Mercedes-AMG looks to be readying its new SL roadster for a reveal in the coming months, with a newly spotted prototype dropping most of its camouflage to give a good look at the car's final styling.
The latest images come after Mercedes recently released official details of the composite aluminium body shell used by the all-new SL roadster.
Mercedes claims the development process was particularly challenging given this new SL features a 2+2 seating arrangement, and will accommodate a wider variety of powertrain options. The priorities, it says, were to "present the driving performance characteristic of the brand with a focus on lateral and longitudinal dynamics, as well as to meet the high expectations in terms of comfort and safety".
A combination of aluminium, steel, magnesium and fibre composites was selected for the best balance of lightness and rigidity, with the new SL boasting an 18% increase in stiffness over the old model. Transverse rigidity, AMG claims, is up 50% over the AMG GT Roadster, while longitudinal rigidity has been boosted by 40%.
The main body shell - without the doors, bonnet, boot lid and other exterior fixings - weighs 270kg.
The reborn convertible will square off against the Porsche 911 Cabriolet with a range of hybridised straight-six and V8 engine options.
Multiple SL variants have been spotted side-by-side in minimal disguise, highlighting two different fabric roof options. This confirms Autocar’s previous reports that the SL will arrive with a traditional fabric hood in place of the folding hard-top arrangement that has been used for the past two incarnations.
Mercedes also confirmed that the 2+2-seat SL will be sold under the AMG brand only and will be offered with fully variable 4Matic+ all-wheel drive. While much of the SL's development was handled virtually, final on-road testing will soon include the north loop of the Nürburgring, hinting at the car's sporting ambition.
