Coupe sedan, passed through the laboratory of the German Studio Posaidon, has the right to claim the title of the fastest chetyrehdverki on the planet among the serial. After refining the characteristics of its engine will do honor to any mid-engine coupe.
The factory version of the regular 4.0-liter V8 sedan develops 650 HP-this allows him to spend on acceleration to 100 km / h a little more than 3 seconds. But the tuners are people who are always "not enough". In the Studio Posaidon developed two options for fine-tuning this engine to a truly monumental performance.
In the RS 830 version, by flashing the motor control unit, increasing the boost pressure, changing the intake and exhaust systems, as well as the use of an intercooler, tuners achieve 830 HP and 1,100 Nm of torque from this engine. Accordingly, the dynamics is significantly improved: this sedan will be able to accelerate to 350 km / h instead of the regular 315, and the acceleration time to 100 km/h is reduced to 2.9 seconds-half a second faster than the factory version of the Mercedes-AMG GT 63 S.
In addition, this package of improvements includes reprogramming the transmission and suspension control units. Estimated transformation of the sedan into a monster in a fairly modest 24 thousand euros.
However, this modification has an even more hardcore version called RS 830+. More profound intervention in the motor (for example, replacement piston) allows you to get even a little bit of extra horses, and eventually return V8 reaches 880 HP and 1200 Nm.
The dynamic characteristics of this "Poseidon" were not disclosed, but we know that improvements could be made at any other AMG models with the same engine.
