Next-Gen Mercedes-Benz SL To Be Based On AMG GT Platform

Fresh reports claim that the next-generation Mercedes-Benz SL will share its underpinnings with the AMG GT in an attempt to increase the sporty prowess of the brand’s most famous convertible.

Interestingly, Autocar reports that Mercedes-Benz‘s performance division, AMG, has been given the reigns for the engineering development of the new SL and has been working on the model alongside the recently-revealed GT Roadster.

By adopting the GT’s underpinnings, the new SL will combine a rear-mounted transaxle with a longitudinally mounted engine up front, optimized for the best possible weight distribution. Additionally, the SL will adopt the GT’s double wishbone suspension setup and could receive the German firm’s optional Air Body Control system.

The similarities between the duo won’t end there. Like the GT, the new SL will adopt lightweight aluminum body panels and the carbon fiber torque tube from its more agile and sportier sibling.

In terms of engines, the model will be available with the company’s new M256 inline six-cylinder engine joined by a small 15 kW electric motor and incorporating an electrically driven turbocharger, making for a total of 402 hp in standard tune.

A new AMG variant will also be added to the range with roughly 450 hp on tap. The family will then continue to be topped off with the SL63 AMG and SL65 AMG, the first of which will use the same 4.0-liter twin-turbo V8 of the new E63.

    If there is a drop top AMG GT, what sense makes an SL based of the same mechanics?

    • Vassilis

      It will probably be softer, heavier and more luxurious. Closer to a Continental.

      • From sporty to softer it’s go AMG GT > SL > S-Class Cabrio.

        The SL is gonna have a pretty small niche in the Mercedes lineup, but then Mercedes doesn’t shy away from selling many different models where only one of two is strictly needed.

      • Miknik

        Well certainly it has to be, but then either the “sport” AMG platform will be compromised in the next generation weight wise, or the SL will be a compromise in terms of Bentley fighter…

        I still think the drop top ANG should simply be an SL. The Bentley has an S-Class convertible to play with….

        • Vassilis

          Why will the platform be compromised? It doesn’t need to be heavier. The rest of the SL components may add weight to the car. Better sound deadening, different materials, the roof mechanism etc.

        But if we look purely from a market perspective, you will have only 2 kinds of convertibles in that price point.
        Sports roadsters : Jaguar F-Type roadster, Ferrari California T, Porsche 911 Turbo cabriolet, Mercedes AMG GT roadster,
        Luxury cabriolets : Bentley Continental GTC, Aston Martin DB11 Volante, Mercedes S-class cabriolet, Rolls-Royce Dawn

        So as we see, the GT and the S have a clear market segment and competition, meanwhile the SL will still try to fit somewhere between them and I don’t think that would help his sales numbers.

  • Elmediterraneo

    Current AMG GT : SLS AMG plaform
    MSA platform desgined by AMG : Next SLC and SL, 2nd generation AMG GT.

    So as we know, the AMG GT is a front mid-engine car, but a V12 wouldn’t be too big and heavy for that position ?

  • Tumbi Mtika

    Make it a supersports model. The only possible way this would have a clear segment, is to gun for at least the F488 and McLaren 720P-I mean S. If they keep this stationed where it is, they are going to kill this model.

  • nauticalone

    These are MB’s I really like…in large part because they still come with console mounted gear shifter.

  • U8INIT

    Their vehicles are moving more and more upmarket…sheesh…

  • smartacus

    ha! i knew it!
    Oh the next SL is gonna be made with AMG’s help?
    Then it’s gonna have a rear-mounted transmission.

    -and what’s the other rumor about the next SL having 4 seats?
