Someone in Germany should check the plumbing as the 2012 Mercedes C63 AMG has been leaked for a second time.

In the latest batch of photos, you can see the updated model features an aggressive front fascia, a revised grille, new headlights and LED fog lights. Out back, changes are relatively minor but include a reshaped bumper and revised tail lights.

No interior pictures were released, but the first leak showed the cabin will receive the same updates as the standard model. However, to distinguish the high-performance variant, there are unique touches such as heavy-bolstered sport seats, an AMG steering wheel and piano black trim on the center console.

Under the hood, power continues to be provided by a naturally-aspirated 6.3-liter (6208cc) V8 engine with 451 hp (336 kW / 457 PS) and 443 lb-ft (600 Nm) of torque. While this is a bit disappointing, it is connected to a seven-speed 'SpeedShift' MCT transmission which offers improved fuel efficiency and performance. More specifically, the sedan will accelerate from 0-100 km/h in 4.5 seconds and average 12.0 L/100km (19.6 mpg US). Likewise, the estate rockets from 0-100 km/h in 4.6 seconds and consumes an average of 12.3 L/100km (19.1 mpg US).

A bevy of options will be available - including an AMG Performance Package which increases output to 481 hp (359 kW / 488 PS) and 443 lb-ft (600 Nm) of torque - and full details will likely be announced when the car is officially unveiled at the Geneva Motor Show.
