Nigel Tufnal
With nothing else to do, I read through carefully the product information document in the "stickies" looking for specific suspension differences between the X3M and X3MC. The document does note that the X3MC has "Adaptive M suspension with even stiffer characteristics".
The rear anti-roll bar is noted as "M" specific with "Ø 24.7 mm". No distinction is made between XM3 and XM3C. The only difference I could find is below. "Adaptive M suspension on Competition model (Dynamic Damper Control) There are no EDC control valves as familiar from the G01/G02 fitted on the outside of the shock absorbers but instead typical M-only internal control valves. The shock absorbers have been developed with the supplier ZF Sachs and the system adapted to the F97/F98. The EDC works with infinitely variable valves in the absorbers. The hydraulic oil flow is controlled via electromagnetic control valves. It is thus possible to make available the damping force actually required at all times." This would appear to suggest that the XM3C's "stiffer suspension characteristics" are a function of software controlled damping force. I wonder if, like Nigel Tufnal's amp, the XM3C's adaptive suspension has an 11 setting, i.e., compared to the XM3, in the XM3C comfort=sport, sport=sport+, and sport+=11, or sport++. This could explain why many testers complained that even in the comfort setting, the XM3C's suspension felt stiff (wimps?). |

The specific reason I called out the tires is that at the first dealership where I back-to-back tested the base X3M and then the Comp (both cars on the 21s with the same Conti tires), the difference in responsiveness/turn-in wasn't really noticeable to me. I was able to push both cars much harder on this test drive (nice fast country back roads). At the second dealership was where I noticed a fairly marked difference in how the cars turned in and responded to steering inputs. On this drive the Comp felt noticeably more responsive. I was driving slower on this ride as well due to much more congested/lower speed limit roads. The base car on this ride had the 21s with Contis. The Comp had the 21s with Michelin tires. |

Tires can make a noticeable difference in many aspects; effects turn in, ride compliance, noise. |

Great quote, although unnecessary for the rest of us as we can read the original post. 😀

Not sure comp is worth the money. I just ordered the black grilles and trunk badge for $375! Maybe I'll do exhaust tips later on and the mirror caps.

not surprised that comp version felt harsh - I felt the same way when I drove one. exhaust is a joke. power and even shock valving can be reprogrammed easily.
sounds like regular x3m is the better choice. |

Read this on Instagram and amended my settings accordingly. Only travelled about 10 miles, but on the U.K. B roads I normally use around the house, it has, I believe, made it subtly more accommodating of uneven surfaces.
I changed to correct tyre sizes as opposed to summer/winter tyres and altered to partially loaded. Will see if I notice longer term. |

The X3M is made in America by Americans, so I kind of feel like it would be "buying American" anyway. Yeah, the profits don't wind up in the US, but a lot of other benefits (Spartanburg workers, the community, etc) really do benefit. Just curious, what other American SUV is similar in overall performance to an X3M other than possibly the Jeep SRT? Which by the way also rides pretty poorly and handles significantly worse than even the base X3M. Not to mention the cheap interior quality, relatively low tech (do they even have a 360 surround camera available yet), poor reliability and terrible resale value. It probably doesn't help that it rides on a 10+ year old platform at this point in time either. |

Maybe but why the fuck are you worried about performance if you're in a SUV/SAV? Lol doesn't make any sense. I would take an Escalade or even an XT6 over any European suv/sav right now. Utility, comfort and ride is all that matters.
