This Mercedes-AMG E63 S may look like the previous generation model in the range topping S-trim, but when you drive it, you’ll know that it is far more superior. This is because the difference comes mainly from under the hood. This originally came with a biturbo 5.5-liter V8 engine that generates 585 horsepower, which is already quite powerful.
However, German aftermarket specialists Posaidon even got to push the already powerful car, to its maximum. It is now equipped with a 6.5-liter V8 engine that carries out 1,090 horsepower and 550 Newton-metres (406 pound-feet) more torque than the original engine, paired with a seven-speed automatic transmission. In fact, the tuners had to tweak the transmission and electronically limit the engine torque to ensure reliability. Initially, the untouched Mercedes-AMG E63 S with the V8 engine generated 1,350 Newton-metres (996 pound-feet) of torque. In this case, the speed restriction has become quite essential.
Naturally, hardware changes like upgrading the engine to 6.5 liters and boosting the turbochargers by increasing the boost pressure, with a new higher-capacity intercooler will make a car perform better. The new V8 also gets a stainless steel sports exhaust system, giving it a better soundtrack. An ECU remap was also required for the upgraded internals.
We won’t be very specific, but apart from the upgraded engine, the German tuner also played with the car’s suspension. It was also given a new set of original AMG wheels. Other than that, the speedometer has been upgraded so it could reach a maximum of 380 kilometers per hour, as opposed to the standard that had a limit of 320 kilometers per hour.
We may have heard of the hardware changes that the model got, however, we have not gotten details on how this car performs. But considering what has been added to the sedan, we can assume that it will be quicker and overall more impressive compared to the top of the line previous generation model, which could reach 62 miles per hour (100 kilometers per hour) from a standstill in only 3.6 seconds, and continue to a top speed of 186 mph (300 mph).
Having said that, this Posaidon-tuned Mercedes-AMG E63 S is definitely faster than the Bugatti Veyron. If you find that a four-digit horsepower might be too much for you to handle, Poseidon offers power kits that aren’t as crazy as this one - they offer 850 horsepower and 920 horsepower kits too.
