The Brabus 900 engine conversion unleashes the performance reserves in the twin-turbo Mercedes-Benz G65 V12. The installation of a special billet-steel crankshaft with longer stroke, in combination with enlarged cylinder bores, the matching forged pistons and precision-balanced billet-steel conrods increases the displacement from stock 6.0L to 6.3L.
The modifications to the engine peripherals also play a major role in the enhanced power output. The engine uses modified exhaust manifolds, and the two production turbos are replaced with bigger ones, which produce a higher boost pressure than stock. The conversion also includes larger 80mm down pipes, free-flow metal catalysts and a stainless steel high-performance exhaust with actively controlled exhaust flaps.
Achieving optimal air supply for the engine is the Brabus 900 intake module, which draws air through a carbon scoop on the newly designed hood. Inside the intake manifold is an air filter box with larger intake cross-section and special filters as well as “Gold Heat Reflection” sheathing to lower the temperature. Precision-programmed mapping for injection, ignition and modified boost pressure control coordinate the perfect interaction of all high-performance components to lend the high-end engine a unique combination of explosive power delivery and the hallmark smooth-running of a V12.
The Brabus Rocket 900 6.3 V12 twin-turbo engine produces 900hp at 5,500 rpm and peak torque of 1,500Nm (electronically limited to 1,200Nm) at 4,200 rpm. In combination with the seven-speed automatic transmission and permanent all-wheel drive, the “One of Ten” shoots to 100km/h in just 3.9 seconds. Top speed is electronically limited to 270km/h.
At these speeds, a wider track optimizes the handling and safety, and consequently the badass SUV is fitted with the Brabus Widestar widebody version that adds a whopping 12cm to the width of the body. The model displayed at the IAA in Frankfurt sports the two Brabus Monoblock “PLATINUM EDITION” F and R wheel designs. The 11Jx23 forged wheels are shod with Yokohama Advan Sport tyres sized 305/35 ZR 23.
The Brabus Version V braking system was developed specifically for the heavy 800, 850 and 900 models based on the the G63 and G65. The front axle is fitted with vented and cross-drilled brake rotors measuring 412 x 38mm. Eight-piston aluminium fixed calipers, flex-steel brake lines and high-performance brake fluid also play a crucial role in the tremendous stopping power and outstanding fade resistance.
The Brabus 900 “One of Ten” is equipped with the Brabus Ride Control suspension, which is available for all G-Class models. The hi-tech suspension system was developed in cooperation with technology partner Bilstein and features two-way adjustable shocks front and back. A button on the center console enables the driver to choose from two setups – in the comfort position, the off-roader delivers exemplary ride quality. At higher speeds and with a sporty driving style, choosing the firmer sport setup results in more dynamic handling and even further increased safety reserves. In addition, the Brabus Ride Control suspension features automatic damper adjustment. When the vehicle sensors detect that a spirited driving style may result in certain parameters such as speed, lateral acceleration and steering angle leading to critical handling situations, the system automatically switches to the firmer sport setup within milliseconds. The sportier damper setup then further increases the handling stability. In return, the CAN control unit is also able to detect when the driver reverts to a more moderate driving style. It then automatically switches the shock absorbers back to the comfort position.
The company upholstery shop has also created a fine leather interior for the “One in Ten” limited edition in the combination ‘Mondial Vanilla’ and ‘Mondial Black,’ highlighted with red piping and vanilla-colored decorative stitching. The soft and breathable Mastik leather, which on the seat center sections is perforated and features shell-shaped quilting, is complemented by a starry sky in black Alcantara. Its hundreds of optical fibers change in sync with the ambient lighting of the interior.
The entire floor is lined with fine black leather. The presence of the powerful Brabus engine is also signaled in the interior with embroidered “900” logos on the front head rests. Even the trunk is completely restyled and equipped at the wheel wells with stylishly integrated storage boxes on the left and a subwoofer system on the right.
