AMG confirmed the horsepower rating of the new C63 AMG today: 450. Its larrger sibling, the E63 AMG powers up 507hp, a difference of 57hp. While the E63 is priced at $83K, the new C63 should cost about $20K less. Autoblog is reporting that the C63 will differentiate a little from the rest of its brothers and receive a restyled body kit. Also, it will receive the quad-exhaust pipes, found throughout the AMG line-p instead of the C. The new C AMG will debut at the Frankfurt International Autoshow in September.[Source: Autoblog]
