As the all-new 2015 C-Class range begins to enter global showrooms, so too does its high-performance AMG variant draw nearer to a debut. There will be a few fundamental changes, though.
And while these latest photos offer a new look at both the wagon and sedan, this past weekend has also seen Mercedes AMG reveal details of that new twin-turbo engine.
Destined first for the new AMG GT coupe, the new 4.0 litre powerhouse will offer a hefty 375kW and 650Nm in its initial state - and that alone will make it a worthy successor to the outgoing 336kW/600Nm C 63.
The new engine could also help shave a fine layer off the C 63's 0-100km/h time, which, in the current model, is listed at 4.4 seconds.
Benz's familiar 7G Tronic seven-speed automatic will be replaced by a new twin-clutch auto, and AMG's Drive Unit system will alow drivers greater customisability of transmission, engine and suspension settings.
The camouflaged prototypes caputured here gives away few details, but rest assured: despite what appears to be a smooth bonnet AMG's signature twin bonnet strakes will continue to be a hallmark of the C-Class AMG.
These latest shots also offer a more revealing look at the Estate wagon version of the flagship performer, adding a dose of practicality to the powered-up AMG model.
As with the sedan version, the C 63 AMG Estate will get a unique styling kit, larger wheels, huge brakes and a quad exhaust system at the rear.
As for that name, we can expect the C 63 name to stick around - despite the change to a smaller engine.
The C 63 would not be the first AMG model to keep its earlier designation while downsizing its powerplant, with the current SL 63, S 63 and E 63 all powered by the newer 5.5 litre turbocharged V8.
According to reports overseas, insiders at AMG have described the C 63 moniker as simply being "too valuable" to drop.
Watch for official details on both models to surface over the coming months.
