Engine outputs remain the same, with the C63 producing 350kW/650Nm, and the C63 S topping that with 375kW and 700Nm, but other features of the new C63 should make it a sharper performer.
Notably, the AMG C63 now features the 9-speed AMG Speedshift MCT wet-clutch gearbox, which shifts faster and weighs less than a torque converter.
The AMG adaptive damping ‘Ride Control’ system has also been re-tuned and the C63 S now features dynamic engine mounts, which stiffen or relax as different drive modes are selected.
A new AMG steering wheel is found in the cabin, as well as new sports seats which have optional adjustable bolsters, heating, cooling, and neck-heating in the cabriolet variant.
Visually, the C63 gains subtle design changes, such as a redesigned ‘transverse fin’ in the outer air inlets up front, or the altered tailpipe trim at the rear.
Different interior trims are also available, including anthracite open-pore oak wood or walnut, or AMG trim in matt silver fibreglass.
CEO of Mercedes-AMG Tobias Moers says It’s important the C63 remains up to date as one of AMG more popular models.

"The AMG C-Class is our best-selling model series and therefore a key cornerstone of our company's success of recent years," says Moers.
“We have therefore increasingly expanded our C-Class offer: customers can now choose between twelve models from the C-Class family.
“As part of the latest facelift, we have upgraded all variants of the model series even more substantially.
"This relates to the 43-series models and especially, of course, to the AMG C63.
“The perfected driving dynamics and expressive design underscore the powerful, muscular character of the rear-wheel drive icon."
