It’s called the Mercedes-Benz C55 AMG, but what you’re really looking at is the replacement for the brutal AMG C63 performance sedan.
Mercedes will launch an entirely new C-Class range next year, with the C55 AMG to be class’s performance flagship.
As the name suggests, the C55 will ditch the C63’s 6.3-litre naturally aspirated V8 for a new twin-turbo 5.5-litre V8.
Caught here in testing camouflage, this prototype sedan shows the new car will boast wider bumpers and wheel arches as well as other AMG design touches.
Expect to see more of this car as its testing program progresses.
