Mercedes-Benz C63 AMG by Brabus
Top speed is raised to 197mph (315km/h), 0-to-62mph (100km/h) times are cut by 0.4 seconds over stock to 4.1 seconds, and the dash to 124mph (200km/h) takes just 13.1 seconds, a full 1.4 seconds less than the standard C63 AMG. A wide range of other tuning features are offered to go along with the engine upgrades. Custom 19in wheels, performance tires, a limited-slip rear different and a height-adjustable coil-over suspension are just part of the list of possible additions. Upgraded six-piston brake calipers that grab 380mm front and 360mm rear brake discs bring the powerful sedan to a stop with ease, while the wide and sticky Pirelli or Yokohama tires provide ample grip in every situation except pedal-mashing acceleration.
Extracting the extra power from the engine is done via retuning the ECU and replacing the stock catalytic converters with high-flow units. The end result is a gain of 73hp (54kW) and 37lb-ft (50Nm) of torque to end up at 530hp (390kW) and 479lb-ft (650Nm). RENNtech's similarly-tuned C63 AMG reaches a slightly more lofty 548hp (408kW) and 510lb-ft of torque (750Nm), and adds a host of track-focused modifications, most of which are echoed in the Brabus package.
Customer-specific interiors are also part of the Brabus tuning process, with each one done individually by the company's in-house upholstery shop. Key materials include Brabus' Mastik leather and the ever-present Alcantara. Other interior tweaks include Brabus-branded scuff plates and race-style shifter.
