Water cooling....interesting. Guess that's what they meant by more efficient.
Consistent IAT's probably allows for a little better MPG when you're talking about a F/I 400+HP engine.

It will be a proper "S" just like the X5/X6/M5/M6. From what I heard early on is that we have never seen the engine in this form before- block, head, etc... not saying that it is "all new" but this is a huge revision. That is why I earlier pointed out the oil, its in a different location than the stock N55 (thanks for posting those comparos) Meaning there is a new head, not a reworked base head- can't make that big of a change without recasting. There are also some other changes that are not just for the turbos...

Cool to finally see photos of the engine.
I think BMW needs to tread lightly here. While I am excited to see what the new M3/4 will be capable of, I think BMW may be making a mistake with their engine choice. From the perspective of production and costs, it makes sense for BMW to utilize what is expected to be an updated N55. However, this is not the first time that BMW has utilized a modified version of a 3 series engine to power their M3. The US version of the E36 M3 utilized what was essentially a bored out version of the 2.5L engine that powered the 325. BMW did this to keep production costs down and thus they were able to sell the second generation M3 at a similar price point to the previous E30 M3. The downside was that the US spec E36 M3 received/receives the title of basically being a modified 3 series and not a true M car. largely due to the fact that the US spec E36 does not have a purely BMW Motorsport derived engine. I have a feeling that if the new M3 has an updated/uprated N55, a lot of the critics will be saying the new M3 is just a souped up 3 series. Especially if the new car comes with a BMW Motorsport massaged standard 3 series engine and not a stand alone M unit. Which leads me to the point that the 1M was a stroke a genius from the BMW Marketers. The 1M paved the way for what is now the formula for building M cars. Jason

The days of an overall satisfactory car ownership that includes working on the car are over. I am also not yet sold on the "lighter than the current M3" statement above either. Sure they may figure out how to make 7lbs lighter but who are they kidding.

Thats the beauty of Air/Water setups. Not much size is needed to support massive horsepower levels.
Back in my MR2 days, guys shooting for big power would either to a large trunk mount A/A intercooler, or a MUCH smaller A/W in the engine bay, with a radiator up front for heat exchange. |

Interesting pics! So we know it's a in-line six. Not a V6 as a 3/4's version of the ttv8 M5 engine like some claimed. We can see a large air to water intercooler. Also note how we have two "cold lines" coming out of the a2w intercooler - but only one going in! That must mean TWO turbos. Not three. Unless the other air box on the passenger side is for the electric on demand turbo? ???
Also interesting is the two air filter boxes. This car is a RHD(!) werkstestwagen, just look at the windshield wipers. The shock towers have that spider web look of the F10 M5 EDC shock towers have. I have "heard" BMW have gone with a hybrid marriage of the N54 block(& internals) and used the N55 double vanous head of the N55 - and then worked some M magic on that combo. Perhaps these rumors are true. ? S55 anyone? ![]() I also hear the DCT is all new too for the M3/M4 along with some other drivetrain surprises. ![]()

On a different note, I for one think it's great that this car will be lighter than the E9x. Sure, it'll still be a heavy car relative to a GT3 or Miata but the 4-5seats, proper trunk and all mod-cons give it massive real world practicality advantages. The M3 has been heavily biased towards being jack-of-all-trades vehicle since 1992. What sets it apart is that it is able to hit higher heights of track and fun than its direct rivals. I don't this one will disappoint. For a bigger, stiffer car to weigh less than it's predecessor is a huge step in the right direction, whether it's 200 lbs or 2lbs. |

Able to share more on this? So it's DCTII, in effect? Would that make it similar to the version in the M5. If so, it's rated to well above 500 lb/ft which should please the tuners and be good news for longevity of those who keep things stock....

I don't care if the engine looks like something only a mother would love. That's just aesthetics.
As long as this car performs well on and off the track, i'll be all set with the F80 M3.
