Loud and fast are 2 descriptive words I'd use to describe this insane AMG. What words come to mind when you view this beast? Start the video at the 1 minute mark to view it in action.

Here are the build specs:

2010 Mercedes-Benz C63 AMG
M156 V8 6.2L engine
ARP head studs
Weistec Stage 3 supercharger system @ 13psi
IAH 2in primary headers, custom intake pipes
Stock fuel pumps, injectors and lines
Rebuilt transmission
Power: 513kW / 688hp @ wheels
Tuned by International Auto Haus
690hp

It threw down a 9.95 at 140.

If mercedes would invest just a sm. percent of what they invest in formula one they could be top contenders in the drag strip circuit.Its almost that their resisting the move due to the common horsepower junky is mostly american tuned manufacturing .In my book it would provide a stable at the meets to showcase the amg marketed named MBs.Auto tuned factory upgraded possibilities are what AMG has to offer ,a good american place to bring the brand.
