A world-record speed of 330.6 km/h (205.2 mph) set on the high-speed test track in Nardo, Italy; BRABUS added to its extensive collection of automotive records with a Maybach 57 powered by a 730- hp (720 hp SAE net) / 537-kW BRABUS SV12 S Biturbo engine. It is the world’s fastest and most exclusive ultra-luxury sedan. The BRABUS engineers and test drivers bested their own record set in 2005 when a Maybach 57 powered by a BRABUS SV12 Biturbo engine with 640 hp (631 hp SAE net) / 471 kW was clocked at 314 km/h (195 mph).
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, two larger turbochargers, more efficient intercoolers, and a stainless-steel high-performance exhaust system with metal catalysts.
