German tuner Brabus has released performance kits for the new Mercedes-Benz V8 biturbo engines of the latest S and CL 500 (US: S550 and CL550) as well as the S and CL 63 AMG models. Depending on the model and the level of tuning, the kits boost power output to up to 620hp and a peak torque of 1,000Nm. In addition, there are aerodynamic-enhancement components made from exposed carbon fiber, custom-tailored tire/wheel combinations with diameters of up to 21 inches, and interior options.
For the S 500 and CL 500 models, the Germans offer the Brabus B50 – 490 PowerXtra CGI performance kits that sell for € 4,900. The Brabus PowerXtra module is a plug-and-play device that is integrated into the engine electronics. After the installation the 4.7 liter eight-cylinder biturbo engine produces a powerful 490hp, up from standard 435hp. Peak torque grows to 780Nm.
The Brabus B50 – 520 PowerXtra CGI performance kit, available for € 5,900, results in a power increase by 85 horsepower for both 500 models. In addition to the PowerXtra module, this version includes a supplementary intercooler. Equipped with this kit, both sedan and coupe reach a top speed of 300km/h in combination with the Brabus Vmax Unit. Rated power output is 520hp with a peak torque of 820Nm.
In addition to the auxiliary control unit for the engine electronics, the two Brabus power upgrades for the S 63 and CL 63 models also include a water-to-air intercooler powered by an electric auxiliary pump. For the S 63 and CL 63 models not equipped with performance package they offer the Brabus B63 – 584 PowerXtra CGI performance kit for € 5,900. It bumps power output by 40hp.
For all 63-series models equipped with performance package Brabus offers the Brabus B63 – 620 PowerXtra CGI version, which also costs € 5,900. As the name indicates, after the conversion the biturbo engine produces 620hp at just 5,500rpm. Simultaneously peak torque grows from 900 to 1,000Nm, available between 2,250 and 3,750rpm. In S 63 and CL63 models with Brabus B63 – 620 PowerXtra CGI tuning sprint time from 0 to 100km/h is shortened to 4.3 seconds. In combination with the integrated Brabus V/max Unit, top speed increases to up to 320km/h.
Nex to the tuning of the 5.5 liter engine a sport exhaust system with exhaust flap control is available. At the push of a button on the steering wheel the driver can choose whether to enjoy the V8 sound in the quiet and unobtrusive ‘Coming Home’ or in the markedly throaty ‘Sport’ mode. The fully stainless-steel exhaust system features two ceramic-coated tailpipes.
To transfer the increased power to the road with minimum slip, Brabus offers a limited-slip differential with a locking rate of up to 40 percent for the S 63 and CL 63 models. Other options include a carbon fiber body kit for the S 63 AMG and custom-tailored Monoblock alloy wheels with diameters ranging from 19 to 21 inches for all Mercedes S- and CL-Class models. The wheels are mounted with Pirelli or Yokohama high-performance tires.
Upon customer request BRABUS also refines the interiors of S-Class sedans and CL coupes to suit the owners’ personal tastes.
