Here we have new new spy shots, showing another C 63 AMG prototype with less disguise on the front bumper, revealing more of the air intakes.
Other typical AMG updates we can see include new rear bumper with air intakes, side skirts, spoiler on the boot lid, bigger alloys, bigger brakes and quad exhaust tips. There is also a new updated AMG specific suspension.
Under the bonnet is most likely a 4.0-litre twin-turbo V8 producing around 450bhp.
There will be AMG versions of the Estate, Coupe and Cabriolet as well, but that will take some time as the standard models are still testing and the first one to debut after the already unveiled saloon variant, is the C-Class Estate.
