The spy video above shows the Mercedes-Benz C63 AMG making its usual rounds at the Nurburgring track. Sure, the car displayed power almost the same, or even probably more than the Mercedes-AMG GT, based on several sources. However, the noise expected from the 4.0-liter biturbo V8 engine seemed to be lacking.

One of AMG’s signature is the extra exhaust noise it provides to any Mercedes-Benz its tuners get their hands on. That is something that every buyer and fan of the performance division of Daimler expect. AMG seemed to blow that character off in the upcoming C63 though.

Critics and even the author of this article find the new Mercedes-Benz C63 AMG too quiet for something with a V8 under its hood. Hopefully, third-party tuners would be able to make up for this feature later when they get their hands on the new C63 AMG.

Rumored Specs

As earlier reported, the 4.0-liter biturbo V8 engine of the Mercedes-Benz C63 AMG would have an output somewhere between the range of 456 hp and 503 hp. Despite the expected higher output than the AMG GT, the C63 AMG will not likely outrun the new pure sports car of the three-pointed star’s performance division. The underlying reason for that is the extra weight the C63 AMG has.

Convertible Cameo

One exciting thing to note in the video is a cameo of another C-Class on the works. Pay attention starting on the 0:55 mark of the video. You will notice that a convertible, likely under C-Class, is shown in a couple of seconds.
