New engine in 2015 will be TT 5.5L V8 according to Viknesh Vijayenthiran
Heavily disguised prototypes for the next-generation Mercedes-Benz C Class are already out in testing, so it’s not unreasonable to assume engineers are also working on the eventual high-performance AMG variant.
Today we have spy shots of what’s likely to be a test mule for the next C63 AMG, which should join the rest of the new C Class range in showrooms in late 2014 or early the following year.
Though it may look like the current model, a slightly longer wheelbase and wider track confirm that this is no ordinary C63 AMG.
Hidden beneath the sheet metal of this test mule will be the new model’s powertrain, which is expected to switch to AMG’s latest twin-turbocharged 5.5-liter V-8 instead of the current model’s naturally-aspirated 6.2-liter V-8. The smaller engine, which develops up to 571 horsepower in some guises, is not only more powerful than the old 6.2-liter mill, but also produces significantly more low-end torque and is more fuel-efficient to boot.
In the new C63 AMG, expect output to at least match the 457 horsepower of the current model. While fans may be hoping for more power, performance should still be improved thanks to a lighter overall structure. Like the 2013 SL Class, the new C Class will almost certainly benefit from plenty of aluminum--and perhaps some composite--structures in its construction.
2015 Mercedes-Benz C Class spy shotsOf course, a Black Series variant is likely to be launched further down the track to quell the demands of the power-hungry. A coupe variant and possibly a new convertible version will eventually be launched as well.
Drive will be sent strictly to the rear wheels for all models either via a seven-speed automatic or dual-clutch transmission. An AMG DRIVE UNIT will allow owners to modify many of the vehicle’s settings, from the speed of gear shifts to the suspension stiffness.
As we are still in the very early stages of development many of the details may change as we approach the car’s debut in late 2014, so stay tuned for updates.
Thanks, Pickles.

I have posted some comparisons towards the bottom of page 1 on that thread. Hopefully, the info help answer your question.

Put 4Matic on an already porky and fat C63 and the car will lose ALL of its fun. The car is already too heavy IMO. AMG needs to focus on weight REDUCTION to keep this car fun and feeling like a sports car. The next M3 will be lighter than the current one (for a good reason) and AMG would be really putting the C63 behind the competition if the weight increased. 4Matic can only cause the car to weigh more.
MB... please leave the C63 a RWD only car and please shave 300lbs of weight off. THAT would be a fun car. All just IMO

That said, putting the 5.5TT in all of the larger vehicles, and then detuning it for the smaller vehicles, just doesn't make sense again (like they had to do for the C class). Then again, smaller turbos is the easiest way to do it (aside from ECU).
I really do want to see the 5.5NA in the CLA though with AWD....

I have a feeling they are saving the 5.5TT for the upper models and will bring in something else for the C (ie tuned up 4.6TT in the CLS550)
Nobody on the street knows for certain right now
PS....this article was posted 2 weeks ago
I KNEW I wasn't crazy.
Well, I do...a little bit.......I reckon the "new" C63 won't be out for a couple of years, by which time ours will be 3 years old.....so, I'd expect the "new" C63 to be better, but if it was appreciably faster & more powerful, then I'd have to say, that I'd probably be a bit disappointed.
Cheers, Pickles.

Well, except I would shed about 400lb's and make it AWD.
