The most obvious alteration to the Roadster is the lack of gullwing doors in favour of an electro-hydraulically retractable fabric roof that takes 11 seconds to open/close and upto speeds of 31mph (50km/h).
The bodyshell of the Roadster is 2kg over the coupé variant at 243kg. Mercedes said in a statement “In order to achieve handling dynamics identical to those of the Coupé, despite the lack of a fixed roof, the Roadster has two features designed to increase the rigidity of the bodyshell: the cross-member carrying the dashboard has additional supporting struts at the windscreen frame and at the centre tunnel, and a strut mounting stay between the soft top and the fuel tank makes the rear axle even more rigid. These features prevent unwanted vibrations from the start, and make the use of additional, weight-increasing vibration dampers such as those often
Long-term testing on a variety of different roads:
■All the components and systems are tested together in everyday operation. Loaded up to their permitted gross vehicle weight, the test cars are put through a precisely defined test programme on country roads, on motorways and in city traffic.
