If there’s something that Mercedes-AMG’s new 503hp (510PS) C63 S sports sedan and Wagon don’t seem to lack, it’s power, but the tuning minds at Brabus beg to differ.

The Germans have worked their magic on the range-topper C63 S’s 4.0-liter bi-turbo V8 updating it with newly developed turbochargers featuring a larger compressor unit, a special core assembly with reinforced axial bearings, a reprogrammed ECU and a sports stainless-steel exhaust with actively controlled butterfly valves.

That’s enough for the Brabus C63 S to offer 650PS (641hp) and 820Nm (604 lb-ft) of peak torque, up by 140PS (138hp) and 120Nm (88 lb-ft) over the stock model, allowing the sedan to hit 100km/h (62mph) in 3.7 sec (Estate: 3.8 sec)and top out at 320km/h (200mph), an improvement of 0.3 sec and 70km/h (43mph – mainly thanks to the removal of the speed limiter) respectively.

Brabus worked with technology partner Bilstein to develop a specially tuned height-adjustable coilover suspension that allows the rebound and compression rates of the gas-pressure shocks at the front and rear axle to dialed to one of ten settings.

Customers can choose from two different 20-inch wheel designs shod in Continental, Pirelli or YOKOHAMA tires of sizes 255/30 ZR 20 at the front and up to 275/30 ZR 20 on the rear axle.

There’s a carbon fiber aerodynamic and styling kit available in both matte and mirror-polished sealed surfaces that include a front apron, rear spoiler, rear diffuser and mirror caps, with Brabus also offering plenty of interior customization options such as unique upholstery and aluminum trims and accents.

The new Brabus C63S will have its world premiere at the Geneva Motor Show next week.
