Perfect example of "who cares?" I hope no one is making $90,000 decisions based on which car prevails in some 0-whatever race that most likely would never happen in real life. As long as we all make our choices based on things that actually matter to each of us, we all should be pleased with our choices. There may be a few who really do value fractional race "wins" against a competing car over things like every day usability, comfort, appearance, sound, etc., but I expect the vast majority of us care much more about how much we enjoy the car when we drive it each day than whether it would beat by a fraction of a second some other car.

Curious the outcome vs a Trackhawk.

Not that it matters $3 in mods puts it in the 9s anyway (obviously exaggerating, but not but not by much :-D )

You would be incorrect

LC is always controversial with many saying it's complete garbage. If they had used it and the outcome was exactly the same people would be blaming the LC.

As much bc as we want the X3M to annihilate every competitor, it didn't, let's just live with it for what it is.

Or don’t race it if you are not competent. Racing is not for everyone and that’s ok.

Without using LC, the X3M will get a hefty serving of Gapplebees from the Jeep. Even without launching the thing rips off the line.

That motor literally has instant torque. The only thing I miss about my Hellcat, plus that whine.

I am hunting for TrackHawks daily in the X3M. No luck yet. Once I find one, I will launch on it and see how it does.

Good luck! Find it, launch it, whip it!! (let's just hope its close... tough to compete with 700hp)

Actually, funny you say this! I was just thinking something like that the other day driving my wife's car - we have both. The M40i has a much smoother power delivery for sure! I can see what you are saying, for the power both cars have, the M40 is not too much slower. My car is much more "in your face" about it - more "rough" I guess... I have not used LC yet actually, normal launch is plenty quick for city streets. Without even pushing the car, I usually have to break or back off hitting 3rd. Plus, I am more into lap times than drag times... It's funny though, being the "same" car, they feel nothing alike! I do wish the cold startup sound remained and didn't fade after it warmed... This is my first M car, and after experiencing the difference, I can never go back 👍🏼😂! Going to try snapping up a low mileage 2018/19 M3 at some point as a project car.

If you find a 2019 M3 I suggest you grab it up immediately. They are more rare than unicorns!!!

Yeah, hope to maybe catch one coming off lease while the dealership is hyping the new one... 🙏🏼🙏🏼

typical supercharger vs twin-turbo outcome. Jag’s supercharger helps getting that brisk start, but the torque tapers off much faster. If you want a drag racer, take the supercharged Jag. If you love breathtaking mid-range and high-end rolling acceleration (and I definitely do), take the beamer.

Pretty impressive!

Why is LC controversial? It makes great sense building boost to help with turbo lag. And it is more than just boost.

The LC in my f86 is absurd. Transmission sounds and shifts different than any other mode. It's eerily smoother. If I had a G-meter I could try and quantify whether or not the launch is actually enhanced. Alas my old Vericom VC200 is broken. Maybe someone has done a LC g force check or has drag strip times.

One can only wonder why they didn't use it. For both.

And is a v8 v i6 a meaningful comparison? In my mind the x3m here is punched up and out of its weight class and KO'd the bigger opponent. Perhaps the comparison is made based on vehicle weight or cost.

Of course is meaningful, they both play in the same class, same as M4 vs C63, one is v8 the other is i6, so what, same class of cars

The X3M is a monster once you get RPMs up, insanely fun to drive, but from a dead stop it can be brutal, feels no different than a M40i for that first 1-2 seconds.

Would have thought the S58 in the m3 weighing quite a lot less than the X3M will be a serious weapon 👍

In the real world launch control is bs. Anyone going LC at a stop light to beat Betsy soccer mom to the merge before next light has issues. Drag strip is the only place LC has actual utility. I do however want the car to move when I put my foot down in normal situations without brake torqueing every time I need to get going.

Welp, that's one more I've got to add to my already long list of issues

The smoothness you felt with the M40 is really the immediate response to pedal input, while the roughness from your proper M car is when power comes with delay and the car jumps unexpectedly.

I test drove the X3MC and to me it's a sluggish car for its class in traffic, compared to the F82 ZCP or the AMG GLC 63, or dare I say even any BMW with a B58tu. Though I'm sure it'd be a different story as speed builds up.

The S58 needs a TU, or the G80 would be a better car carrying over the S55.

Well thanks for the insightful info. Are the vehicles same dry weights?

I have owned the F82 ZCP and my X3MC (an SUV!) comes extremely close performance-wise. It is not a “sluggish car” by any effing means. It is as fast as the GLC 63s coupe (not the regular 63) and will absolutely wipe the floor with any B58 beamer in any setting (yes, I had an X3 M40i for 3-4 months prior to buying the MC). Few questions to your test drive. Were you even allowed to rev it up (break-in service)? Did you play around with different engine/transmission settings? Did you warm up the engine in an appropriate manner (because warming up the S58 takes a while)?

I agree...

If anyone thinks the X3MC is sluggish...they simply are not driving it right. The car absolutely MOVES. I came from a Tuned B58 in an M240i...and at first I actually thought my M240i felt quicker. But now that I'm revving my X3MC out more and towards the end of the break-in...no way was my old B58 car quicker. I think the power curve and how the S58 makes power throws some people off...its such a smooth wave of torque/power, it kind of masks how fast it actually is. Did a little pull on the toll road today and looked down and was going 130, without even trying or noticing. It is M5 fast...

Maybe if you have it in Efficient and D1 and don't rev it out...it might seem "sluggish"?

Cant wait to tune my next summer. I am already getting 3.3 0-60 on the a/s tires. Switching to summers....well, in the summer.

Please take a look at my fully loaded less than 8k miles 2016 M3, I’m reluctantly putting up for sale as taking delivery of X3MC in January. Would love to see it go to a good home!
Thanks
