AMG maybe the Mercedes-Benz in house tuners (as STi is to Subaru, M is to BMW, , but Brabus are the true passionate Mercedes lovers, the ones that extract every little bit of potential from the already powerful AMG models.
Brabus recently announced their B63 S engine tuning kit for all Mercedes 63 AMG owners (6.2-litre V8). Power is lifted to an extraordinary 404 kW (from 378kW) and torque reaches 650 Nm (from 630Nm).
For an CLS 63 AMG owner the tuning pack would cut the 0-100 time from 4.5 seconds to 4.3 seconds (and increase top speed to 330 km/h). In order to achieve the extra power, the cars engine management system as well as exhaust, air intake are all changed. However, the car still meets EURO IV emissions limits!
Brabus tuned Mercs are a rare sight in Australia, so next time you see one, show some respect!
