2011 Mercedes C63 AMG has leaked to web and it looks more sinister than ever before.

We've already seen the 2011 Mercedes C-Class, but we haven't seen the AMG variant - until now.

Leaked by Germany's EvoCars.de, the picture reveals the facelifted model will feature an aggressive front fascia, a single-bar grille, and new headlights. Inside, the cabin receives the same updates as the standard model but unique touches include heavy-bolstered sport seats, an AMG steering wheel and piano black trim on the center console.

Under the hood, the naturally-aspirated 6.3-liter (6208cc) V8 engine is expected to carryover with 451 hp (336 kW / 457 PS) and 443 lb-ft (600 Nm) of torque. While it is interesting to note the C63 won't use the new 5.5-liter bi-turbo V8, it will eventually be offed in the Black Series coupe.
