Mercedes Benz Brabus Maybach - Feature

Feb 12, 2010

The SV12 S Biturbo evolution of the 6.3-liter displacement engine was originally developed for the BRABUS ROCKET, the four-door car based on the Mercedes CLS series. In October of 2006 it set a speed record for street-legal sedans of 365.7 km/h (227.2 mph), a record that still stands today.

For power increase of the turbocharged Maybach 12-cylinder engine from standard 550 hp (543 hp SAE net) / 405 kW to 730 hp (720 hp SAE net) / 537 kW BRABUS followed its tradition of increasing engine displacement. The BRABUS engineers developed a special crankshaft with longer stroke, precision-balanced piston rods and larger pistons to account for the increased cylinder bore. Displacement grows from standard 5.5 to 6.3 liters (335 to 385 cu. in.).

The inner workings of the engine are modified with precision-machined cylinder heads and special camshafts. The engine peripherals are tuned for more power with the help of a high-performance turbocharging system with special manifolds, larger turbochargers, more efficient intercoolers, and a stainless-steel high-performance exhaust system with metal catalysts.

Custom-programmed engine electronics coordinate the perfect interaction of all highperformance components and ensure that the engine meets stringent EURO IV emission limits. The standard 250-km/h (155 mph) speed limit is also eliminated. The peak torque of 1,320 Nm (974 lb-ft) is limited by the engine electronics to 1,100 Nm (811 lb-ft).

The enormous power of the BRABUS SV12 S Biturbo engine is transferred to the rear wheels via a reinforced five-speed automatic transmission. For the lubrication of the entire drivetrain BRABUS relies exclusively on ARAL high-performance lubricants.

The top speed of 330.2 km/h (205.2 mph) places enormous demands on tires and wheels. The BRABUS suspension engineers developed forged 21-inch BRABUS Monoblock VI lightalloy wheels specifically for the Maybach. The fully polished multi-piece wheels with six double spokes perfectly fill the space beneath the wheel arches. They are mounted in size 9.0Jx21 in front with size 275/40 R 21 tires, and in size 10.5Jx21 with size 315/35 R 21 tires on the rear axle.
