Powered by that glorious 5.5 L V8 biturbo engine, developing 410 kW (557 hp) and 760 Nm in standard form, Brabus adds a pair of larger turbochargers, remaps the injection and ignition and increases boost pressure, and fits a stainless steel exhaust system with integrated butterfly valve and a free-flow metal catalyst, resulting in 515 kW (700 hp) and a limited torque figure of 960 Nm. Those changes mean the ML hits 100 km/h in just 4.4 seconds, with the GL taking 4.6s, while their top speeds are electronically limited to 300 km/h (174 mph). Sensibly, there is also a brake upgrade using cross-drilled 405 x 34 mm front discs and 380 x 34 mm rears gripped by six and four-piston fixed calipers.
Visually the Widestar body package comprises of an aggressive front fascia with large intakes, wheel arch extensions adding 6 cm to the width of the M-Class and 8 cm to the G-Class, a roof spoiler and diffuser with ceramic-coated tailpipes. Brabus offers a large choice of wheel styles in sizes ranging from 21 upto the 23-inch Monoblock E evo, F and R items, while its electronic module lowers the GL-Class air suspension by 30 mm.
Moving to the cabin, Brabus can reupholster the interior to suit any specific requirements, using materials including leather Alcantara, wood and carbon fibre, along with aluminum components such as pedals, door pins, longer shift paddles and illuminated sill plates.
