AMG is on a roll, especially given the success and reception for the SLS AMG "Gullwing" last year. Now, the Affalterbach performance specialist is on the move again, this time with the development and testing of the new SLS AMG Roadster version, a car that is due for its debut at the September Frankfurt Auto Show.

Recent photos show the new SLS AMG Roadsters slightly disguised as they cover their test routes in Germany. The personnel responsible at AMG have already completed most of the work involved, verifying and testing the bodyshell design, weight distribution, engine position, center of gravity, handling dynamics, aerodynamics, ergonomics, crash behavior and production processes. Special testing procedures, such as a 10,000 kilometer run of the Nurburgring Nordschleife and 10,000 kilometers of city driving have been also undertaken by the development engineers.

Owing to the omission of the coupé roof and gullwing doors, the open-top SLS AMG has a reinforcing cross-member behind the seats which supports the fixed rollover protection system. The latest simulation software and extensive test drives on all continents make the 571 horsepower Roadster fit for its market launch in a few months time.
