The automatic is most likely tuned like my x3m and in any profile but the most tame ones it keeps the RPMs pretty high, higher than my F80 ever did. Once going these things never lack power and it's instant. Only lag was right at launch but I think that's gone away now.

The more progressive power delivery is a welcome return to M cars. I've experienced it on the F87 CS and it makes these engines comes to life. It's good to have rewards further up the rev range.

It's what ESS does with their F80 tunes, and tuning boxes.
They lower torque so you don't smoke the tires at each light.

Its is phenomenal tune. ESS rocks and dynoed w tuning box on normal fuel it made 540 on a comp. No other mods.

As others have noted, very much a positive IMO. It addresses one of the biggest complaints of the F80. A more progressive powerband increases control and plantedness of the car, especially on corner exit. This benefit has been reflected in the reviews.

In general this is a trend among newer turbo cars. Initially everyone was focused on max power everywhere, but have realized there are dynamic and enjoyment benefits of a more progressive powerband.

You'll feel the fuel consumption for sure XD

I don't know what that means. I don't photograph well so I've just accepted that I'm not as good looking as I wanted to be 😆

The g80/g82 stomps the M2 CS performance wise.

That's only a problem if you would rather do a burnout rather than actually launch.

They could have avoided that with some clever turbo architecture: twin turbo or electrical assisted turbo.

LOL you mean like an S branded engine is supposed to!? (Linear power that builds to peak power at redline) not this half throttle @ 2500rpm with full torque right now crap that's in the f8x, 335i, 340i, etc.

Define "stomps" if you mean purely straight line acceleration, you're marginally on point. If you mean will smoke it around a track, I think you're dreaming, even with the upcoming 4x4 mode

This has to be the first time in my life that a serious weak point of this magnitude is considered a feature! A torque threshold has nothing to do with progressiveness. BMW considered that they can deliver this engine with this serious flaw, projecting it back 20 years in the past. When reading the positive reactions on this weakness, I have to give it to them that they could probably get away with it.

so you point a characteristic out of every turbocharged engine and call it a BMW weakness?
Imo they did a good job on how the power is delieverd through the band. It doesn't kick in instantly and goes quiet linear to the peak.

So what is exactly NOT good with this engine and power delivery?

Have you driven an early F80? Most complain of "spiky" handling. BMW quickly addressed it by reducing low-end torque early in the F80s lifecycle and it was viewed as a positive by most customers. They carried that learning into this gen.

That's fine if you personally consider it a negative, but it's not a "weakness". The fact is it's an intentional design feature that the majority of people view as positive. You just happen to be in the minority and nothing wrong with that.

Porsche did the same thing with the new 911 btw.

There will probably be an aftermarket tune that will offer that torque curve for people like you.

It... is... a... twin... turbo? Are you trolling? Based on your other replies in this thread I can't be sure

Of course. It's a bigger model with more power. I just like smaller nimbler cars

Koen G - Smoking Tire released their review. They actually discussed this specific improvement.

Go to the 10 min mark. They discuss the improvement made to the torque curve.

Yes indeed, I meant bi-turbo.

100% the G80 comp I drove could actually put its power down where my F80 could get smoked by a Honda Accord if I wasn't being very careful with the throttle. The only weakness is lack of DCT. Everything else is far superior over an F80.

Strange, I never knew a car criticised to reach torque too early. For me, it may already hit in as from idle! I understand that this might be too much to handle in 1st and 2nd gear, but it certainly is not in the higher gears. I definitely have to try it out one of these days!

Agree, but the G80 also improved the entire wheel guidance and set-up inclusive the differential and torque vectoring I presume? So much of this better control is coming from there I presume.

@Imran@Evolve Great video, thanks.

Are you able to post the plots on here? Adding stage 1 S55 would be helpful too if possible please. Boost pressure trace?

As the S58 and S55 have similar specs (bore, stroke, displacement,etc) do you think the S58 is at a higher state of tune than a stock S55, so in essence running a stage 1 tune from the get go, or this engine and turbo has as much headroom as an S55 but starting from an even higher base? Interested in yout thoughts.
