BRABUS ROCKET 900 Cabrio: Under this label, BRABUS presented the new fastest
and most powerful four-seater convertible in the world as a world premiere at the
IAA 2017. The new supercar is built based on the Mercedes S 65.
The open-top high-end supercar gets its name from the BRABUS ROCKET 900
6.3 V12 twin-turbo increased-displacement engine that powers it. The high-performance
power unit is built in the state-of-the-art engine shop in the BRABUS
plant in Bottrop.
The most complex operation on this engine is the displacement increase from standard
6.0 to 6.3 liters (366 to 384 cu in). The engine peripherals, which have been
redesigned in many aspects, are just as elementary for the performance increase.
On the exhaust side, special exhaust manifolds with turbochargers featuring a
larger compressor unit and turbine replace the production turbos. The conversion
also includes larger down pipes with a diameter of 80 millimeters (3.1 in) and a
stainless BRABUS high-performance exhaust with free-flow metal catalysts.
The intake side was also completely revised. It provides the engine with a generous
helping of additional combustion air. For this purpose, our BRABUS power
unit engineers developed the BRABUS 900 intake module, which includes a
special air filter box with larger intake cross-section and special filters, as well as
„Gold Heat Reflection“ sheathing for the intake pipes, which lowers the temperature
to enhance performance.
The BRABUS electronics specialists conducted extensive testing on test benches,
racetracks and public roads to program new mapping for injection, boost
pressure control, and ignition.
The elaborate conversion to the BRABUS ROCKET 900 6.3 V12 twin-turbo engine
results in unparalleled performance figures: At a low 5,500 rpm, the engine
pumps out 662 kW / 900 HP (888 bhp) of peak power. Even more gigantic is the
peak torque of 1,500 Nm (1,106 lb-ft) at 4,200 rpm. In the vehicle, peak torque is
electronically limited to 1,200 Nm (885 lb-ft).
The power is channeled to the rear wheels by a seven-speed automatic transmission
and a BRABUS high-performance limited-slip differential with a locking rate
of 40 percent. Thanks to the BRABUS RACE aluminum paddle shifters on the
steering wheel, the transmission can also be shifted manually. MOTUL supplies
the hi-tech lubricants for the entire powertrain.
This power unit makes the BRABUS ROCKET 900 Cabrio the world’s fastest and
most powerful street-legal open-top four-seater. From rest, the luxury convertible
reaches a speed of 100 km/h (62 mph) in just 3.9 seconds. The top speed is in
excess of 350 km/h (217 mph).
The unparalleled performance is accompanied acoustically by a symphony of
power: The ex-factory Bottrop BRABUS sport exhaust system with actively controlled
exhaust flaps can change the sound of the turbocharged V12 quasi from
