After several other tuners have had their say, AMG finally checks in with a horsepower number for the C63: 450. By comparison, the E63 AMG gets 507 hp and takes $83K to become part of the family. The C63 AMG will cost about $20K less, so in order not to offend its bigger brother (and their owners), the AMG V8 has been detuned. That is 20 more than was originally rumored, and 57 less than the E63 AMG. Word is that it will also be differentiated slightly from other AMG's by wearing a mildly restyled bodykit, but will get the quad-pipes to match the rest of the AMG range. The car will be revealed (finally!) at Frankfurt, later this year.
