The upcoming 2015 Mercedes-Benz C63 AMG has been spied testing at the Nurburgring both in sedan and estate guises ahead of an eagerly anticipated launch at the Paris Motor Show 2014 in October.
In the following video, the prototypes are quite clearly being tested right to their limits with tire sequel often more audible than the new engine itself!
Under the hood, we know that the 2015 Mercedes-Benz C63 AMG sedan will feature the same 4.0-litre biturbo V8 engine of the Mercedes-AMG GT albeit in a different tune. Currently codenamed M177, the new 4.0-liter twin-turbo V8 is predicted to produce between 480 hp and an incredible 580 hp depending on what specification is ordered. It will then be mated to the 7G-MCT SpeedShift automatic transmission currently used in a selection of other AMG models.
While the new Mercedes-Benz C63 AMG is promising to be an incredible car to drive, there is some concern about how it will sound compared to the brutally loud 6.2-litre V8 powered car currently on sale. It will be interesting to see how Mercedes-Benz gets around this.
Visually, the 2015 Mercedes-Benz C63 AMG Estate will receive the same styling upgrades as the sedan. As a result, we can expect more aggressive bumpers both front and rear as well as a new rear diffuser and quad exhaust pipes.
