Recently I noticed in the W210 gallery section of this site that there was a Brabus modification which (I assume) applied to the V8 engines in the 210 - and probably other ranges.
It is listed as a 5.7 litre conversion with a supercharger, all curtesy or Brabus.
I looked on the Brabus website, but this option does not appear in their lists. The closest one listed is the well-known 5.8 litre conversion giving 400bhp.
Looking around the internet, its said the conversion gave about 557bhp and top speed of around 300km/h.
Is there anything more to the story, of this apparent mysterious conversion, which anyone can add?
