I apologize if this has been covered here; search was inconclusive and this thread (http://f87.bimmerpost.com/forums/sho...&highlight=B58) was nothing but speculation and misinterpretations. Will the M2 get the B58 in the upcoming MY 2018 LCI? BMW has replaced the N55 in most other applications, so it seems likely to me. Having the M240i sit barely below the M2 in the lineup with a fundamentally superior engine seems odd, even for BMW.

My lease is up in May, and there really aren't any BMW models that capture my attention right now. But a M2 with the B58 is about the only thing that could keep me from getting a CPO 991.1.

Scott probably knows by now....

Generally when speculating on future auto updates/changes, I always ask WWTAD (What Would The Accountants Do)?. The B58 is in mass production now, so it must be cheaper than a now-limited-production N55. The B58 looks to be built like a brick house, so I'm sure it can take an extra ~4psi in the M2.

Its been discussed here quite a bit along with the possibility of the S55. I am sure the B58 will find its way into the M2 at some point for the exact reasons that you list but because they are selling M2's with no problems right now we may not see it in 2018. They will have to add power to the B58 to make that change make sense so that means engineering costs and new parts all of which work against the business case in the short term.

This has been beat to death. Plenty of info below.

the LCI will be the M2 CS. as for the normal m2 the only facelift it will get are the led lights nothing else.

Pug is not amused.

I can now definitively state the LCI M2 will receive the LS1 V8 engine from Chevy. Very few people know of this, but my local Pep Boys cashier (Billy Smith) told me. Billy was also only one of three people that knew Donald Trump would win the presidency, so it must be true.

I'm sorry but you are wrong.

"Fundamentally superior engine"? Can you provide references for that? There has been a lot of discussion on this topic, and a lot of back and forth on the details. But that is a pretty strong statement to make with limited data.

The big question to me is whether the B58 can be upgraded to M range performance and retain the smoothness it is being praised for. N55 did it, but it hasn't been proven yet for the B58. Durability similarly has not been proven.

yes it makes sense. the M4 LCI will be the M4 CS too. you guys all just talking bullshit over and over. the M2 wont have any new engine. just the led lights. M2 CS will have the s55 and the CSL too.

N55 has an open deck, so it'll always be limited in terms of boost. B-series engines are closed deck, which is the ideal configuration for aluminum motorsports engines with high boost. Porsche, Subie STi rally racers, etc are all closed deck aluminum engines. There are always compromises; closed deck designs are more expensive and generally require a bigger cooling system.

N->B wasn't just about improving NVH and efficiency; they are fundamentally more robust engines thanks to the move from open->closed deck.

The jury is still out on the M2 and X4 M40i 'deck' discussion, due to lack of conclusive proof and conflicting BMW press releases: see this (lengthy) dedicated thread. Someday someone will open the M2 engine and inform us. Feel free to post in that thread for that discussion. On a personal level, I subscribe to your point of view.

I think we're getting lost in translation here.

My understanding is the LCI will happen next year,possibly Summer and will effectively be the MY 18 model which will incorporate whatever BMW sees fit to keep it fresh such as LED front and rear lights etc,whether or not an engine change is on the cards is open to debate.

The CS is a new model yet to be confirmed by BMW and should hopefully have a different engine ie: S55,' S58' or variant thereof and improvements way beyond what a LCI would involve.

Is this what you mean @ [Levente_CSL] ?

Agree with it being a more robust design, but i believe it was a cost decision rather than an improvement in durability that drove their choice to do this.

The main reason the B engines have a closed deck is because of the modular requirement to share components (including the block) with the diesel engines for cost effectiveness. Diesels see cylinder pressures no petrol engine does hence the requirement for closed deck. Open deck N54s and N55s have put out in excess of 700hp without the block falling to pieces. So its really an on paper benefit as far as series cars go.

The motorsport engines are closed deck anyway and would be even if the series production variant weren't (as seen with the S55). The BXX still have hypereutectic pistons which would give out long before the block would, albeit an 'S' version would remedy this. I don't think we'll be seeing the B58 being any more or less reliable than the N55 unless people push for 1000+ hp builds. Don't think anything in the BMW factory power outputs that would strain either unit above what it can handle.

As pointed out before, please distinguish base M2 and M2 CS + distinguish pre-LCI (MY2016 + MY2017) and LCI (MY2018 onwards):

• The first generation BMW 2er range started production in 2014 (SOP) and production is expected to end in 2021 (EOP);
• BMW 2er LCI (= Life Cycle Impulse = mild facelift) is scheduled for MY2018 (second semester of 2017), thus approximately midway between SOP and EOP;
• F87 M2 started production in 2015 (SOP) and production is expected to end in 2020 (EOP); it is equally expected to adopt the 2er LCI in MY2018;
• The M2 CS has officially not even a 'life', let alone a 'life cycle' or requiring a 'Life Cycle Impulse'; the M2 CS is expected to pop up during MY2018, thus when the BMW 2er range (including the F87 M2) will have gotten its LCI;
• And the M2 CS sporting the S55 engine due for release in MY2018: nil novi sub sole;
• Earlier this year 60 M4 CS were released for the Spanish market (do mind though that "CS" of that M4 CS stands for "Competition Sport" rather than "Clubsport"): comparable to the M4 ZCP though also comes stock with carbon ceramic brakes, a carbon wing on the back and various other carbon-fiber elements.
