The Mercedes-AMG GT R Roadster Black Series would have been one of the most exclusive two-seater convertibles on the market, although its specific qualities of a model without a roof made it no better suited to sport this imposing name. However, the POSAIDON RS 830+ represents this more radical model.
The Mercedes-AMG GT R Black Series It is a unique model in the world, with special aerodynamics and a significant reduction in weight, which translates into dizzying performance, a model not suitable for the faint of heart and where a high-performance circuit is its most natural habitat. The sports brand never planned the development of a Black Series on the AMG GT R Roadster, since its characteristics prevented it.
But for those who were left with the desire to enjoy the benefits of the «Black Series» in the open air, the Germans from POSAIDON have the solution in the form of a special edition and limited to only 750 units. Its about POSAIDON RS 830+, a true beast that brings the spirit of a Black Series to the AMG GT R Roadster, forgetting those who have the closed model that has no less than 730 hp of maximum power and 800 Nm of torque.

The German tuning specialist based in Mülheim-Kärlich has shown that this ambitious model could have been a reality. And it is that its technical package of optimizations on the 4.0-liter biturbo V8 engine reaches a maximum power of 880 hp and a maximum torque of 1,000 Nm, thanks to two new high-performance turbochargers, forged pistons, sports air filters, a new fuel pump and high-performance spark plugs.
In addition, the engine software features a new injection map, and the sports exhaust system has been reconfigured with new manifolds. The result is absolutely terrible, because Accelerates from zero to 100 km / h in just 2.9 seconds and reaches a top speed of 360 km / h. Scandal figures that have also required reinforcing the 7-speed dual-clutch automatic transmission “TCT SPEEDSHIFT”.
With a more exaggerated aesthetic and a large rear spoiler supported by two masts, POSAIDON offers a couple of levels for those who do not want to reach such figures, although both are still well ahead of the Black Series. The most basic level keeps the entire original engine intact, tweaking only the control unit and reaching 780 hp and 850 Nm. The intermediate level is based on extreme modification by lowering the specifications to 830 hp and 950 Nm.
