All of the pages, except for the AMG Edition 1, which is pictured here, have now been taken down from Mercedes-Benz' German site. Prior to that, though, WorldCarFans and AutoBlog Serbia were able to glean the following details about the AMG fettled version of the new C-Class.
Under the bonnet of the C63 AMG is a twin-turbocharged 4.0-litre V8 churning out 350kW of power and 650Nm of torque, which is 10kW and 50Nm more than what the same engine produces in the new entry-level Mercedes-AMG GT. The new car also eclipses the output of the outgoing model's 336kW/600Nm 6.2-litre V8.
According to Mercedes, that's good enough to propel the 1640-kilogram C63 from 0-100km/h in 4.2 seconds and onwards to an electronically limited top speed of 250km/h.
The car rides on a sports suspension package that has three-stage adjustable dampers, while ventilated and drilled 360mm discs at the front and 330mm discs at the rear are responsible for bringing the whole thing to a halt.
Car spotters will be able to pick the C63 AMG out from its lesser brethren by its reworked grille, 18-inch alloy wheels, more aggressive bumpers, aero side skirts, rear diffuser and quad exhaust tips.
On the inside there's a flat-bottomed steering wheel, new instrument cluster, illuminated sill plates, and seats that are trimmed in a mixture of leather and microfibre.
As has become the norm at AMG, there will also be a more powerful S model. The 1655kg C63 S AMG boasts a more powerful 375kW/700Nm version of the 4.0-litre twin-turbo V8; that's the same amount of power, but 50Nm more torque than the Mercedes-AMG GT S.
The extra mumbo helps to shave 0.1sec from the 0-100km/h time, bringing it down to 4.1sec; top speed is still limited to 250km/h.
Aside from the engine, the S model also features 19-inch alloys, glossy black accents on the front bumper, an electronic locking rear differential, dynamic engine mounts, and uprated front and rear axles.
Oddly, the Mercedes-Benz Germany website still features info about and photos of the new C63 S AMG Edition 1.
It's unknown if the limited edition Edition 1 will be available in regular C63 AMG trim.
The Edition 1's main features seem to be largely cosmetic in nature, with the key visual changes being grey door stripes, a high gloss black lip spoiler, and red highlights for the grille, 19-inch alloy wheels and wing mirrors.
The all-new Mercedes-Benz C63 AMG is set to arrive in Australian showrooms in 2015.
