2015 Mercedes-Benz C63 AMG Sedan And Wagon Spied Testing

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. 

The current C 63 AMG is the one of the last road cars to use AMG's 6.2 litre naturally-aspirated V8, and its replacement will follow other AMG models by moving down to a new 4.0 litre turbo V8. 

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.
