Posaidon has introduced its new tuning program for the Mercedes-AMG C63 / C63 S Estate.

Starting under the hood, the biturbo 4.0-liter V8 engine has been equipped with new turbochargers, a remapped ECU, an upgraded charge air cooling system, and a sports exhaust system that "connects directly to the turbochargers and includes motorsport catalysts."  Thanks to these modifications, the engine produces 690 horsepower (514 kilowatts) and 656 foot-pounds (890 newton meters) of torque.  For comparison, the standard C63 has 469 hp (476 PS / 350 kW) and 479 lb-ft (650 Nm) of torque while the C63 S develops 503 hp (510 PS / 375 kW) and 516 lb-ft (700 Nm) of torque.

The engine is connected to an upgraded seven-speed automatic transmission which enables the car to accelerate from 0-62 mph (0-100 km/h) in 3.4 seconds before hitting a top speed of 213 mph (343 km/h).

Customers can also order an upgraded rear differential, an engine start/stop system override and a "speed-trap update" which will show the location of speed traps on the navigation system.
