of 315km/h.
The two new models will go on sale in the first quarter of 2010 to coincide with their debut, for a limited run of only two years.
