Displacement increase to 4.4 liters
Before the optics, we take care of the drive technology, which is simply mandatory at Brabus. Normally, a four-liter biturbo V8 with 585 hp and 850 Nm of torque does its job in the AMG G 63. Pushing the engine to 900 hp and 1250 Nm of torque (!) required more than just a little software optimization. Brabus got its hands dirty and increased displacement from 3982 to 4407 ccm. For this purpose, the cylinders were bored out to a diameter of 84 mm, oversize pistons including forged connecting rods and a milled and finely balanced crankshaft with a stroke of 100 mm were installed.
A special ram-air intake system forces air into the new turbochargers with larger compressor wheels and reinforced axial bearings, which release the excess boost pressure to the outside via a blow-off valve. Injection, ignition and boost pressure are controlled by newly tuned engine electronics, while a new high-pressure fuel pump ensures constant fuel pressure. The V8 sound escapes from the side of the black-clad stainless steel tailpipes, which should only be filtered to an insignificant extent by metal cats in the sports downpipes and new OPFs. An in-house coilover kit with a lowering of up to 45 mm and adjustable damping keeps the load together better in curves.

More practical door hinges
It is also dark inside, which is almost completely covered with particularly soft, black leather. There are also special quiltings on the seats, door panels, floor and trunk. What is not covered by animal skin is adorned with carbon or decorative strips made of – you guessed it – dark chrome. A speedometer up to 300 km/h testifies to the additional power in the bow. Practical detail: Brabus installed new door hinges, which now allow the portals to be opened wide by up to 90 degrees and make boarding easier.
