Longtime Mercedes-Benz tuner has released a performance package for the latest S500 and CL500 as well as the S63 and CL63 AMG models, which are fitted with Stuttgart’s new V8 bi-turbocharged engines. In addition to the powerplant enhancements, the German tuning firm has also developed a range of cosmetic and handling upgrades.
Starting with the S500 and CL500 models, Brabus offers two different engine tunes for the 4.7-liter twin-turbocharged V8. The first kit includes a new ECU priced at €4,900 (~US$7,160), which bumps output from 435HP and 700Nm to 482HP and 780 Nm (575 lb-ft).
In addition to the software optimization, the second kit (priced at €5,900 or about US$8,630) adds a supplementary intercooler lifting power to 520-horses and 820 Nm (604 lb-ft). When equipped with this package, both the S500 and CL500 reach a top speed of 300 km/h (188 mph) in combination with the Brabus Vmax Unit.
Moving on to the S63 and CL63 AMG models, Brabus’ tuners developed a package that includes an ECU optimization and a water-to-air intercooler powered by an electric auxiliary pump, priced at €5,900 (~ US$8,630). After the conversion, the 5.5-liter BiTurbo V8 produces 584HP (+40HP) in standard form and 620HP (+49HP) and 1,000 Nm (737 lb-ft) of peak torque when equipped with the optional AMG performance package.
The most powerful variants with the 620HP tune complete the 0-100km/h (62mph) in 4.3 seconds and in combination with the Brabus V/max Unit, reach a top speed of 320 km/h (199 mph).
Other available components for the S63 and CL63 AMG include a sport exhaust system with a flap control that allows the driver to adjust the sound of the exhaust, a limited-slip differential with a locking rate of up to 40 percent, and an aero kit with a front spoiler, rear diffuser and carbon trims.
Both the standard and AMG models can also be equipped with Brabus’ alloy wheels ranging in size from 19-to 21-inches, as well as numerous interior refinements.
