First the sedan, then the coupe and now the cabriolet: With the 800-hp (788-bhp) / 588-kW Brabus 800 V12 Biturbo twelve-cylinder high-capacity engine in the body of the open-top Mercedes E-Class Brabus further expands the legendary E V12 family. Like its brethren, the Brabus E V12 Cabriolet is a high-performance automobile of superlatives: the special model reaches a top speed of up to 370 km/h (231 mph) and is the world's most powerful and fastest four-seater cabriolet. It is built to order starting at EUR 478,000.
In building this supercar the Brabus engineers drew upon the know-how gained from building numerous E V12 sedans and coupes. Precision work was required to implant the Brabus 800 V12 Biturbo engine and a reinforced five-speed automatic transmission in the engine bay of the E-Class Cabriolet.
The most powerful engine in the Brabus lineup is based on the three-valve V12 engine of the current Mercedes S600 model. The company's engine-building shop reengineers this engine in all aspects. A special crankshaft with longer stroke and larger pistons in conjunction with increased cylinder bore bumps displacement from standard 5.5 to 6.3 liters (336 to 384 cu. in.). Further modifications to the engine's inner workings include cylinder heads optimized for mixture flow and sports camshafts.
The engine peripherals are reworked just as extensively: Two special exhaust manifolds with integrated larger turbochargers ensure a more efficient turbocharging process. The Brabus biturbo system is rounded out with four water-to-air intercoolers which also make a crucial contribution to the exceptional power yield. The stainless-steel high-performance exhaust system with four tailpipes was created specifically for the E-Class Cabriolet. The intake side was also completely redesigned: Under the custom-built hood with integrated carbon-fiber ram-air hood scoop is a completely newly developed intake manifold.
The perfect interaction of all performance-increasing measures is coordinated by newly programmed mapping for the electronic engine management system.
The Brabus 800 V12 Biturbo powertrain, lubricated with high-tech lubricants from technology partner ARAL, transforms the four-seater convertible into the most powerful and fastest of its kind in the world. 800 hp (788 bhp) / 588 kW at 5,500 rpm and peak torque of 1,420 Nm (1,047 lb-ft), limited electronically in the car to 1,100 Nm (811 lb-ft), are as unique as the driving performance this car delivers.
The power cabriolet is equipped with a Brabus high-performance limited-slip differential with a locking rate of 40 percent, and sprints from rest to 100 km/h (62 mph) in just 3.7 seconds. After 9.9 seconds the exclusive automobile already reaches a speed of 200 km/h (124 mph). The 300-km/h (186-mph) barrier shatters after 23.9 seconds. Depending on the final-drive ratio the Brabus E V12 Cabriolet has a top speed of up to 370 km/h (231 mph).
Sophisticated aerodynamic properties are essential for directional stability and active safety in a car capable of attaining such enormous speeds. The sporty yet elegant Brabus aerodynamic-enhancement components were fine-tuned in the wind tunnel, and like in Formula 1 racing they are made from ultra-light yet high-strength carbon fiber.
The Brabus front apron is shaped to reduce lift on the front axle and to guide a maximum amount of cooling air to the radiators and front brakes of the V12 model. Air outlets in the sides route the hot air away from the heat exchangers as quickly as possible. LED daytime running lights integrated into the apron give the Brabus E V12 Cabriolet an unmistakable appearance that can be quickly identified even in the rearview mirror.
For further improved directional stability at extremely high speeds and to further increase cornering speeds, Brabus widens the body of the E-Class Cabriolet. Newly designed front sport fenders widen the track and allow the installation of ultra-wide 9.5Jx19 wheels mounted with size 265/30 ZR 19 tires.
Special carbon-fiber rear fender flares add 60 millimeters (2.4 inches) to the width of the Brabus E V12 Cabriolet. They create space for ten-inch wide wheels mounted with high-performance tires up to size 295/30 ZR 19, supplied by technology partners Continental, Pirelli or Yokohama.
Professional engineering work was also invested into every detail of the suspension: special suspension components were custom-designed for the front and rear axle of the Brabus E V12 Cabriolet. They provide a much wider range of individual suspension settings. These components are joined by a Brabus coil-over suspension calibrated to the higher engine weight. The suspension was developed together with Bilstein and features ten selectable settings for bound and rebound front and back. The ride height can also be adjusted by up to 35 millimeters to suit each driver's personal preferences.
The Brabus high-performance brake system easily masters the car's incredible performance. It features 380 x 37 millimeter (15.0 x 1.45 in.), vented and grooved steel brake discs and 12-piston aluminum fixed calipers on the front axle. The rear stops on 360 x 28 millimeter (14.2 x 1.1 in.) discs with 6-piston aluminum fixed calipers.
Naturally the Brabus E V12 Cabriolet also features an especially exclusive interior. The first vehicle of the small-series production run, which celebrated its public debut at Brabus Middle East in Dubai, the company's own branch in the United Arab Emirates, breaks the mold in this area as well. The cockpit is clad in a perfectly finished combination of lipstick-red and black leather.
The ergonomically shaped Brabus steering wheel and inlays made from genuine carbon fiber on dashboard, center console and side trim add sporty highlights. The speedometer with 400-km/h (250-mph) dial bears witness to the unique performance potential of the open-top four-seater car even while it is standing still.
