I'm OT with this, but has anyone come across the M137 E63 AMG from 2001? I understand this V12 was only produced for one month and dropped into very few cars.

Afaik that engine was used in the W463, the W220 and the C215. And also in the W220 Pullman.

LOL, thanks to whomever hived this off into its own thread :-). Just one correction with the title; E63 was the AMG engine designation, not the M-B car model. Curious if any made it across the pond as I believe it was Europe-only?

I testdrove a C215 CL 63 AMG twice. Back in 2002 and 2003. Up to 290 km/h. Which is 180 mph.

Great car at that time. And still. Very exclusive.

Is the new thread title any better, Dean? I can tweak it to whatever you like...

I have never heard of any AMG version of the 137, which doesn't mean they didn't exist, but I'd be surprised if they did a displacement increase on one, as it is one tightly packed engine inside. We were told that the cylinders were at their limit of thinness at 5.8L, and the fact that the displacement was reduced to 5.5L for the turbo versions seems to indicate that to be true. The bedplate bottom end is massively substantial, and I remembered thinking the first time I saw one "this thing is getting turbos or something one day". There doesn't seem to be any room in there to do anything much. If this AMG M137 engine was super exclusive and abandoned, maybe there were good reasons(?) Who knows?

The talk at the time was that there was no V12 envisioned for the 220/215, then the market reacted poorly to that, and they decided that they needed one. The 220/215 front shells were finalized, so the new V12 had to be compact. And damn, it is just that. Fortunately, it isn't hard to work on at all, but it is very compact inside and out...

Standard M137 bore 84. Stroke 87 mm.

AMG did 84,5 x 93. http://tuninghistory.com/blog/amg/834.html

And Brabus pushed it a bit further. As always.:agree:

85 x 97 mm. And in two versions. 450 PS and 475 PS.

So what do you mean at their limit of thinness at 5.8L. :?
I am not talking about durability.

I am not talking about durability.

The implication to us seemed to be that it was about long-term durability, cylinder distortion, etc. In the same class that we were told that, it was additionally pointed out to us that it was critical to not over torque the transmission attachment bolts at the engine, as it could distort the rear cylinders. In its own way, that is common sense for any engine, but this was the first time I had ever heard anything like that clearly and directly stated. So I found this discussion of tuned M137 engines interesting, given that background. Indeed, back when these engines were current, one of the discussion points if one developed an oil consumption issue, particularly if extra oil was entering the rear cylinders was to loosen and then correctly and evenly retorque the transmission attachment bolts, especially if the transmission had been removed and reinstalled before the issue developed. Thanks for the links!

While we are talking about decendants of the M137, let's not forget the M158!!
