Unlocking the potential of the M177.
While we all loved the M156/M159 naturally-aspirated 6.2-liter V-8s that Mercedes-Benz used in a variety of their AMG sports cars, the new M177 is here and packed with all sorts of potential that has us and many tuning companies drooling. It might not be as brutal, but it can sure pack one hell of a punch as Posaidon found out with their new Mercedes-AMG C63 and C63 S upgrade program.
The twin-turbocharged, hand-built brute that is the 4.0-liter M177 V-8 engine holds a tremendous amount of potential thanks to its forced induction. While the stock 510 horsepower in the C63 S is impressive, it’s nothing compared to output after the Posaidon treatment.
The 4.0-liter V-8 engine was given a new set of in-house turbochargers and larger intercooler system. A full exhaust from the turbochargers all the way to the tailpipes was installed to reduce backpressure and includes a pair of motorsport-grade catalytic converters. The engine was also subjected to a software tune that deactivates the stop-start function and integrates all of the new upgrades. As a result, Posaidon was able to give the new Mercedes-AMG C63 and C63 S a total of 700 horsepower and 656 lb-ft. of torque – good for a 0-62 mph time of 3.4 seconds and 213 mph top speed.
Thanks to the increase in power, the rear wheels have quite the task of achieving grip. So, Posaidon can optimize the AMG Speedshift MCT seven-speed gearbox or install an upgraded rear differential (for non C63 S models) in order to reliably put down the power.
As a final option, those with lead feet can opt for the Posaidon Speed Trap update. This system integrates directly into the COMAND Online navigation system and alert drivers of speed traps.
The new Posaidon upgrade packages are currently available for both the Mercedes-AMG C63 and C63 S coupe, sedan, and wagon variants.
