W204 C63 AMG Black Series spotted testing again - Sedan and Coupe versions coming?
The C63 Black Series was spotted testing again. As you can see, it is the sedan being tested. Rumor is that there will be two Black Series versions, a coupe and a sedan. What about the motor? Reports are leaning toward the M156 V8 already in the C63 with a higher state of tune around 510 horsepower but the twin turbo M157 V8 is still a possibility. We hope for the latter but there seems to be a split on which motor it will get.
