2012 Mercedes-Benz SLS AMG Roadster Revealed in Patent Designs

It's no secret that Mercedes-Benz is preparing a roadster version of its new SLS AMG 'Gullwing' and while we've already shown you spy photos of camouflaged prototypes in the past, these 'ghost' images from the design patents filed for the car, reveal the drop-top supercar in almost every detail.

The chief differences between the two SLS AMG variants concern the retractable soft-top and, judging by the position of the door handles, the conventionally opening doors of the Roadster model - even though there's a possibility Mercedes may use scissor-type doors like those found on the older McLaren SLR roadster.

Expected to make its world premiere during the 2010/2011 auto show season and go on sale late next year, the SLS AMG Roadster won't differ mechanically from its coupe sibling featuring the same 6.3-litre V8 with 571HP and 650Nm (479 lb-ft) of torque.

As with the 'Gullwing', power will be delivered to the rear wheels through a seven-speed dual-clutch transmission. However, the extra weight from the body strengthening might add a tenth or two to its test times.

It's far too early to know details about pricing but as is common with these types of cars, the Roadster model will probably cost a bit more than the 'Gullwing' version of the SLS AMG.
