Well folks, it seems that the AMG stable are gearing up to a full on onslaught to the Brabus folk by sticking the new 6.3 Litre AMG V8 into ALL of their marques with the exception of the A and C class.

This information comes from Jesmb.de. I have been following this site for many years, and it seems that they are correct 99.9% of the time.

It is said that the 6.3 Litre V8 is already producing 500 HP and 600NM of torque - well within the 7G window, meaning that even the S, Cl, SL and E will all be able to get the 7G no problem.

pookie

wow.

Question is when will the 6.3 liter engine be released?

I have my doubts about this engine being put in an SLK for one thing it would take a massive bite out of Sl63? AMG sales. Same engine + less weight = bad move.

If BMW puts a V8 into their Z4, and it has 400+ HP then the 63 in an SLK is much more likley.

The SL65s will still be the flagship - and therein lies another clue. S, CL and SL all have had various types of AMG versions - 55, 63 and 65 (rumours are afoot of 69 models too) why can't other models? Mercedes' marketing is all too aware that if a model exists, then it will sell. You only need to look through this forum to know that.

Also look at it this way, the new 4.6 Litre V8 will bring 360 HP. This is going to replace the 500 series across the range. Then there will be the 550 - a 5.3 Litre na V8 producing 410 HP. (S, SL, CL, and probably CLS and E too). Again, much more than the NA 55s at the moment. I can't see AMG letting a standard Mercedes approach them in power. This is one of the reasons why the 65 models were produced in the first place.

Don't expect the 63 engine in an SLK before 2006. I would imagine that current buyers would be mighty p****d off if a sparkley new SLK55 was trounced shortly after it's introduction.

My guess is that they will tip up after the mid-life face-lift.

It's amazing to see where they're taking these engines.

Would there ever be a possibility of Mercedes making a standard 700 class? Ex: S700, SL700, CL700 ?

And general question: Why are we not seeing 'any' V10's from Mercedes?

mkoesel

I agree.

It seems to me that a much more likely choice for the SLK (and C and CLK, for that matter) the new 5.5L DOHC which will make about 410hp. In fact the C could even get away with the 4.6L DOHC at 360hp. That would leave the 6.3L for the E, CLS, SL, S, and CL (and I suppose the M, R, and G as well).

Of course the SL, S and CL will also continue with 600+ hp AMG V12s as well.

But there would definitely be a C XX AMG, it would be stupid if Mercedes makes no more AMG C-Class. Question is, what engine is it going to use? I'm thinking the same 6.3L engine but in a detuned form, which makes somewhere around 440hp.

mkoesel

Absolutely. I never said differently. What I did speculate was that Mercedes would use the 5.5L V8 instead of the 6.3L in the AMG model. This would be exactly analagous to what they did with the old C43.

Notice this thread is over two years old (before most people would even accept that Mercedes was poised to replace the supercharged 5.4L motor with a naturally aspirated one). Since then it became known that the 6.3L was its own engine architecture, designed from ground up by AMG. It is their baby. Knowing this now, I of course, doubt AMG would forsake it and use the non-AMG 5.5L Mercedes DOHC V8 instead.

Could be. Probably the biggest clue is that the CLK did indeed get the 6.3L, although in slightly detuned 475hp guise. Maybe a similar fate is in store for the C Class and SLK? We will soon know.

Oh yes defintely, there will be a C63 and SLK63 (2008) for sure, only question is how much power. I didn't think a CLK would get 475 hp so anything is possible. I can't imagine a C/SLK with 475hp though, more like 440 like others have stated.

Just FYI
The C63 will be sold with the new W204 (sedan) end of 2007 in Europe. A SLK63 is not planned - not even in 2008.

cheers,

How do you know that about the SLK63?

Wasn't AMG working on a Twin Turbo variant of the 6.3 Litre for the S SL and CL Classes?

Bulge bonnet is housing the AMG 6.3 V8. Also, the old SLR-look on 55 AMG will change to flat bonnet.
Apart the look, the performance is awesome, with massive torque natural aspirated. It is a beast!

nishi

awwwwwwww man, *******s! i thought buying an SLK AMG i'd have the newest SLK AMG there is. god damnit

shahedC

So will the regular SLK will have the SLR-hood? Or by bulge-bonnet, are you referring to a different kind of bulge?

I am getting the 2007 SLK350, so I don't want the SLR-hood to disappear so quickly !!!

Here is a German web page with some info:

I think the look is awesome too. What or who is bulge bonnet? And is that 6.3 V8 detuned or is it the full 500+hp?

Germancar1

There is no SLK63 yet at least not until the 2008 model year, no official info has been released. I seriously doubt MB will back away from the mini-SLR look of the SLK to create a mini-SL, bit mistake IMO.
