Mercedes-Benz has officially unveiled the Mercedes-Benz SLS AMG Roadster. Have a look!
As might be expected from a sports car that was conceived from the outset as a soft-top as well as coupé, the Roadster appears a particularly neat conversion. It features new frameless doors with conventional hinges, designed to replace the exotic gullwing design of the coupé.
Because the SLS’s lightweight alloy structure was designed with an open-top body structure in mind, minimal reinforcements have been added, which also keeps weight gain to a minimum.
The thickness of the sill material is beefed up and there are struts off the centre tunnel to support the dashboard ‘cross-car beam’.
Structural stiffness at the rear is boosted by a strut between the soft top and the fuel tank.
Thanks to the roof and its hydraulic motors, the Roadster is heavier than the coupé — but by a fairly modest 40kg. That gives it a kerb weight of 1660kg.
Despite this, Mercedes claims very similar performance figures from the 563bhp 6.2-litre V8: 0-62mph in 3.8sec and a top speed just shy of 200mph.
