Custom Mercedes fans have quite the treat coming up from Brabus in the form of a lot of engine. Actually a lot of engine is an understatement.

Mercedes already offers pretty impressive powerplants to begin with but specialized tuners can certainly ring the performance out of them to a new point.

As one of the most popular Mercedes specialist tuners around, Brabus offers a crazy service for the V8 engines the three pointed star puts in the front end of the rich people carriers.

The 4.7 liter twin-turbocharged V8 engine starts at 435 horsepower and it can be upgraded to 482 or 520 ponies by virtue of reprogrammed ECUs and added intercoolers.

If we’re speaking of 5.5 liter BiTurbo V8 one finds within the Mercedes S63 and CL63 AMG models, Brabus went pretty much to the same route but performance is predictably more incredible.

Using an ECU remap, an added water-to-air intercooler, an electric auxiliary pump the output of horsepower gets raised to 584 and even 620 when there’s an AMG Development pack included to the equation.

Brabus have not messed about with the appearance the Germans used on the aforementioned Mercedes models but they did remove the speed limiters so now we can get to the point where 199 mph is a possibility.
