The new SLS AMG GT Gullwing and Roadster

The SLS AMG Coupé that appeared in 2009 was the first vehicle developed independently by Mercedes-AMG. The new gullwing model was followed in 2011 by the open-top SLS AMG Roadster as well as the SLS AMG GT3 customer sports racing car.

With the new SLS AMG GT, available as a Coupé and Roadster, the model range has now grown to five variants. The sixth model is expected to follow in 2013 in the form of the new Mercedes-Benz SLS AMG E-CELL: Mercedes-AMG is planning an exclusive series-production run of the purely electric-driven super sports car.

The specific assembly area for the SLS AMG is located in the largest Mercedes-Benz production plant in Sindelfingen. The AMG 6.3-litre V8 engine comes directly from the AMG engine workshop in Affalterbach, where it is hand-assembled according to the traditional “one man, one engine” philosophy.

The new 2013 Mercedes-Benz SLS AMG GT boasts enhanced driving dynamics and even better on-track performance. With an enhanced maximum output of 591 hp (435 kW), a re-calibrated AMG SPEEDSHIFT DCT 7-speed sports transmission and the redeveloped AMG Adaptive Suspension, the new SLS AMG GT – which is available both as a Coupé and a Roadster – has raised the bar even higher. As a further highlight, a new optional AMG designo STYLE interior package is now also available for the 2013 SLS AMG GT.

According to Tobias Moers, Board Member and Head of Overall Vehicle Development for Mercedes-AMG GmbH: “The new SLS AMG GT demonstrates the sort of potential which lies in AMG’s super sports cars. With its even higher levels of performance, the SLS AMG GT excites out on the race track in particular by providing an emotionally enjoyable and passionate driving experience.”

The interior of the new SLS GT include a designo leather finish for the entire dashboard, the beltlines and door armrests, the handrest on the centre console, AMG floor mats in black with porcelain leather edging, roof lining in Alcantara ® porcelain, and the parcel shelf (Coupé) or roll-over bar (Roadster). Seams finished in contrasting colours create exciting highlights and underscore the high-quality, hand-finished nature of this new leather package.

Available colour combinations include mocha brown/porcelain, titanium grey pearl/porcelain and mystic red/porcelain. The colours of all of the elements of the interior appointment such as the roof liner, carpet and centre console are perfectly matched to each other.

Other attractive optional extras for all SLS AMG models include (extract):

  • AMG carbon-fibre exterior mirrors
  • AMG carbon-fibre engine compartment cover
  • AMG Interior Carbon-Fibre package (carbon-fibre trim, trim on seat backrest and side, door sill panels)
  • AMG ceramic high-performance composite braking system
  • AMG Performance Media
  • AMG 10-spoke forged wheels in other colour variants
  • AMG carbon-fibre trim
  • AIRSCARF (Roadster)
  • Bang & Olufsen BeoSound AMG surround sound system

Mercedes-AMG has achieved the output of 435 kW (591 hp) through in-engine dethrottling measures in conjunction with an increase in peak pressure. The GT version of the AMG 6.3-litre eight-cylinder front mid-engine responds with even greater agility to accelerator pedal movements and excites with even sportier-tuned performance characteristics. The AMG SPEEDSHIFT DCT 7‑speed sports transmission located on the rear axle is more direct and spontaneous in the manual “M” transmission mode: thanks to newly developed gear change functions and optimised transmission control, it has been possible to shorten reaction time significantly.

When changing gears manually via the real metal shift paddles on the AMG Performance steering wheel, control commands right through to the noticeable gear change are executed markedly quicker than previously – all of which is ideal when striving to achieve some ambitious lap times on a closed-off race circuit.

The reaction time experienced by the driver is made even more emotional as a result of more distinct gear changes. The automatic double-declutching function when shifting down is also more pronounced in the SLS AMG GT. Due to an increase in engine torque in manual mode, the shift procedure is even quicker than previously – and is accompanied by some passionate acoustic feedback for the driver. Overall, the optimisation of the dual clutch transmissioncomplements the sporty nature of the SLS AMG GT perfectly.
