Mercedes has officially unveiled the C63 AMG facelift in Geneva.

Drawing inspiration from the SL63 AMG, the C63 has a prominent front splitter, a single-bar grille, and new headlights with LED indicators. Elsewhere, there's a new rear bumper and restyled 18-inch alloy wheels.

Inside, the cabin has been significantly improved thanks to a greater emphasis on material quality. Most notably, there's a new dashboard, a revised instrument cluster, and piano black trim on center console.

As before, power is provided by a naturally-aspirated 6.3-liter (6208cc) V8 engine that develops 451 hp (336 kW / 457 PS) and 443 lb-ft (600 Nm) of torque. It is connected to a new seven-speed 'SpeedShift MCT' transmission that enables the sedan to accelerate from 0-100 km/h in 4.5 seconds (4.6 seconds for the estate) and hit a limited top speed of 250 km/h (155 mph).

For the power hungry, the optional AMG Performance Package increases output to 480 hp (358 kW / 487 PS) and 443 lb-ft (600 Nm) of torque. With the extra power, the dash from 0-100 km/h takes just 4.4 seconds (4.5 seconds for the estate).

Lastly, to improve the car's handling, engineers installed a new steering system, revised spring / damper rates, and a thicker anti-roll bar. Thanks to these modifications, owners can expect "greater driving enjoyment and ride comfort at all times."

The 2012 C63 AMG will start arriving at European dealerships in July and German pricing starts at €71,340.
