The stock Mercedes-AMG A45 is already one of the most impressing hot hatchbacks in the world, although with Posaidon’s upgrades, it can easily overcome its initial purpose.
An upgraded turbocharger, tweaked air intake, revised air cooling, water-methanol injection system, tuned ECU, spark plugs derived from motorsport and a new exhaust system have drastically transformed this compact car.
The result is a staggering 550PS (542hp) and 660Nm (487lb-ft) of torque. The latter figure was actually limited by the tuner, and the output represents a 169PS (167hp) and 185Nm (136lb-ft) of torque increase over the stock model, which needs 4.2sec for the 0-100km/h (0-62mph) acceleration.
This isn’t Posaidon’s first foray into this vehicle, as a couple of years ago, they presented a modified example with 485PS (478hp) and 556Nm (410lb-ft) of torque. That one could accelerate all the way up to 311km/h (193mph), and had better brakes, so it’s safe to say that this latest project will be even quicker.
Meanwhile, those that would rather wait for the Germans to unveil the new A45 are also in for a treat. The range-topping member of the A-Class family will arrive with more than 400 horsepower, and is rumored to get a special ‘Drift’ mode, just like the Ford Focus RS. Affalterbach might launch it in 2019 or 2020.
