A new G-Class Cabriolet is officially in the works, with Mercedes-Benz announcing the first prototypes are undergoing testing.

Aiming to reaffirm its unwavering commitment to shaping the future of one of its most iconic nameplates, following the positive response to initial teaser details, Mercedes-Benz has announced prototypes of the G-Class Cabriolet are currently undergoing rigorous testing – the latter allowing the Three-pointed Star brand’s engineers to gather “comprehensive” data to ensure the open-top driving experience provided by the future G-Class Cabriolet production models is “unparalleled” and “unmistakably G-Class”. Dressed in subtle camouflage, the new drop-top G-Class is currently completing its first test kilometres in Austria, before making its way to Sweden, where it will be put through demanding winter testing.
When the series-production version will make its global debut remains unconfirmed. However, we wouldn’t be surprised if the German marque introduces this model towards the end of 2026. We also expect the G-Class Cabriolet will be available with the same petrol and diesel powertrains, with an all-electric derivative likely following in the future, employed by the current lineup.
As a reminder, locally, the G-Class can be had with the choice of three powertrains. This includes the firm’s 3.0-litre inline-six turbodiesel, which churns 270 kW (or 285 kW for short durations thanks to the incorporation of mild-hybrid tech) and 750 N.m of torque, the latter delivered to all four corners from a low 1 350 r/min; 4.0-litre V8 twin-turbocharged petrol, which produces 430 kW (or 445 kW with mild-hybrid electric boost) and 850 N.m; and an emissions-free drivetrain in the G580 with EQ Technology. The latter model’s dual electric-motor setup produces a combined system output of 432 kW and a tarmac-shredding 1 164 N.m of twisting force.
