Brabus has revealed its latest aftermarket program dubbed the B63S–700 Widestar designed for the Mercedes-Benz ML63 AMG and GL63 AMG. At the heart of the program is a performance kit that takes the 5.5-liter twin-turbo V8 to 700 horsepower and 708 lb-ft of electronically-limited torque, achieved by using Brabus Gold Heat Reflection insulation, two custom turbos with a larger compressor unit, a remapped ECU, a free-flow metal catalyst system with 75 mm wide downpipes, and a stainless-steel sport exhaust.

The ML63 and GL63 can now sprint from 0-62 mph in 4.4 and 4.6 seconds, respectively, while top speed is limited to 186 mph. All that power and speed is balanced by aerodynamic and chassis mods in the form of a Widestar widebody kit consisting of front and rear spoilers, add-on components for the side air inlets, and a central rear diffuser that can be combined with two ceramic-coated dual tailpipes. New fender flares add 6 cm to the M63's width and 8cm to the GL AMG, which make room for the 23-inch "Platinum Edition" Monoblock R alloys, while an air suspension lowers the cars' ride height. Rounding off the package is a custom interior that can be trimmed in leather, Alcantara, and carbon fiber.
