Mercedes-AMG C63 Coupe revealed

Mercedes-AMG C63 S Coupe

Boom! Just like that the Mercedes-AMG C63 coupe is no longer just a C-Class with two less doors.

That’s also the sound of a super-sized gauntlet being thrown toward at a certain BMW M4 rival.

The Affalterbach performance division aims to move from strength to strength and right previous wrongs. If the old C63 coupe was a bit blocky and lacking stance, then AMG has done a fine job of making the new one both swoopier and fatter.

mercedes amg c63 engineWe’ll only get the C63 S in Australia from about the middle of next year, and it gets the same 375kW/700Nm 4.0-litre twin-turbo V8.

But the slightly smaller two-door monsters 100km/h in a claimed 3.9 seconds, a tenth faster than the four-door. There are a few reasons why, and plenty of nerdy devil in the detail comparing C63 S sedan to C63 S coupe.

Compared with regular versions of the new C-Class coupe, mighty wheel arch flares push width of the C63 S out by 66 millimetres at the rear and 64mm at the front. This compares to only 14mm wider front wings on the C63 S sedan compared with C-Class sedan.

Benz says it isn’t just the weight reduction that gets the performance gains over the four-door, but also wider tyres and shorter-legged rear-axle ratios.

Rear rubber width moves up by 20mm to 285mm and front width is up 10mm to a 255mm, each on a 19-inch alloy rim propped by wheel bearings pushed 25mm further out than the sedan, along with stiffer elastokinematic tuning and higher negative camber.

Other than that there aren’t many differences unless you love frameless doors, no middle rear seat and enjoy the subtle black lip spoiler atop a fatter, more horizontally focused rear end.

AMG clearly believes it is even better to drive than the sedan, though – it tags the C63 S coupe as the sportiest C-Class ever. We doubt they’re forgetting the wicked $250K-plus C63 Black Series either.

Expect a circa $165K starting price from mid next year, or about $10K more than the sedan.
