Took delivery of our C63 only a week or so ago....our first Mercedes, but we've had a succession of other V8 "Toys".....What happens when you "put the pedal to the metal" is very important to me.
Whilst proceeding through the buying process, I was aware of the existance of the new 5.5L twin turbo engine that was appearing in other models.
I was met with the usual....not in the C Series, not for a while, this chassis won't take the torque, won't fit in the engine bay etc etc, from various individuals, & we made our decision to purchase in full knowledge of the fact that a new "Hi-Tec" engine may not be long in replacing the current 6.2V8.
In fact, I prefer the concept of a big, lazy V8, rather than all this new stuff, not that the 6.2 is not "Hi-Tec". I suppose this "preference" could change if the "new" 5.5L twin turbo equipped "C63", was markedly superior to the current model?
So, my question is, how long will the 6.2V8 last, & how long do you think it will be, if ever, before the new engine appears in the C Class?
Cheers, Pickles.

Good question. With the 5.5L TT being rolled out across the range seems inevitable it will end up in the C-class at some point.
Probably many reasons why Mercedes/AMG persisted with the 6.2 litre unit in the updated C63 (probably mostly because they were still "locked" into limited production of the 6.2 litre motor for a few more years), but I would suspect it will only last until the "all new" C series arrives in a few years time. (Remember that the 2012 C series is only a mid cycle update with (mostly) cosmetic changes rather than an all new designed-from-the-ground-up version of the C class).
With the very strict emissions targets etc that Euro manufacturers have to meet the 6.2 litre unit will become a relative liability in a few years time, and with the 5.5litre TT already here the old 6.2's days are numbered I would have thought.

From sources here, we've been told that it might get a revised version of the 4.6TT motor. Lets see what happens.

I love NA engines, period!

I also love NA engines..
But apparently it is too big for the bay so the 4.6 could be more possible.

As the new M3 is also going turbo

I thought I read that the chasi of the C63 wasn't the best for that much power/torque. I think that the C63 would need some serious work in the back like much wider wheels and tires, some proper wide wheel weels, some weight drop,rear LSD and some drop in height. An AWD system will benefit the car a lot if they decide to put a TT engine. My .2c

A proper AMG will NEVER be AWD.

C63newdude

^^^ it is all about marketing. If customers ask for it and AMG wants to listen they might offer it some time. The best sports cars in the world have AWD(Lambos, Porsche,Nissan GTR) and the ones that don't(Vipers, Corvette Z06, ZR1,Ferraris,etc) have a minimum of 295 or 305mm tires and up...
but off course, AMG has to be less than everyone and that is why the number one complaint on a C63 owner is lack of traction.. It makes sense to me

Yuille36

If they were to offer it, the HP would be reduced as with the current model. AMG doesn't want to cut their own throats. Why would someone buy an E63, when they could get the same HP and Torque numbers in their C63. Unless they just wated an E63, but I discovered alot of new owners only want the HP, not the refinement that is a E Class.

I'd buy a AWD C63 in a heartbeat as long as they can keep the weight down.

The 4.6 TT is rated at 402/443 in an E class and could easily be tuned by MB to rev a little higher and be given a couple extra pounds of boost. I would speculate that the W205 C?? will be fitted this way and at a curb weight of about 3700 pounds.

My MB tech friend has been at some courses in Vancouver where there has been mention in training of the 5.5 NA going into the C class. Its currently in the SLK with 420hp. I can see them bumping it up slightly and having the C63 losing some weight.

This is the engine that is currently used in twin turbo applications too. (Minus the turbos obviously)

It follows their past history of using just 1 engine or 1 variant of that engine in most AMG models.

This is what I was gonna say. Cylinder deactivation, other new goodies, AND it'll definitely fit!

jacob502

sais who?
Not true. This baby perfectly fittted the V12 brabus 6.3 engine (in the C-Class Brabus Bullit), which is larger in all angles and dimensions than the 5.5TT

Harold1898

I was told last week by the dealer that they are experiencing strong demand for the new motor and they have not got the manufacturing capacity to fit it to the C series.

justthebest

And Brabus obviously crash tested / mass produced that model...

I'm pretty sure almost anyone on this forum knows more than a dealer. They are usually waaaaaaay down the list re: new product information, much less a production-flow issue like that.

Harold1898

Sorry, I did not realize that. Simply quoted what they told me.

jvanbrecht

There is no need to crash test it, since there were no changes made to the C classes safety framework, so the crash test for the regular C class would be applied.

The only testing they would have to go through are environmental and emissions.

Merc63

I'm not sure where this "chassis can't handle the torque" came from but I find that highly unlikely. The chassis can easily be stiffened in the right areas IF needed. I really doubt it would be the weak point.

Pickles

Guys.....as the O.P.....a major part of my question was "When"?!!
No-one has made a "prediction" with respect to that question.....so, what would you say...2 years?
Cheers, Pickles.

Sincity

Well, as long as the V12 will slide under the cowl/floor like the normal production motors in case of a heavy impact.

Nachtsturm

I read that the Bi Turbo 5.5 was not put into the C63 for cost reasons. It is a much more expensive choice when compared to the 6.2 and would have raised the cost of the C significantly.

antman0505

It would make sense that whatever engine they decide to use would go into the next generation C, given that the current series has only just undergone it's mid-cycle refresh. 2-3 years ?

justthebest

The 5.5 with two turbos will not make it into a C63. The 5.5 N/A as seen in the new SLK AMG will. That's my guess.
