Brabus-tuned Maybach fastest large sedan

A world-record speed of 330.6 kph was set on the high-speed test track in Nardo, Italy with a Maybach 57 powered by a 720 hp Brabus-tuned SV12 S Biturbo engine, making it the world’s fastest ultra-luxury large sedan. The Brabus engineers and test drivers bested their own record set in 2005 when a Maybach 57 powered by a Brabus SV 12 Biturbo engine with 631 hp was clocked at 314 kph.

The SV12 S Biturbo evolution of the 6.3-litre displacement engine was originally developed for the Brabus Rocket, the four-door car based on the Mercedes CLS series. In October of 2006, the Rocket set a speed record for street-legal sedans of 365.7 kph, a record that still stands today.

For the power increase of the turbocharged Maybach V12 engine from standard 543 hp to 720 hp, Brabus increased engine displacement and developed a special crankshaft with a 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 litres.

The standard 250 kph speed limiter is also eliminated. The peak torque of 1,320 Nm is limited by the engine electronics to 1,100 Nm.

The enormous power of the BRABUS SV 12 S Biturbo engine is transferred to the rear wheels via a reinforced five-speed automatic transmission.

The top speed of 330.2 kph places enormous demands on tyres and wheels. The Brabus suspension engineers developed forged 21-inch BRABUS Monoblock VI light-alloy 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 tyres, and in size 10.5Jx21 with size 315/35 R 21 tyres on the rear axle.

For further increased driving safety the BRABUS air-suspension module lowers the ride height by some 15 millimeters without compromising the unique ride comfort.

Interestingly, the car also comes with all the usual Brabus on-board gadgets and trim upgrades. We don’t know the price, but it certainly won’t be easy to digest.
