The number in designation means the power. External aerodynamics kits for the Brabus Rocket 900 with carbon elements is almost entirely repeats similar to a modest modification of Rocket 850 based on Mercedes-benz S 63 AMG W222. The same applies to interior design, which is decent for a fee may be supplemented by a package iBusiness. But on the technical part of the changes are more serious. The amount of the standard 6.0-liter V12 twin-turbo has been increased to 6.3 liters, and its capacity increased from the original 630 to 900 hp Maximum torque at the same time increased to 1500 Nm against the original 1000, but had to limit at around 1200 Nm. Thrust is transmitted to the rear axle via an upgraded 7-band automatic transmission. On acceleration from 0 to 100 km/h tuning Brabus Rocket 900 is spending 3.7 seconds (- 0.6 sec.), And up to two hundred sedan accelerates in 9.1 seconds. The maximum speed, though remained limited, but the “collar” is now triggered at 350 km/h against 250 in the source code. I wonder how important it is to the person who is willing to pay for a car 348,000 euro.
