The world’s fastest and most powerful four-seat cabriolet
These tremendously high speeds naturally place especially high demands on the aerodynamic-enhancement components, which were developed by the BRABUS designers in the wind tunnel. They are available for all S 63 and S 65 coupes and cabriolets. All bodywork components are manufactured from naked carbon with a high-gloss finishing coat.
The BRABUS front spoiler attaches to the front bumper and lends the two-door car full-blooded racing looks while reducing lift on the front axle at high speeds for further improved handling stability. Tailor-made carbon surrounds add even more striking emphasis to the large side air intakes in the front bumper. Naked carbon covers for the exterior mirrors add further, specifically sporty highlights.
The rear end of the open-top luxury liner also receives a visual upgrade. The BRABUS carbon diffusor provides the perfect backdrop for the two dual ceramic tailpipes of the BRABUS sport exhaust system. The BRABUS carbon rear spoiler on the trunk lid creates an aerodynamic balance between the front and rear axle. Carbon attachments for the side air outlets in the rear bumper round out the sporty lines perfectly.
Wheel and Chassis Refinement
A thrilling design, maximum quality and further enhanced driving dynamics are the outstanding traits of the BRABUS Monoblock wheels, which are available for the Mercedes S-Class Cabriolet in various sizes with diameters between 18 and 22 inches.
To be able to enjoy the enormous performance including the phenomenal top speed of the BRABUS 850 6.0 Biturbo variant to its full extent, the high-performance cabriolet is fitted with BRABUS Monoblock “PLATINUM EDITION” 21-inch forged wheels, which come in various designs. The use of state-of-the-art forging technology in their production results in an optimal combination of maximum strength and low weight. The wheels are mounted in sizes 9Jx21 on the front axle and 10.5Jx21 at the rear to make full use of the available space in the wheel wells. BRABUS selected Continental, Pirelli and YOKOHAMA high-performance tires of sizes 255/35 ZR 21 at the front and 295/30 ZR 21 on the rear axle as the optimal solution.
In addition, a BRABUS 22-inch tire/wheel combination is optionally available. The BRABUS Monoblock G “Platinum Edition” forged wheels of size 9Jx22 on the front axle are shod with size 255/30 ZR 22 tires, the size 10Jx22 wheels at the rear are fitted with tires of size 295/25 ZR 22.
The BRABUS lowering module is specifically calibrated to the use of these ultra-low-profile tires. It lowers the ride height of the open-top 2+2-seater by about 15 millimeters (.6 in).
The twin-turbo eight-cylinder engine in the bow of the cabriolet is constructed in the engine shop of the BRABUS Manufacturer in Bottrop equipped with state-of-the-art machinery. The displacement is increased from 5,461 cc to 5,912 cc (333 to 361 cc) by installing a forged BRABUS special crankshaft with longer stroke, increasing the cylinder bore and fitting the matching forged pistons and high-performance connecting rods. The two cylinder heads are also re-machined to guarantee maximum power delivery.
In addition, the engine peripherals are thoroughly revised. Two BRABUS special turbochargers with larger compressor units and modified exhaust manifolds replace the production turbos on the exhaust side. As part of the engine conversion, BRABUS also installs down pipes with a diameter of 75 millimeters (3 in) and special metal catalysts. The BRABUS stainless-steel sport exhaust system with butterfly valves electronically controlled from the cockpit optimizes the power delivery and the engine sound. In the “Coming Home” standard mode, the high-performance cabriolet has an even more subtle exhaust note than with the production system. On the other hand, when the valves are open, the eight-cylinder twin-turbo engine sounds as sporty as a super sports car.
The intake side of the turbocharged eight-cylinder engine was also revised thoroughly as a matter of course. Immediately conspicuous upon opening the hood is the specially designed and significantly larger BRABUS 850 intake module made from carbon. Just as essential for the power increase are the two more voluminous air filter boxes, which draw their air from a special duct in the hood, and new carbon air ducts with considerably larger cross sections. An especially striking feature is the BRABUS Gold Heat Reflection sheathing for the intake and charge-air pipes of the twin-turbo system.
As a result of the extensive modifications, the BRABUS 850 6.0 Biturbo engine delivers unrivalled performance figures. The engine produces its peak output of 850 HP at a low 5,400 rpm. Even more massive is the peak torque of 1,069 lb-ft, which is on tap between 2,500 and 4,500 rpm. In the interest of the longevity of the entire powertrain, the peak torque is electronically limited in the car to 848 lb-ft.
The company upholstery shop has just the right thing for customers looking for an even more customized interior. A BRABUS fine leather captivates not only with its practically endless variety of colors and materials, but above all with its outstanding quality of workmanship. BRABUS also refines the interior of the S-Class Cabriolet by customer request. This includes scuff plates with backlit BRABUS logo, whose colors change in sync with the various colors of the ambient interior lighting, and BRABUS genuine carbon interior components, which replace the production wood inlays and trim strips in the cockpit. Aluminum components such as the BRABUS RACE paddle shifters, pedals and door pins add markedly sporty highlights.
The BRABUS 850 6.0 Biturbo Cabrio is available as a complete car or can be built on the basis of any current Mercedes S 63 Cabriolet.
