Speaking with AMG chief Tobias Moers at the Detroit show, we managed to unearth a few key bits of information about the car.
Straight off, he dashed our vain hopes for a four-cylinder model packing something in the neighborhood of 400 horsepower. "Think about AMG. AMG is a four-cylinder engine company now, and a V-8 company, and I would think that is enough... So it's a V-8."
And it will indeed be rear-wheel drive, not all-wheel drive like the larger 4Matic-only AMG models. In fact, the regular 2015 C-Class will come in rear-drive form as well, in the first half of 2015, in C300 form.
"I think the C-Class is a little bit more fun to drive than the E-Class. The E-Class is more about every day usability," said Moers. "You can have a lot of fun with the car on track with our 4Matic system, but I think the C-Class is more dedicated to fun-to-drive, more sporty, more race track--sometimes a little more sideways. That's the reason it's a rear-wheel drive car."

2012 Mercedes-Benz C63 AMG Black Series
When asked if there is a chance we'll see a Black Series of the next C63 AMG, Moers' response was a hearty and enthusiastic, "Always!" without any hesitation whatsoever. "But, on the longer future, honestly," Moers added, meaning it will likely be a couple of years before it arrives. Why? Because, as Mercedes-Benz USA's Christian Bokich explained, Black Series models are always coupes, so the Black Series has to wait until the standard C-Class Coupe arrives.
For fans of the CLA45 AMG, sadly, four-door coupes might technically qualify as coupes, but AMG won't be building a CLA45 Black Series.
As for what, exactly, will power the next C63 AMG, we didn't get any official confirmation, but we expect AMG's upcoming 4.0-liter V-8 to get the job. Expected power output should easily exceed the 450-horse mark, and despite the downsized engine, we expect the C63 AMG badge to stick--though a rename to C55 has been rumored.
Whatever powers the next C63 AMG, we'll have all of the details in about a year, as that's the timeframe given by Moers for its arrival. Save your pennies, kids. The last C63 was great fun; the next could be amazing.
