AMG GTS Posaidon tune to 690 bhp!


New hardware and software gives GT S Huracan-trumping performance
You could say that the Mercedes-AMG GT S’s standout feature is its deep bellowing V8. That’s not to say the chassis is lacking, but the twin-turbo unit was certainly a key ingredient in securing victory against the Porsche 911 Carrera GTS in the car's first head-to-head test (evo 204). And now, thanks to German tuning house Posaidon, that V8 is available with substantially more firepower.
Swapping the standard inboard turbos for uprated items, increasing the size of the intercooler and fitting a freer-flowing exhaust system has enabled Posaidon to fine-tune the ECU’s mapping so the engine now produces 690bhp and 553lb ft of torque.
