2006 Brabus SV12 S Biturbo Roadster

The Brabus engineers and designers have left no stone unturned to make the Mercedes SL-Class even sportier and more exclusive. Equipped with the Brabus SV12 S Biturbo twelve-cylinder twin-turbo engine that delivers 730 hp (537 kW) the SL 600 turns into the world’s most powerful roadster. 0 – 100 km/h in 4.0 seconds and 200 km/h after just 10.9 seconds speak to its prowess as does its top speed electronically limited to 350 km/h.

More power by increasing displacement is one of the core philosophies behind the Brabus SV12 S Biturbo engine. The displacement of the twelve-cylinder three-valve engine is increased from 5.5 to 6.3 liters with the help of a billet steel crankshaft, larger cylinder bore, special pistons and piston rods. The conversion also includes re-machining the cylinder heads and fitting them with special camshafts.

The peripherals of the twin-turbo engine also play a large role in the engine’s power yield. The Brabus engineers have also developed a completely new turbocharging system with two larger turbochargers and more efficient intercoolers. Metal catalysts with low back pressure let the Brabus SV12 S Biturbo displacement engine breathe more freely.

Special mapping for engine electronics and on-board diagnostics coordinate perfect interaction of the new components and guarantee an optimal symbiosis of maximum power yield and running smoothness. But that’s not all: The engine also offers exemplary clean emissions and excellent fuel efficiency in light of the available power. Like all Brabus high-performance engines the most powerful engine in the product lineup is lubricated with ARAL Synthetic Oil.

The Brabus SV12 S Biturbo engine offers impressive performance: Rated power output jumps from standard 517 hp / 380 kW at 5,000 rpm to 730 hp / 537 kW at just 5,100 rpm. Simultaneously peak torque grows from 830 Nm to 1,320 Nm, available from 2,100 rpm. Custom engine mapping ensures that peak torque in the car is limited electronically to 1,100 Nm.

For the latest SL generation the Brabus designers have developed a strikingly styled front fascia whose sophisticated shape reduces lift on the front axle. The large central air inlet further optimizes cooling of engine and front brakes. The high-quality Pur-R-Rim Brabus front fascia with its four auxiliary headlights is designed to be fastened to the original mounting points and thus simply replaces the production bumper.

The Brabus rocker panels smooth the airstream between the wheel arches and come with a useful extra feature: Pushing a button on the keyless-entry remote or pulling on an inside door handle activates four LED entrance lights on either side of the car. They illuminate the ground next to the vehicle and help to avoid unfortunate missteps in the dark.

The Brabus designer suit for the new SL is rounded out by the Brabus rear fascia with integrated diffuser. It too was designed to replace the original part and fits precisely in its place.

Just as important for a customized look are one-piece or multi-piece Brabus Monoblock light-alloy wheels that can be mounted on the two-seater in various designs and diameters ranging from 17 to 20 inches. The largest possible version for the R 230 series SL features multi-piece Brabus Monoblock VI, S or E wheels in size 9Jx20 in front with size 255/30 ZR 20 tires. On the rear axle the wheels measure 10.5Jx20 with Pirelli or Yokohama tires in size 305/25 ZR 20.

For further improving the incredible handling of the latest SL roadster Brabus has developed an electronic module for the ABC suspension that lowers the ride height by some 15 millimeters.

The Brabus high-performance brake system handles even extreme stress without any signs of weakness. It features vented and cross-drilled 375×28-mm mega-size discs and 12-piston fixed calipers on the front axle. The rear axle features vented and cross-drilled 355×28-mm discs and six-piston fixed calipers.

Luxurious and highly customized interiors are yet another Brabus specialty. The list of available product ranges from exclusive accessories such as genuine carbon-fiber door sills with illuminated Brabus logo to ergonomically shaped sport steering wheels with heated rim and shift paddles. Also available is a speedometer with 360-km/h dial and genuine
carbon-fiber interior trim in various colors.

In addition the company-own upholstery shop creates especially exclusive Brabus interiors from a combination of especially soft yet durable Brabus Mastik leather and Alcantara.
