The beauty of speculation. Nothing is confirmed until it's confirmed

So, I've heard the same regarding limited production numbers from workers at the Spartanburg Performance Center, so this information is being communicated internally at BMW.

Thanks for sharing.

I can't wait to pick up my limited edition 1/10,000!! Seriously though, I imagine the limit is being set because the 1M being a limited production car made it an instant classic (granted that was a MUCH more limited production). And it was also an excuse to let the 1M encroach on the M3's territory. Another tick mark in favor of a de-tuned S55!

Limited global production run to 10,000 units
No CF roof
Variant of S55 engine

There were some more details on the source's experience with the car, but can't really comment at this point.

Guys, FWIW I think Doc's source was legit and I am moving from the optimistic 'S55 variant' camp to the, it seems like we are getting an 'S55 variant' camp. Then I am speculating that 'S55 variant' means an S55 block with a FMIC (per test mule photos) instead of the M3/M4 water-to-air intercooler for cost savings and as a means of protecting the M3/M4. The question is are we getting 1 or 2 turbos? I think 2 would make since just to minimize re-engineering efforts.

I was also going to mention that though October doesn't match with the earlier North America dealer information, perhaps ROW production starts in October. Food for thought.

Maybe SCOTT26 would like to shed some light on this situation?....

[Doctor///M]

SCOTT26 you were summoned (again)

[Zoli007]

One way or the other this car seems like it will hold its value much better than an F80 M3. Super excited to finally see it!

He's too busy in China sipping some tea. He'll be back with some specially flavored Kool Aid for you, after he's done at the Shanghai Auto Show.

Other than the E30 M3 and E46 CSL, the M3 isn't a car to consider based on value retention. Maybe a low mileage E9X will be a future classic, simply because of the NA V8.

I like the F80 because it gives me 4 doors in a fantastic package you can't find elsewhere.

It makes sense that it will be a TT variant of the s55 because so far all modern turbo M's have been TT only, n54, s55, s63 etc. And the main reason bmw uses the twinscroll single turbo on non m models is for fuel effiency. But from watching all the mule videos it does sound like a single turbo motor to me because of the deeper cleaner tone usually associated with the longer single turbo manifold vs a more raspy higher tone associated with shorter twin manifolds but that's just what it sounds like to me from the vids.

Thanks for your input and great first post! Has anyone else done a sound comparison and care to share your thoughts?

[loxxrider]

I was going to mention it earlier but decided not to since it's already being discussed in another thread, but since you asked...

To me all of the videos from the ring sound like a "N" based engine. They sound nothing like the S55. As stated, that could just be a result of a different exhaust manifold configuration, or even just a change in cam profile!

Listen to some videos of N54 and N55 and S55. The M2 ring videos are almost exactly like an N55 or N54. What is it really that makes the S55 so fundamentally different from the N55 anyway? What really makes an M engine? You could argue an S62 is just a hitter up M60... Same for e36 S engines and even the e46's S54. It's quite different from the M54, but they share the same basic architecture. So what really makes the difference between the letters M and S? Does it really matter what it says on paper? As long as it performs, they can call it whatever they want

I wonder what the criteria is for the S designation.

[W///]

Here's why I'm so skeptical about the S55 info.
1) It sounds nothing like the M3/4, but much more like an M235i
2) We don't see the same cooling setup as an M3/4.
3) Until people can provide info like this, I'd much rather trust this source than others. Granted he did say Auto rather than DCT, but the overall depth of the information is just more credible to me:
http://f30.bimmerpost.com/forums/sho....php?t=1008378

While that info probably isn't 100% correct, that's just way too much info for someone to just make up out of thin air, and getting it correct (and across the entire BMW range I may add).

As for CF roof, we would have seen a camo'ed one by now. You don't just slap on a completely different process half a year before SOP without seeing any signs of it. Look at M3/4/6 mules for reference.

Valid points all around, thanks. BMW, please end my confusion!

This is the one part that gets me as well

[Steven1077]

I thought BMW said from the start it was going to be an N55+? Why fit an S55 when an N55 can easily put out the numbers they’re talking about? It would just add to the cost

[phoenixbmwlife]

Where is Scott? We need answers please

[UpNcOmINg!]

As I have mentioned before, I doubt there will be much between the S55 and the N55 we will most likely see in the ///M2
From the S55 I think we will get;
Forged crank
Pistons
High Pressure Fuel Pump
Spark Plugs
The top end on the N55 is brilliant, even from the e-series times.
I am still hoping that the exhaust isn't yet tuned as per ///M standards and that there is a twin-turbo setup laying under that hood, even though I agree it does sound rather singe turbo. The size of the single turbo doesn't carry torque and power through as the twin does, so I'm really hoping we see the twin setup. If that is the case, we will get the S55 crank case too which will be the closed deck variant.

My feeling, though, is that we will see a new single turbo development for the ///M2 that won't be quite as rev happy as the ///M3/4

[SCOTT26]

Can I get a...

^^^No S55 then.

I think we all have been hoping for an S55 but knew in the bottom of our little hearts that it would be an N55...

I'm not sure how much it matters at this point. The F8X S55 is an N55 at heart. Those who want more power will get more power from it, and the car should have a fully capable cooling unit or the stock setup. Either way, it's going to be one heck of a car!
