Mercedes has quietly released pictures and specifications for the upcoming C63 AMG and C63 AMG S.

First up, the C63 AMG has an aggressive body kit that includes sportier bumpers, aerodynamic side skirts and a rear diffuser which is flanked by a four-tailpipe sports exhaust system.  The car also has a power-dome hood, an AMG-branded grille and 18-inch lightweight alloy wheels.

The sporty styling continues in the cabin as the model boasts leather / microfiber sport seats, a flat-bottomed steering wheel and stainless steel pedals.  Drivers will also find themselves surrounded by an ARTICO-wrapped dashboard, aluminum trim and a black headliner.  Other notable highlights include an AMG-specific instrument cluster, illuminated front door sill plates and AMG-branded floor mats.

Power is provided by a twin-turbo 4.0-liter V8 engine that develops 475 PS (350 kW) and 650 Nm (479 lb-ft) of torque.  It is connected to a seven-speed AMG Speedshift transmission which enables the sedan to rocket from 0-100 km/h in 4.2 seconds, before hitting an electronically limited top speed of 250 km/h (155 mph).

Speaking of performance, the C63 AMG is equipped with an AMG RIDE CONTROL sports suspension with three-stage adjustable dampers.  The car also has an AMG speed-sensitive sports steering system and internally ventilated and perforated brake discs that measure 360mm front / 330mm rear.

The C63 AMG S kicks things up a notch as it has high gloss black accents and black flics on the front bumper.  The model also gains composite brakes and 19-inch lightweight alloy wheels.  The high-performance variant also has dynamic engine mounts, an electronic locking rear differential and revised front and rear axles.

Under the hood, there's a twin-turbo 4.0-liter V8 engine that develops 510 PS (375 kW) and 700 Nm (516 lb-ft) of torque.  Thanks to the extra oomph, the C63 AMG S runs from 0-100 km/h in 4.1 seconds before topping out at an electronically limited top speed of 250 km/h (155 mph).
