I would like to correct a few satements though. If you have any questions about the vehicle or the tech inside or anything, feel free to ask. It's my job to basically know everything about those vehicles and the tech inside and out.

Thanks! Will do.

On the bright side, the B58 makes more torque than the N55 in the M2. BMW also typically underrates their vehicles. So, the M240i is rated at 335hp, and if the car were to see a dyno, it'd likely put close to that much down at the wheels. Meaning a tune and some exhaust/intake work will put the car at nearly 400bhp.

Correct -- I worded this extremely poorly. By same, I meant same general output/same class, as opposed to other N20/B38s found on other 2-series. Until recently there was a lot of suspicion that the B58 or a variant of it would find it's way into the next M2... but I think they already had a lot invested in the S55 and stuck with that general design for now from what I understand. Pretty poor wording on my part ha.

The XDrive models (especially with the Cold Weather Package off a lot in Utah like mine) very frequently come with the run-flats (at least at the two dealerships in my area). They also often run the run-flats square, though I will be running a summer/winter setup and will go staggered (225/245) in the summer and square in the winter, most likely. If I had ordered or done Euro Delivery, I would have just gotten the MPSS right off the bat. This was basically a "remaining inventory on the lot" end-of-model-year pricing (as good as you can get for BMW, which isn't always that great especially for something like the M240i).

Nope, but the twin-scroll does help quite a bit. I don't so much care about immediate power-delivery like a good NA car, but more that I can tell that the engine is at least trying. The M240i seems to leave a lot of dead room on the pedal (even in Sport) likely so it still fills the luxury car vibe. I didn't see the same issue in the M2 when I test drove it. So maybe pedal response is the term I'm looking for over throttle response?

Even more rear bias or the option to choose on-demand (which the dealer told me is showing up on the full M platform in the next year or two) would be nice, but I'm still very happy with it. XDrive was a compromise both due to available inventory and a wife who wanted me to be as safe as possible in the winter. The XDrive+winter tires combo should do well when the snow hits, even if snow tires alone on a RWD would have been plenty good enough. I am surprised by how much I like the XDrive system, though.

Both of which use one twin-scroll turbocharger.

Correct, twin-scroll turbo, not twin or biturbo. Big miss on terminology for me there
