AMG brought a thinly covered near-production prototype of the C63 earlier this year at the Goodwood Festival of Speed and now it's about to unveil the sports sedan. There's little we don't know about the BMW M3 rival, although we are curious to find out how those interesting technical specifications will translate into real-world performance. Unlike its rear-wheel-drive predecessor, the next generation will be sold exclusively with 4Matic.
