Brabus Cranks the Mercedes-AMG C63 S Up to 591 HP

More boost means more power for the AMG sedan.

It’s never long between the launch of a new Mercedes-AMG product and tuner Brabus’s announcement of hop-up parts for the car. This time, Brabus engineers have worked on the new Mercedes-AMG C63 S sedan and wagon, boosting the already potent car’s output and fitting it with new visual parts.

Available for the C63 sedan or wagon — and presumably, soon, the new C63 S coupe — the Brabus PowerXtra B40-600 tuning upgrade is a plug-and-play box of electronics that increases turbo boost pressure and modifies fuel-injection timing in the car’s twin-turbo 4.0-liter V-8 engine. Brabus says that with its upgrades fitted, the Mercedes-AMG C63 S will produce 591 hp and 591 lb-ft of torque, up from 503 hp and 516 lb-ft in the standard car. The sprint to 60 mph is said to fall by one-tenth of a second, to 3.8 seconds.

Brabus has also developed a new adaptive stainless-steel exhaust for the Mercedes-AMG C63 S. Like the Roush system we recently sampled on a Ford Mustang, the exhaust has a button that quiets the engine’s output for when you need to keep a lower profile — for instance when coming home late at night.

Other enhancements to the Mercedes-AMG C63 S include new aerodynamic add-ons, 20-inch Brabus-designed wheels, aluminum shift paddles, Alcantara upholstery, illuminated stainless-steel door sill plates, and carbon-fiber mirror covers.

The Brabus-tuned Mercedes-AMG C63 S will make its public debut later this month at the 2015 Frankfurt auto show.
