Received as a tip from an anonymous reader, this amateur footage shows the Mercedes C63 AMG up close and in action. On three separate occasions, the driver of the test car speeds away which unleashes the beautiful sound of the 6.3 liter V8 engine. The commentary from the videographer is a bit awkward and effusive but somehow funny. We are expecting the C63 AMG to make its debut at the Frankfurt Motor Show this September.
