So it looks like the X3MC has already tuned up to 610-620+hp and runs a 3.3 sec 0-60... Seems the 500 lb. lighter M4 comp would run similarly, no?

Personally, with the big advantage in functionality (I use the cargo space for work) I'm taking the X3MC tuned as my DD.

Good topic.

But, what kind of race though?
Drag? Road Race?

There are a lot of factors 0-60.

RWD vs AWD

The M3's transmissions ability to dump power over the X3M's slush box.

M3 weighs much less

If the X3M gets a jump on the M3 it will quickly go a way.

[Np2014]

The 500 lb plus difference, rwd, and dct will help the M3/M4 in a longer distance run win against the X3M. Shorter distance run the X3m because of the awd jump at the line because the M3/M4 will struggle to put all that power down unless a perfect launch which is rare for rwd. That 500 lb plus difference is the equivalent of an extra 3 grown adults in the vehicle that's alot to make up for in engine power to compete.

Was really just thinking 0-60, around town, off the line. Hoping the X3MC with tune will hang with the new M3/4. Should definitely hold its own straight line. On a track, gotta give the advantage to the M4.

On street with typical driver and tires -- X3M every time.

I'm sure on an actual track or auto cross yes it would get whooped on maybe that's what you meant. But even in canyons this would do just fine.

Unless I am misinterpreting, I think the OP is asking about the upcoming G80 M3 and not the current generation as the new M3 will presumably have the same engine and power as the X3M.

Ah. If that's the case the new one will have AWD and probably be an entirely different animal

[Np2014]

G80 M3/M4 with awd will take the X3mc because of less weight from a traffic light start. G80 M3/M4 with rwd versus x3mc will lose 0-60 because of the X3m awd advantage but M3/M4 will surpass it past 70mph when the tires hook up.

I have x3mc and m3 f80 with KW clubsport , where i pass corner at 220 km/h on m3 (on full relax), on x3mc i already scared on 180, due to the high center of gravity

on x3mc you go much slower than on m3, ofc if the road is not straight

I would probably never go 115 mph in a corner in any car on the street -- wouldn't even do that in my Spyder which is significantly lighter than both. So can't speak to that. You might be the exception to a normal driver. Maybe not =) We're on forums after all.

I think at that speed I would expect the M3 to be more capable though for reasons you just stated. Maybe I'm getting old, ha.

[SWOT1]

Let me clarify! This was specifically comparing a TUNED (Racechip or JB4) X3MC producing 610-610hp VS. the NEXT GEN (2021) M3/4 which we assume will have the same S58 engine BUT will weigh 500-600lb less. Also to note, AWD vs. most likely a DCT or manual RWD.

So my question was, real world, off the line at the red light, 0-60, 0-100... who wins?

4500lb X3MC with 610hp... or
3900lb M3/4C with 510hp (though on the dyno, this will likely be 535-550hp)

So 600 lbs vs. real world 60-70hp difference


I'd expect both to run 3.2 - 3.3+ 0-60 and darn close 0-100

Looking forward to finding out!

That specific example the X3MC at 610 vs Stock M3 RWD, X3M wins big time on a street drag. Stock3 AWD would be equal. A drivers race.

I'm biased (as I'm expecting to be an owner of a tuned X3MC within a couple of months)... but I certainly hope you're correct!!

[guarnibl]

I think if you compare X3Mc VS G80 M3 AWD/Auto, the M3 would win pretty easily. BMW will play with the engine/trans tune + optimize gearing to keep it that way.

X3MC is advertised 0-60 in 4.0. M3 will be advertised probably in the 3.6-3.7 range w/ AWD. Real world will probably be closer to 2.9-3.0 for the M3 and a few tenths off on the X3MC.

Of course, but that was not my question!

THIS:
610 hp X3MC TUNED vs. 510 hp (actual closer to 530-540+ hp) 2021 M3/4

I expect both to be 3.1-3.3 sec. 0-60

If you a proper racing driver and have good experience on track, it does not matter what car u drive - you can always feel a car limit during cornering.

p.s. Here in Portugal, we have a very nice roads (no winter is here) and they are empy and no radars, btw - the craziest drivers on autobanh in Germany, ppls go 300 km/h on normal diesel tuned cars, like a6 3.0 tdi etd

Wrong quest, RWD m3 never will get GRIP, even stock m3 f80 is struggle a lot from the launch.

AWD m3/m4 will be little bit slower, than x3mc with stage 2 (decat+remap)

I don't have any of that. Makes sense. We have decent roads here in Arizona (no winter -- except north) but not like over there. I've driven on the Autobahn, that's an entirely different experience. Had the M4 up to 250 (kph) I think on my Euro Delivery But it was pretty straight. Felt fine too.

Maybe some day I'll track. I just honestly haven't had the interest.

Agree with this statement.

Lighter weight with smaller tire contact may become a disadvantage on M3/M4.
