Best of all - Posaidon RS 485 + now with 550 PS

Recently, Mercedes presented the new A-Class W177 (2018) in Amsterdam, sealing the official end of the W176. So far you are not yet with the new top model A45 AMG, and also the A35 AMG is still on test drive, but long it will probably not take much longer. Especially the facelifted version of the W176 as A45 AMG with 381 PS will probably not in the next years as underpowered apply and this is especially true if it is a Posaidon RS 485 + is. On the basis of the A45, Tuner Posaidon already has to feed 2016 of the A-Class 485PS and only one year later they topped that with that 500PS strong RS485 +. And whoever is of the opinion that the team from Mülheim-Kärlich is also mistaken.

the last expansion stage for the A 45?

True to the motto "the best for last", Posaidon is now launching an even more powerful version of the RS 485+, which with its insane 550 PS & electronically limited 660 NM torque should also impress drivers of an E63 AMG. The highlight is the fact that you can hardly see any change visually compared to the series and thus the A-Class from Posaidon is so little Wolf in Sheep's Clothing comes along. Due to the standard Spoilerpaketes that is however a little relative the inconspicuous is the A45 definitely not.

Optically Posaidon sets on understatement

The performance leap of 169 PS reaches Posaidon by the new two-liter turbocharged four-cylinder new turbocharger plus increase the intercooler and also a completely new Catless exhaust system made of stainless steel including 3,5 inch downpipe and electronic flap control. It goes on with motorsport spark plugs and a 4,5 inch intake but the highlight of the performance increase is definitely the now built Water-methanol injection which in combination with an in-house chiptuning software mobilizes the aforementioned 550 PS. Of course, the gearbox was also adapted to the additional power, which is currently compatible with the already mentioned 660 NM torque, by means of electronic locking.

However, Posaidon also announced that they are currently working on improved hardware, which may lead to the conclusion that "the very best“Will probably only come to the end! So that the extreme performance is adequately brought onto the road, the tuner installs a coilover suspension with adjustable dome bearings which of course also brings a subtle lowering. And an optional sports brake system can also be ordered at any time. Although not installed on the presentation vehicle, we already know from the predecessor, the Posaidon, the front axle can be equipped with two-part, perforated and potted 365 × 34 mm discs that are gripped by 6-piston calipers.
