But the members of the BRABUS R&D team wouldn’t be the top-notch engineers they are if they were satisfied with those achievements. And thus in mid-October of 2006 they once more made the trek to the world-famous high-speed circular track in Nardo, in the south of Italy. Under the keen eyes of the German Technical Inspection Agency (TЬV Sьd) the 348,000-euro ultra-performance automobile improved the world record for street-legal sedans to 365.7 km/h (227.2 mph).

The BRABUS ROCKET is powered by a twin-turbo BRABUS SV12 S engine, fitted into the tight confines of the four-door’s engine bay with almost surgical precision. The engine is based on the latest 600-series twelve-cylinder engine and was developed by BRABUS with the goal of combining maximum power with exquisite running smoothness and maximum environmental friendliness.

A special crankshaft, larger cylinder bore and larger forged pistons increase displacement from 5.5 to 6.3 liters (336 to 385 cu. in.). Airflow in both intake and outlet manifolds of both cylinder heads is optimized and sport camshafts are installed.

The engine peripherals also underwent numerous modifications: Larger turbochargers, a more efficient intercooling system and a stainless-steel high-performance exhaust system with four exhaust pipes and low-back-pressure metal catalysts are all part of the BRABUS Rocket engine concept. Newly programmed engine electronics orchestrate the perfect interaction of all new components and contribute not only to maximum power yield but also to meeting the latest EURO IV emission limits.

The BRABUS SV12 S Biturbo engine, also available for all current Mercedes-Benz 600 and 65 models with twin-turbo V12 engine, produces a maximum power output of 730 hp (720 hp SAE net) / 537 kW at 5,100 rpm. Peak torque is 1,320 Nm (974 lb-ft), but is limited electronically to 1,100 Nm (811 lb-ft), available from a low 2,100 rpm.

The top speed of 365.7 km/h (227.2 mph), limited electronically for street-legal operation to 350 km/h (217 mph), is not the only attribute that elevates the BRABUS ROCKET to the very top of its segment. The four-door is also among the fastest accelerating cars in the world: 0 – 100 km/h (62 mph) in 4.0 seconds, 0 – 200 km/h (124 mph) in 10.5 seconds, 0 – 300 km/h (186 mph) in 29.5 seconds are numbers as unique as this exclusive BRABUS automobile itself.

Power is transferred to the rear wheels via a modified five-speed automatic transmission and the BRABUS locking differential.

The BRABUS ROCKET engine and the entire drivetrain are operated with high-performance lubricants from technology partner ARAL.

To keep the enormous performance potential of the world’s fastest sedan safely in check at all times the vehicle’s aerodynamics, suspension and brakes were modified extensively.

Like all other BRABUS body components the BRABUS ROCKET front spoiler received its final aerodynamic touches in the wind tunnel. Its large air dams ensure optimal cooling-air supply for all radiators. More importantly, it reduces lift on the front axle and contributes to a further improved drag.

Its aerodynamic counterparts in the rear are the BRABUS rear spoiler lip for the trunk lid and the BRABUS rear apron with integrated diffuser. They increase downforce and create a perfect aerodynamic balance.

The BRABUS rocker panels calm the airflow along the sides. As an additional feature the rocker panels and the rear apron are equipped with integrated LED lights. Activated by the keyless-entry fob or by pulling on a door or trunk handle five LED lights an either side and in the rear of the vehicle illuminate the ground beside and behind the car.

To make the suspension even more agile and safe the BRABUS suspension engineers and test drivers in cooperation with Bilstein have developed a custom-calibrated height-adjustable coil-over suspension for the ROCKET. The gas-pressure shocks offer six selectable settings for bound and rebound.

Maximum stopping power is yet another active safety feature offered by the BRABUS ROCKET. The high-performance brake system features vented ceramic brake discs in size 375 x 36 mm (14.8 x 1.42 inches) and 12-piston aluminum fixed calipers on the front axle. Vented and perforated steel discs in size 355 x 28 mm (14.0 x 1.1 inches) and 6-piston aluminum fixed calipers on the rear axle complete this efficient and strong brake system.

The giant size of the brake components and the enormous vehicle performance necessitate the use of BRABUS Monoblock VI or S light-alloy wheels with 19-inch diameter. The BRABUS ROCKET features 8.5Jx19 wheels in front with 255/35 ZR 19 tires and 10Jx19 rims with 285/30 ZR 19 tires on the rear axle.

The BRABUS ROCKET also meets the highest expectations of the most discriminating customers when it comes to the interior: The cockpit is upholstered with soft and breathable BRABUS Mastik leather and Alcantara. Carbon-fiber applications are part of the sporty BRABUS interior as are an ergonomically shaped BRABUS sport steering wheel and the speedometer with 400-km/h (250 mph) dial.
