335is Coupe & Cabriolet / New N55 Specs and Models Excluded

nukezero · 01-11-2010, 12:52 AM

with the power success of the 335i n54 engine... they are downgrading future 3 series to a single turbo...

and with the next M3, they are making it the next inline-6 twin turbo setup. So in that sense, seeing how well the twin turbo n54 performed, they are building/improving upon it and throwing it in the M3... while the 3series gets the shaft with a mildly improved 335i.

from that standpoint, they can't make a triple turbo setup and throw that into the M3...

Well according to the article
335 = 208kw aprox 280bhp downgraded from 225kw
340 new model in between m3 and 335 =268kw aprox 370bhp twin turbo 6
M3 twin turbo 6 = 308kw aprox 420bhp

It would be effectively it wouldn't it - at least it's got four fans?

. I thought you know cars much better than I do. Now, seeing that, that might be what they're going to do with the M1, ie, no boost in high rev - but someone posted another article further, might study that.

Come on people, this is not that complicated- Their 340 is our "iS". The iS keeps the N54 as will the 340i- this has been effectively tuned, the first tuned N55 will be in the M1.

Haven't studied the X5M engine much other than the spec eventhough I have a X5M haha. I haven't really come across many articles on the twin scroll technology on the X5M, but my previous understanding is that it is one "fan", but two separate exhaust chambers hitting different vanes. But from what you are saying sounds like I am wrong...

did you not look at the link I gave you above? The schematics make it very clear.

Actually, you are right and I am wrong

. Just studied the N54, N55 and S63, and there is only one fan in each turboscroll, while I understand some other twinscroll actually have 1 smaller and one larger "fan".

The BMW twinscroll only have 1 fan and the idea is to better managed the exhaust flow. In this case, it would be interesting to see if changing the boost would yield similar results to the N54.

Sorry, posting on iPhone makes it difficult to look at it! When I get to a proper computer will look at it.

There is some conflicting info out on the web. I've read the 135 is going to get the N55 with either a 6speed, or 7 speed DCT.

Is this a mistake? Why would the N55/DCT be offered in the 1 series, and a N54/DCT offered in the 3 series. I imagine this is a typo and no DCT will be offered with the N55 yet?

N55 w/ DCT=135

N54 (tuned) w/ DCT= Z435iS, 335iS

The 135 will be the first N55 w/ DCT-foreshadowing things to come for the 1.

trahsub · 01-11-2010, 11:09 AM

Wow. That seems strange to me that they even bothered with the N54 DCT for the 335s in the US. But I guess it may be like you say to give the 1er the bragging rights of N55/DCT.

MonacoJoe · 01-11-2010, 11:10 AM

i am just more confused by reading all this....

can someone summarize implications?

hmmm.... so they will give N55+DCT to the 1-series before 3-series? ...

Map said something about everything coming out officially on January 22....so it won't be long before we know for certain what's what.

mapezzul, Kudos. Safe to assume all 2011 3-series LCI with DCT will be mated to the N54... be it 335is or 340 badgeing..

I think many will be ordering 35is and then same day ordering a 340 badge from Australia LOL

It seems like BMW just increased the complexity of their product line up ten fold for no apparent reason (maybe this is the HPFP solution?).

I can foresee a lot of n54 vs n55 threads in the future.

Indeed. As far as I'm concerned, BMW keeping the N54 in the more sporty models is admission that the N55 is an inferior engine from an enthusiast and performance perspective, not good news imo that so many models are moving to the n55.

Actually no, it is a life cycle. They design the base motor then uptune it as the life cycle moves along. You will see the N55 outperform the N54 in the future, just right now for economies of scale and the vetted testing of the motor the N55 is at one set level- the N54 did the same thing. The N54 has been upped in the 740s, the BMW Performance Kit and now the "iS" versions. When the N54 launched in 2007 there was only one version.... the same can be said about the N55- and as I have said before the N55 will be tuned and it is currently undergoing engineering and testing in several forms which will should debut in 2011....

Thanks for making it clear. Definitely makes sense the way you described it.

I wonder why they chose to mate the N55 to the DCT in the 1, but they do not offer that combination in the 3? It seems like they should have a 135is with the N54+DCT.

It is interesting that Australia gets the 335is, but called "340i" instead. Will they get a Z4 sDrive40i also?

I suspect that with the F3x, F2x, and the F1x LCI we'll see a X40i as the new mainstream turbocharged 6 designation, probably with an updated N55 or perhaps something even newer yet ("N56"). Then, most likely a X30i turbo-charged 4 cylinder as the base model. And with that - for the US anyway - no more naturally aspirated motors from BMW.
