My F80 M3 delivered! Alpine White/Sakhir Orange (exhaust clip, interior, vs E90 M3)

[KKM3]

Going to miss the sound of the old Na m motors.

Faaast! Launch is pretty amazing. But now I'm back to choosing manual; DCT makes it that much easier to get speeding tickets without the visceral thrill. It seems almost too easy, too seamless.

For route counseling, I'm willing to give you tips on hair and blouses. It just might work for you as well as it does for me. I would love to say, this was just humor, but...

As of 30 mins ago I have now agreed a price with my dealer, now just awaiting a colour combo to be decided by me.

The sound is Amazing
If its fake, so what. Open the window and you will hear its beautiful noise.

The mix of boost and spool are just beautiful along with the DCT burp :-)

Yeah that's pretty fast if doing it at that temp, with a passenger, and one run. Best E9x could muster is ~9.5 0-100 mph.

For everyone wanting to see the race with the E90, sorry to be the spoiler but new M3 is going to be quite a bit faster, which has been known for quite a while now.

Consider this was in 95 degree heat. Think about that again. 95 degrees F, in a turbo car. Nice.

UAE247 - my VBOXsport arrived at the office finaly. Connection with the ipad Mini and IOS 7.0.4 works flawless.

I will post data soon. .... oh man - that will become so frustrating

[M3ryder55]

I find it comical how some think the f8x will be slower than the e9x.

Agreed. I doubt it will be slower. That is kind of silly.

Ok guys, here are some very fresh data, while I am still standing on the road, to give you a feeling for the speed of the new M and maybe also the convertible compared to my N55 stock.

My countryroad is about 2400m long, dense bushes right and left...so not much wind to think about. There is a descent of 14m over the 2400m distance. I gathered the data in both directions.

Weather is 14 degrees celsius, 100% sunny, altitude some 150m.

I went to a weightscale before. The 335i Vert is 1880 kg inkl. me, 19" 313 wheels with hankook v12. Tank holds about 30 liters.

I do not know why, but the vbox does not log 0-100, only 0-70 and 0-130.

Results: (I did not use the launch. Only DCT on sport and go)

0-70: 3,99 and 3,92
0-130: 9,45 and 9,32
Top speed after about 2000m: 228,4 and 228,1
The speedometer was showing 240 as topspeed(!)

So much for now:

Vbox did not work at the screen, had to put it to the side window.
The scale was a truckscale. Weight is +- 20kg

If you want to campare to speedovideos:
My speedo is off about +3,5kmh till 100. after the gap widens.
Time to reach top speed was 30,7 and 32,1

Not clear what you are talking about, or which car ?? Are you in the wrong thread? Or do you have a new M3 or M4 ?

If it was me, I will get a manual.
But
I love the DCT and am satisfied with it.
And now, seeing how it launches with no drama I guess DCT.

Thx for the reply. I am confused you answered both i will get 6 MT than DCT !!!!! Its my only car and i dont do much long commute and i dont think ill be launching this car that often. 0-60 times and track times are not that important for me. The only thing i enjoy is DRIVING. i am some what worried about how fast it shift to 2nd as if 1st gear is almost useless. I know a tough question but i think allot of people here want to hear your answer. Thx again.

Lol I was like wtf

[JoeFromPA]

Great video. Very fast car. Don't know why no one else has mentioned it, but it slows down not so much at a specific speed but when it shifts up to 5th. Around 120-130mph.

My point being that it doesn't "die off up top" or anything else. Looks like it was geared a bit less aggressively above ~130mph/5th gear, probably for fuel economy purposes and because it's going to cross the quarter mile right around that mark. And while it's great to hit 150mph on a back stretch of some track, realistically the speed that matters is up to about....125mph

Anyway, not sure why some folks are surprised that a 3.0 liter twin turbo doesn't pull like a 4.4 liter turbo at speeds above 125mph. The m6 is a boat with a sledgehammer engine. Awesome. Jay Leno's Tank Engine Car has over 1600hp now - doesn't make it "better" than the M3 (though it'll still be cooler)

[neverbeentoofast]

no - not the wrong thread. I know there are some people like me, waiting to order the M4 convertible and while doing so, being very interested in some real life data comparing N55/N54 and S55 performance. sadly there is nohting better on the web than this thread at the moment. so: everybody who doesnt care - please dont care!

It also will increase boost to deal with altitude . My S63tu barely lost a mph in trap speed going from a negative 2k density altitude to a positive 1k density altitude day ! It did this by running more boost not less ( data log confirmed )

The boost increase in hot ambient temperatures and high altitudes is normal in order to maintain the same oxygen levels entering the engine (hot air contains less oxygen, high-altitude air contains less oxygen per volume unit). But the ECU can't compensate for high-IAT conditions (which can happen in both low and high temperatures and at all altitudes). In this case, there are tables in the ECU software that specify load target correction factors. For example, the N54 engine ECU has a table called "Load Target Limit Factor" that lowers the load depending on engine oil temperature. If it passes 120C, the loads are reduced to 86% of the normal loads. There are also many other "Cylinder Temp Compensation" tables that lower the load in certain conditions such as high intake air temperatures (intercooler heat soak).

I'm curious as to whether that is the best shift point for all acceleration or just getting to this industry standard benchmark the absolute fastest. I'm curious if the 1/4 mile time would be better, worse, or the same shifting at 7100 or some other point. As for the short shift out of 1st, my guess is that it is more important to stay in the peak torque band (as opposed to higher horsepower) at this point in acceleration because you are really trying to change inertia at a high rate at this point. This is where torque is king.

Who's happy to hear UAE say that his new toy is "much faster" than the E92? I've been hoping to hear that for some time - can't wait to experience it. This may be the perfect car, if it feels like a brute at lower speeds in addition to its high speed finesse and luxury quotient.

According to the BMW published numbers, the power plateau of 431hp extend from 5500 to 7300rpm. To get the best possible acceleration, you want to keep the engine the longest possible in that band. Due to gearing, 2nd to 3rd shift drops the rpm below 5500rpm even when shifted at redline, so a redline shift from 2nd to 3rd will give you the best acceleration.

BTW, horsepower is always king, torque at the crank by itself is meaningless .

We really just all need to finally see this 1/4 mile run.

Because the power starts to drop off after 7300rpm. If more power is available in the next higher gear, than it is better to shift. With the the power plateau starting at 5500rpm, it is best to short shift all gears above 2nd.

You guys can't use a stop watch to measure the speed , for one it's inaccurate and secondly it doesn't take into account the true GPS speed . When his speedo showed the equivalent of 100 mph he was really only doing ~ 96 mph . Let's see what the Vbox data shows . All these rough estimations prove is that F80 is significantly slower than the M5/6 in a straight line as my M6 made it to 130 mph GPS verified speed in 12 seconds vs the M3's ~14.5 sec to a speedo reading of ~130 which in reality will be maybe 125 mph GPS .

The problem with you're line of thought is the IAT never gets that high in the street . I have data logged extensively in SC 90 degree / high humidity heat which is wayyyyy worse than desert conditions and have not seen IATS become more than 120 degrees after 4 consecutive runs in an M6 . I'm sure the intercooler in the S55 is as good as the S63 TU . So on the street high IAT's is not a real problem . On the track that may be a real issue .

Have you set up a Dyno Test yet?

It now sounds we are all splitting hairs here in this thread. Nonetheless, I'm in for all the entertaining reading.
