Premiering at the Geneva Motor Show next week will be the latest tuning program from Brabus – the B63S for the Mercedes CLS63 AMG. This will be in addition to the SL65 AMG Brabus 800 that will be on display in Geneva.

Under the hood is a 5.5-liter eight-cylinder Biturbo engine capable of outputting 537 kW / 730 hp  and 1,065 Nm of torque, enough to propel you to a top speed up to 217 mph.  How’d they do it?  Brabus developed the program using state of the art bench technology to design two special Braubs turbochargers with larger compressor units, both of which generate a higher boost pressure than the production turbos.

Additionally, a low-temp water to air intercooler in conjunction with the Brabus Gold Heat Reflection system all serve to improve the power yield because of the lower charge-air temps, improving durability as well.  Brabus also remapped the ECU and added 75 millimeter wide downpipes, all topped off with a stainless steel sport exhaust system.

Put all these pieces together, and the Brabus B63S is a monster, capable of accelerating 0-62 mph in 3.8 seconds and 0-124 mph in only 10.8 seconds.  And while the stock CLS is electronically limited to a mere 155 mph, the Brabus B63S has a top speed of 217 mph. Due to the higher rear-axle load of the CLS 63 AMG Shooting Brake however, the top speed for the shooting brake is limited to 186 mph (out of consideration for the tires).

Matching the performance, the exterior of the B63S has been redefined with sporty fender attachments with backlit BRABUS logo and components that are all manufactured from especially light yet high-strength carbon fibers.  Two finishes are available – matte or high gloss.

Monoblock wheels with diameters of 19 and 20 inches are available, with the largest tires supplied for the 20-inch alloys in size 255/30 ZR 20 for the 9Jx20 wheels on the front axle and in size 295/25 ZR 20 for the 10.5Jx20 wheels in the rear.

Inside, the custom-tailored Brabus interior notes extensive use of  Mastik leather and Alcantara. Rounding off the interior is a speedometer with 250 mph dial and rear-seat tables attached to the backs of the front seats; aluminum components such as pedal pads, door lock pins and shift paddles for the steering wheel; and your choice of either carbon fiber or wood trim(s).

If all of these upgrades aren’t enough, you can also opt for the custom-tailored BRABUS multimedia concept – including optional Apple iPad integration and a host of technology features.
