Actually, the considerable serial output of 557 PS in the current Mercedes-Benz E63 AMG, should be quite sufficient for most uses. Should be; there is a surprising number of performance fans who can never get enough of such a potent vehicle.

Posaidon will gladly take care of this wish and by targeted measures generate so many additional PS in the E-class that no wishes will remain unfulfilled at all: Almost 300 PS extra turn the E63 AMG “RS 850” into a hunter on the motorway that will hardly find its match in longitudinal dynamics.

This performance treatment is made up of several mechanical and electronic components: For example, two upgrade turbochargers have been installed in connection with a changed charging air cooling. Furthermore, the suction paths of the 5.5 litres V8-biturbo drive have been optimised and the original exhaust system has been replaced by completely new exhaust technology, including turbo downpipes, racing sports catalysers and flap control.

Thanks to fine coordination of the motor electronics, the drive output has now been increased to an incredible 853 PS by Posaidon, corresponding to an additional performance of precisely 296 horses. The torque, increased from 720 Nm to 1,300 Nm will render you speechless, as well.

The maximum speed is at 345 km/h, electronically limited. The gearbox and the rear axle also had to be optimised as resist the increased stress.

In addition to the extreme development stage at 853 PS, the Posaidon specialists offer various other performance stages from 630 to 749 PS for all model series with M157 63 AMG biturbo motors, covering any customer wish.

Result: With the “RS 850” Posaidon proves how much potential there is in this drive, using it relentlessly.
