The new model is called the Brabus 850 6.0 Biturbo, and that last word hints at something of a new direction for the performance tuner.
Well-known for its V12 engine-preference, Brabus has chosen a V8 power plant equipped with two turbochargers in the model destined to replace its 800 E V12.
The engine is bored-out from 5.5 to 5.9 litres, and the resulting power will see the ‘regular’ E 63’s top speed improve to between 300 and somewhere beyond 350km/h, depending on various components.
The 850 6.0 Biturbo will reach 100km/h from rest in 3.7 seconds, unless you opt for the 4MATIC all-wheel-drive version, which will reach the same speed in just 3.1 seconds.
Combined fuel consumption is listed at a not-too-shabby 10.3 l/100km.
While 1450Nm of torque is produced by the engine, Brabus has limited the output to 1150Nm to reduce stress on drive-train components, including the standard seven-speed automatic transmission.
The exterior is adorned with an aerodynamic enhancement kit, 20-inch Monoblock wheels and high-performance tyres.
Inside, the 850 6.0 gets leather trim in your choice of colour, aluminium shift paddles, sports pedals and a switchable exhaust system with two settings; ‘coming home’ (quiet), or ‘sport’ (not-so-quiet).
If the 625kW version sounds like a bit much, Brabus offers three more versions of the E 63 AMG with 456, 478 or 537kW, all of which retain the original 5.5 litre engine capacity.
