The good news continues, by and large, with the C 63 AMG’s chassis, except for one specific problem that we’ll come to. What’s not in doubt is the way this Mercedes steers, the way it stops or the way it handles.
AMG has worked hard to give the C 63 a unique personality and make it feel like a model in its own right dynamically, and the result is hard to argue against.
It has better steering than the M3, we feel, thanks to its crisper response just off centre, specifically when turning in to quicker corners. And the way the chassis loads up so smoothly when you begin to really commit to corners also makes the BMW feel edgier by comparison, particularly in the wet, when the C 63 feels more planted, period, be that at the front or rear, on the way into or out of corners.
We’re also genuinely impressed with the way the car puts its power down so neatly, considering how much power – and torque – there is to deploy.
Of course, it’ll light up its rear tyres if you turn the ESP off and give it a bootful in a low gear (it’ll spin them up in fourth gear on a greasy surface if you’re really going for it), but with the ESP switched to Sport mode the C 63 is remarkably well mannered, even on a wet road, yet also remains sharp and pure in its handling.
And the problem? It’s the ride quality. In the UK, even on 18in wheels, the C 63 feels too stiff on too many road surfaces. On lumpy urban roads at low speeds in particular, it just feels too harsh and too uncomfortable for its own good. We don’t imagine this situation will improve one bit by choosing the sports pack, which brings bigger wheels plus suspension that’s harder still (not to mention composite brakes and a limited-slip differential). So don’t say you haven’t been warned.
