E9x m3 power delivery
Discussion
So I have come a few turbo cars like a 335i, 330d, Gti golfs and own a vrs estate. I have recently purchased an m3 and I'm just getting used to it and want to pick your brains about the power delivery.
When rolling at say 30mph or even 50mph, 60mph (dct) in drive and the punch it you get a response which is a bit like a roller coaster. Initially you think wow for a bit, then comes another dip in the ride and the car surges im even faster but then it just gets faster and pushes you back more and more
Is this right for d with two bars selected (d2)?
M mode it's just the same but even better, more focused and the power seems more (obviously) yet more aggressive
Is this what everyone experiences?
Also I assume everyone's runs pretty rough first thing. When i say rough I mean more coarse and not as smooth until it warms up abit
Finally I notice that the dct unlike my dsg in the Skoda can be felt at times when it changes fear under full throttle on d2 is this right?
Cheers

I guess my explanation would be better put in that the higher the needle works through the revs the more relentless the power being delivered is. A turbo car is much different offering more in the lower revs... The v8 in the m3 just seems to be the opposite?
You think the power should level off but instead it just gives you more and more urging you not too change gear but instead use all the rev range. My 330i would take an age working round to the rev limit and be not at all as dramatic as the m for obvious reasons.
Just feels different to my previous cars and trying to work out if it's normal

No idea at all, do they benefit from being mapped?
I wouldn't think it has as it's been serviced by the same BMW garage since new and is a one owner. But in reality I have no idea at all as it came from a main dealer
Between 5-7rpm is where it really shines. On previous turbos this is where they kind of flatten out but in the m3 it's just starting to sing

That sound exactly like the power delivery of the M3, It just keeps pulling and pulling and just when you think its must surely be about to fizzle out as there can't possibly be any more, you hit 6k rpm and it is rentless for the next 2.3k rpm.
Totally different delivery compared with a boost engine and in my opinion all the better for it.
The are a bit more coarse when warming up but that only takes a few miles, to be honest I never take it ofver 3k rpm before it hits temperature.

I found with my old V8 M3 that you are just best keeping your foot in and thrashing the life out of it because that is when you really get the rewards and I admit I was left a tad disappointed by the M3 at times but that's because I was used to a 330d and an Audi TTS which deliver their power in a different way.
The V8 M3 relishes revs and rewards the efforts you put in and admitted mine was a manual so you were cog swapping a fair bit to keep it on the boil but the DCT makes this loads easier and it makes a great partner to the high rev motor.

As above, it's just the characteristic of a decent naturally aspirated car. If you look at the power curve it's pretty linear and increases right to the top end.
The down side is a lack of torque low down, but that is what the excellent DCT is for - just change down a gear or two!
It's a very different driving style to turbo cars but I find it way more natural, rewarding and less easy to get bored of.
Also it's nice to trundle around town at circa 1.5k revs
Ref the lumpy start, what fuel do you use? Some e9x are very sensitive to fuel. For example mine runs like a bag of spanners on shell nitro, ok on tesco momentum and seems to really like Sainsbury's super.
If you're running on shell or tesco or BP try a couple of tanks from Sainsbury's and see how you get on.

As has been said the s65 is very linear in its power delivery (a good thing) the torque curve is very flat and you get 80% of available torque across a very wide band.
MDCT is much sportier than he anodyne DSG you're used to, and why are you using d2? Get it into d5 or even better on a dry day S6.
In S6 the car is an animal.

You have to have TC fully off for S6? Or MDM?MDCT is much sportier than he anodyne DSG you're used to, and why are you using d2? Get it into d5 or even better on a dry day S6.

Fully off it then allows you to select S6, I wouldn't be hooning around all day in that setting on a public road as that might be asking for trouble but on a nice dry day a few runs over your favourite well sighted B road is a delight. Welshbeef said:
If you run the car in S6 all the time any mechanical issues as is increased parts wear or that you are simply on it all the time and therefore suffer worse than usual 25.2mpg combined.
That's the great thing about the e92 you can go from d1 to S6 and all the other settings in between and transform the car to suit your mood and/or driving situation. No point in worrying about fuel economy in an m3 as unless you do lots of motorway miles you'll never see 25mpg as an average, nearer 20-22 and the OBC lies as well.

Its not far off 40% better on fuel than my RS6 so relatively frugal!No point in worrying about fuel economy in an m3 as unless you do lots of motorway miles you'll never see 25mpg as an average, nearer 20-22 and the OBC lies as well.

I have an e46 M3 and have owned an e39 M5 in the past, and they are/were the same. All 'M' engines seem to be like this. It's actually a question I wanted to ask about the e92 M3, I was a little curious as I've only driven one that was fully warmed up at the time.Cheers
I like to think of it as 'character'.
From what I understand, this is a characteristic that the M-Division spent huge time and cost ensuring their V8 had. As previously stated, it is (was?) almost a trademark of //M engines, and I personally wouldn't have it any other way
These aren't engines for lazy overtaking, they're proper top end screamers. Even my 20+ year old S38_B38 does all its best work with the little red needle wrapped around the dial, mainly because nobody's told it that it's in a 4-door barge, not a racing car

The entire point of such brilliant power delivery is to allow the (skilled) driver to stay just within the limits of traction as he unwinds the lock past the apex and can have directly and naturally proportional inputs between steering and throttle. Instead of his flow being disturbed by a sudden onslaught of torque that will unsettle a turbo car.
