As you may remember, back in October we brought you word of Carlsson's foray into the field of Mercedes C63 AMG tuning, with a model they called the CK63 S.  Its figures were impressive – 565 hp/415 kW and 685 Nm of torque, 0-62 mph in 3.8 seconds, and a top speed of 186 mph.  But with any tuning program of this nature, one must beg the question:  "Is it really necessary to add extra power to the already supremely capable Mercedes C63 AMG?"

To find out, Autoblog.nl spent some time with Carlson CK63 S, analyzing both its performance and all around value relative to a standard C63 AMG.  Thankfully, they documented superbly the process, offering both a written review and HD video covering their time with the model. 

While I wont' give too much away, I will say that their overall opinion of the Carlsson CK63 S seemed to be a positive one. To see Autoblog.nl's thoughts on the CK63, check out both their written review and video review.  I've also thrown in a few additional pics of the Carlsson CK63 S below so you can see more of the model in question, should you so desire (click any to enlarge).

Enjoy.
