Seen as the master of customization for Mercedes-Benz vehicles, Brabus is also the in-house tuner of the Stuttgart manufacturer and one of the specialists in creating crazy limousines. The newest addition to Brabus range is the new S500 Plug-in Hybrid, called PowerXtra B50 Hybrid as a refference to its architecture. 
The power increase of the V6 engine by 52 hp and the boost in torque by 70 Nm bumps the system output of the hybrid sedan to 500 hp and system torque to 890 Nm (656 lb-ft). As a result, the luxury liner sprints from rest to 100 km/h (62 mph) in just 4.9 seconds. Due to the hybrid system, the top speed remains electronically limited to 250 km/h (155 mph).
And as this was not the only modification, the new Brabus comes with an aerodynamic-enhancement program, with sporty-elegant styling, with tailor-made wheels with diameters of up to 22 inches and exclusive options for the interior.
As the ideal complement to the performance upgrade, Brabus offers a fully stainless-steel sports exhaust system with four tailpipes in hallmark Brabus design for the S500 Plug-In Hybrid as well.
Also contributing to the striking designer looks and the even more dynamic and safer handling of the Mercedes S 500 Plug-in Hybrid and all other S-Class models are the tailor-made Brabus Monoblock alloy wheels with diameters of 19, 20, 21 or even 22 inches. 
To enhance the high level of dynamic handling of the hybrid sedan further, Brabus has developed a special control module that lowers the ride height of vehicles equipped with Airmatic by about 15 millimeters (.6 inches).
