Mercedes-AMG C63 S Coupe review

Not just a C63 sedan with two less doors

Mercedes-AMG C63 S Coupe

You might imagine this is a very easy review to write. After all, this is just a Mercedes-AMG C63 S sedan with a swoopy new body and two less doors, right?

Not quite. In an effort to greater differentiate the two models, AMG has re-engineered the Coupe to offer more grip and sharper dynamics.

That Kardashian rear end allows the fitment of a new rear axle, with 50mm of extra track, less compromised geometry, uniball joints replacing rubber bushings to improve response and wider rear rubber (now 285mm) to improve traction.

Under the bonnet is the same 375kW/700Nm 4.0-litre V8 as the sedan in all its twin-turbocharged glory, though a slightly shorter final drive ratio makes it a little more eager, AMG claiming 3.9sec from 0-100km/h, a tenth faster than the sedan.

It's an astounding engine, with a soundtrack like you're being chased by a thunderstorm, and it's matched to a much improved version of AMG's seven-speed wet-clutch automatic gearbox.

When the C63 sedan is already so capable, an extra five per cent traction or sharper response isn't really going to be noticeable at road speeds unless you drive the cars back-to-back.

Which isn't to say the Coupe isn't brilliant. The steering is excellent, the balance superb and there's enough traction to go extremely quickly but easily enough power to slide the rear at will, something the Sports ESP setting thankfully permits.

Pricing and equipment levels are yet to be confirmed for Australia, however we'd expect the C63 S Coupe to land at around $160,000 with plenty of equipment standard.
