We saw the AMG Sport models joining the C-Class line in Detroit, but Mercedes has waited until the press launch of the Mercedes-AMG C63 to give us the details. In case you've forgotten about how this new puzzle piece fits, there's Mercedes-Benz, there's Mercedes-AMG, then there's the Mercedes-Benz AMG Sport line slotted in between for those who want sporty luxury but not too much of either. This is the second variant in that line-up, and also the second to get V6 power, following the GLE450 AMG Coupe.

In the case of the C450 AMG 4Matic, that means a twin-turbo six-cylinder with 367 horsepower and 383 pound-feet of torque, an increase of 38 hp and 29 lb-ft over the C400 4Matic on which it's based. It goes much closer to proper AMG territory with its looks and features, with that sharp, chrome-trimmed lip in front, the oblong lower intakes, lightweight wheels, and a "special AMG badge" on the front fenders. In back, the sedan gets a spoiler on the trunk, the wagon gets a roof spoiler.

There's a suspension highly derivative of that on the C63 AMG, with three-stage dampers. So too the five drive modes laid out like on traditional AMGs, the 7G-Tronic automatic transmission, the ESP with Curve Dynamic Assist, and it will even sound close to an Affalterbach special thanks to a sports exhaust. Cabin occupants can play the real deal with sport seats and a flat-bottomed wheel with red cross-stitching.

We don't have a price yet, but there will probably be plenty of room between the price of the AMG C63 and the $48,950 C400 4Matic to make buyers happy. The press release below has all the info.
