On that note, the 2016 F30 LCI came in with noticeably improved steering feel. I've had the opportunity to drive every model year of the F30 since it launched with all the steering feel of a Toyota Camry to this latest calibration and I can tell you that it has improved almost year by year up to this latest iteration which is pretty damn good.

This makes me very optimistic for the M2's steering feel as BMW has apparently been hard at work sorting out these electric-assist racks out

I would agree. The fact alone the engine is beefed up/modified and not a tweaked N55, is a victory.

What is strange to me is that cars made in the 90's with EPS get nothing but praise, and yet today they're struggling to get it right.

FR-S will take your stock e30 M3 by one car length at a traffic light though.

I actually wouldn't mind an M2 reduction in horsepower if it were to avoid a surprise gas guzzler tax implementation dated for April 2016.

I test drove an RC-F the other day. I stabbed the throttle and after 2 or 3 seconds, if a police officer was having a bad day; the car would of easily been impounded. I wouldn't be surprised that's the reason why I saw a McLaren in the impound a while ago.

With my old e30 m3 and my current FR-S; I press the petal to the metal for 3 or 4 seconds, I'll only get a slap on the wrist.

Thanks for posting this. I have been saying awhile that electric steering is not the devil- it is an algorithm that Bmw needs to fine tune. Clearly Porsche has figured it pretty damn fine in the Cayman.

And the good thing about it is that an update is a download / flash/ code away.

It is not just as easy as a few lines of code though. Just look at all the extra work that went in to make the M3/M4 steering feel better than the standard cars. Not much is left from the standard steering system.

But of course a software update can do some improvements.

The base F30 328 without sport or Msport or Dynamic package is as bad as the reviews say it is. I was in shock and Couldn't believe I was driving a BMW the first time I had one as a loaner. The suspension wallowing and the dive when cornering are alarming and reminiscent of an old Cadillac

Exactly how I felt about my 235.

I have read many times on this forum and nobody claimed that it is not true. The motor code of the m235i and other n55 are not the same. This is not evidence, but nobody contradicts I thought it was true.
My bad if it is not true


EDIT :
An example :


We can agree that diffrent crank doesn't mean forged crank... Maybe with these numbers it is easier to know if it is forged or not.

Sorry for the off topic...

I would think BMW would have mentioned this fact in their press release for the M235i, which they did not. I would need better confirmation that it is forged on the M235i other than postings by people on this forum.

Thanks for that insight, great to hear that things are improving.

BTW: Do we know if the M2 will get the F8x steering system?

We don't know yet, but it would be a deal breaker for me if it doesn't.

Might be a deal breaker for me too if it does not along with the M4 manual transmission.

Might have to get a stripped M4. But the size...

The M2 is at the top of my list, but if for whatever reason I end up with an F80 instead, I won't be crying myself to sleep. Still have the e36 to play with too.

Still lots of questions to be answered, but we'll get there eventually

Its the exact same thing with people inventing that the N54 was fully forged, which it wasn't at any stage in its lifecycle. No official BMW literature states this. Its all "oh my cousins friends sisters boyfriend knew a guy who tore down his N54 and confirmed it was forged". Why would BMW invest in a fully forged engine that didn't see anything above 350ps from the factory or see use in any other model line? Also why would there be aftermarket forged internal kits being plugged as an upgrade?

Forged crank makes the most sense, and if the N54 had that its not a massive leap to having one in the N55B30O0.

It's well-known that the N54 has a forged crank and rods. Initially, some people said forged pistons, which was debunked many, many years ago. All N54s have cast pistons.

I'd hardly car countless N54 tear downs "my cousins friends sisters boyfriend knew a guy"...

Obviously, BMW realized they over built the engine, hence, they backed it down with the N55, and left the beefier powerplant in the 1M, Z and 335is.

Im not arguing that it didn't contain some forged components, just saying it wasn't fully built. As far as I'm aware, officially, only the crank was ever confirmed. Its not a far fetched concept for the higher output N55s to also be in possession of such (crankshaft). With regards to Iron Mans concern, Yes, different part number does not necessarily mean different manufacturing process, but you never saw BMW marketing making a big deal out of forged stuff in the N54. Even with the S55, they made a bigger deal out of arc-sprayed cylinder walls and closed deck crank case then they did forged internals.

When I read the technical manual on the N55, it says the crank is made from cast iron. When I look at the two different part numbers, the part number for the M235i crank actually weighs 3kg more than the other "standard" part numbers. Why would BMW switch to a forged part and increase the weight? Typically forgings increase strength and allow for weight loss at the same time.

I could be wrong, but maybe they modified the casting design to increase strength and stick with cast iron to beef up the part (without increasing cost dramatically)? I just find it odd that they promote a forged crank on the X4 motor, but make no mention of it on the M235i.

I do agree with you that the single turbo might not be able to generate as much boost efficiently as the twins do in the N54 (remains to be seen) but the soundness of the long block does appear superior on paper.

The twin turbo setup is better than the " twin power " single turbo setup. This is per BMW M engineers. I was told this directly by a BMW M engineer, because I asked the question when the 1M was introduced.


This is why the 1M was twin turbo and the n55 went into to rest of the lineup except the "is limited edition 335/135/z435.

You see that the S55 is twin turbo, the S63 in the X5 and X6M... and M5/M6..the new M6 race motor also is. Etc.

Most of the The high volume models get a single turbo - for better fuel economy, emissions, albeit slightly less potential for power.

LOL . Nor would I expect them to reverse JB4 an S55... in offer to drop it in the M2. :

Well its a good point, but the cast crank in the standard N55 was in turn 3KG lighter than the forged crank in the N54. The 3KG weight increase with the M235i would actually be a good indicator they've moved back to the old forged part? It does seem odd the way they push various things, but perhaps the X4 M40i promotion is ramping up excitement (at least engine wise) for the M2 and how its not going to be a standard N55?

To my knowledge there are no engines with

" twin power " dual turbo setup

"TwinPower" refers to a single twin-scroll turbo with two paths for air flow through the turbo, one shorter and one longer, to accommodate low speed and high speed boost needs.

Twin power single turbo. Yes. No coffee yet and sorry for the typo
