    2011 E9X M3 Performs better than '08?

    I was reading a bit on wikipedia about the M3 and they say that the 2011 M3's may have been "quietly refined" as they performed better than their 2008 - 10 counterparts. Using a DCT, the M3 did 0-60 in 3.9s and 1/4 Mi in 12.4 secs... stock.

    I looked around but couldn't find anything really, and was quite interested to know if anything has been looked at by members who own the cars.

    Plus, does this change tuning at all, and does anyone know if the 0-60 in 3.9 seconds was done using launch control or not?

    That comes from this article here: http://www.caranddriver.com/var/ezfl...af8a28559a.pdf

    There were no improvements that changed the power or performance, whoever wrote that on wikipedia is just going by car and driver numbers. It will dyno and perform exactly the same as all other M3's.

    Don't forget Road and Track got a mid 12@115 mph with a 2008 m3... just magazine times likely done with a Vbox, nothing like on the strip.

    Oh I see... I think you should probably edit that Wiki page then. And I hope there wasn't a thread about this already!

    And why use a Vbox time? And, if there was hp difference, would there be a difference in the 60-130 time too?

    If there was a difference in HP, which there isn't, it would affect the 60-130 time.

    I'm not going to bother with the Wiki page.

    Why use a Vbox? Likely because that is all they had access to.

    I've heard from two separate tuner's (Dinan and ESS) that they are seeing 2011 stock car's dyno higher than previous year vehicles. I asked this question myself after our recent dyno day where two bone stock car's (2009, and 2011) had 7whp difference -- on the same dyno, same gas, DCT, and even the same Density Altitude (259 vs. 260). Here's the two Dyno Database entries.

    Edit: Link directly the graphs.

    This same thing happened on the E46 M3 platform 05+. The result was due to slightly better VE mapping. I'm sure it could be software related.

    Different cars still produce different results. I have seen 2008's dyno as high as 360 whp, I don't buy any difference at the moment based on 1 dyno that with enough repetition we would likely see an opposite example as well.

    It could be but I haven't heard anything like this from any tuners I speak to regarding the E92 M3. Plus, BMW hasn't said anything either on the matter. I think we are reading far too much into a set of results from Car and Driver and people are ignoring that Road and Track even did better with this with a 6 speed M3 in 2008.

    A number of my clients have asked me this same question, and I always tell them that I think this has a bit more to do with variances from car to car than it does with a wholesale improvement on an entire model year. I have seen very large differences in performance from completely stock E9x M3s several times, so I'm not sure that you could really isolate a power increase to be a model year thing, unless you see a trend across a few hundred cars.

    Did anyone think about the fact the 11's have euro filters with no charcoal pretty much like an 08 with a drop in filter (5-6whp on average)

    Nobody did... VERY important point.

    Why the filter change? I didn't even realize it.

    Good point. BTW, your Dynapack entries are finally in the DynoDB.

    Well its a true statement. I never disliked the e9x m3's. As a matter of fact I like them better then the e46 m3's. I think I have even stated I wouldnt mind picking up a 4 door with a dct trans. Wife likes them a good bit. Now if I only swap that trans into my e36.....Click here to enlarge

    No the wife is getting an Audi soon an auto awd. An awesome wife is hard to find, so I'll hang onto her. I also have what I want a turbo'd m3, but that doesnt mean I wouldnt get a e90 m3 sometime down the line. I would like to wait, and see what else gets done with the platform. Usually it takes 5-6 years for many things to get figured out with bmw's and FI. Btw Sticky I'm not really in the know as far as the 4 door/ 2 door difference besides that the 2 door can be had with a carbon fiber roof as standard. Is the suspension pretty much exactly the same on both 2/4 dr cars? Also do many guys have sub frame/diff failures from tracking them. Also whats going on with your car?

    An M3 buddy of mine says the E90 actually has a stiffer frame and tracks better than the E92.

    My car is getting the motor built and details on it will come when the time is right.

    The suspension is the exact same on both.

    No diff or subframe failures, the E92 is strong in the this respect especially when compared to the E36 and E46.

    Some people say that, usually who own E90's. I don't believe it personally, if it was true BMW would have based the GTS on the E90.

    It does seem that way.

    That was true for the E36 M3 -- the sedan frame was stiffer because of the B-pillar (or something, can't remember exactly why). It's not true for the E9x M3. E90 and E92 are supposed to be the same frame.

    Cheers.
