There are aftermarket shops out there and then there's Brabus. The Bottrop-based company always pulls out all the stops to extract every last drop of performance from an AMG. Less than a year after giving the E63 S almost 800 horsepower, the tuner is back with an even stronger build. This time around, they went the extra mile and bumped the V8's displacement from 4.0 to 4.5 liters by boring out the eight-cylinder block to 84 millimeters (3.3 inches).
Brabus also installed larger pistons, a custom billet crankshaft, and eight bespoke piston rods to lengthen the stroke to 100 mm (3.9 in). On top of that, the tuner installed its own pair of turbochargers with a maximum boost pressure of 1.4 bar. The V8 now breathes through a new exhausts system fully made from stainless steel, while the modified intake improves air supply.
