M235i can be banged off the limiter with out auto upshift in sport+ mode so the M2 should be no different.

Two different transmission architectures, so they may be different.

DCT should let you do what you want, doubt it's been nannied fir the M2. No evidence of course but can't see why.

Hi everyone. Great thread - couple of advantages I haven't seen mentioned though for the DCT, particularly for track day usage:

1. Upshifts: I too, have been a manual guy for many years. My SpecE36 track car has a data acquisition and I've got stacks of data showing that every upshift under power costs me about 450mS. The DCT should be <200mS in sequential mode. This adds up during the half dozen upshifts at my home track, and most others I go to. The DCT car should, in this example may well be a second faster. I like this

2. Downshifts: I left foot brake the track car. A lot. It helps fine tune corner entry speeds and allows finer trailing into (and even through some) corners. At the end of a high speed straight before a turn that requires a downshift (or two) the third pedal takes time from the the left foot. I heal and toe just fine, but the ability to nail the entry speed consistently goes way up when you can keep one foot on each pedal. This should improve lap time, and maximize fine car control ability in a really positive way.

I'm ordering my first car ever with 2 pedals instead of 3, and am looking forward to it for sporting reasons at the track, and the increased driver involvement with the other 2 pedals. An auto mode in stopped traffic is side benefit.

That's my $0.02 - Hope I'm right
