Hi guys

I just swapped my F90 M5 for an X4M (I'm downsizing my payments).

Driving it home today I notice if has very little torque from a standstill. It only picks up around 3000 rpm. Is this normal?

I previously had test driven an x3m demo and it didn't seem so bad. I hadn't driven more than 3-5 minutes... maybe I missed such a big gap in torque but that seems unlikely.

Could this be related to break-in period limiting torque?

I bought a bootmod3 license as a last resort to hopefully remedy this but hoping you guys will tell me I just need to wait it out (it currently has 50KM).

This is how the engine is.

Nope, tis how it is. I came to my X4M from a X4 35i with 300hp & 300lb-ft and was shocked at the lack of torque down low.. I can only imagine your sensation from a V8 M5. I got used to it, but maybe cause I never knew any better.. good luck, tell us how it feels in a month or two.

But in all honesty, the thing is brutally fast regardless

Use sport throttle. This helps a little, but don't expect real power until 3k+ rpms. 5-7k are a real hoot though. Personally I find the lower rpms fine for moving about town, especially since throttle response is so tight.

It is the part of the engine characteristic that I like the least, too. The GLC63 got it right, IMHO, with a larger torque-rich V8 engine from low revs, whereas the S58 engine probably is better suited to the M3/M4, rather than a heavy SUV/SAV.

In town and in D1 it feels like a 300 bhp engine, albeit a very nice and smooth one.

There are no limitations on tq, launch control, hp or anything acceleration related during break in period. Don’t go over 5kish rpm either or use LC.

It’s normal for inline 6 to feel low torque vs v8. But I can tell you the top end of this X3m is much more enjoyable than the v8 from my X5m (and probably your f90).

The main issue I notice from the 6 is the non linear dip in power between 2.5k to about 3.2k. The start off is fine for me, but if I get caught trying to push the car in that dip it sort of lags and then boom.

After driving it for 5k miles, I’d stay above 4.5k to keep it in the sweet part of the rev range.

Depends on the tuning - the S55 doesn't feel sluggish in any part of the power band. I would bet the new G80 will not have a lack of low end torque either.

man, bm3 adds so much torque, I don’t know where to waste all the torque I’m getting from this engine now. the midrange push in the back is insane now and shifts are violent. feels like Ford GT500.

My 4.4i v8 had more low end torque vs my s55 f80 m3. top end the f80 just explodes.

I've had a lot of v8's, including the 6.2 merc v8 amg and down low is more enjoyable vs a 6.

Like others have said. It is normal and the break in will not change anything. Power does not come on until 3000RPMS +

BM3 may add more TQ but sub 3000RPM it doesnt change, it still lacks downlow which sucks especially when driving on the highway.

You actually have a tuned X3M?

when driving on the highway? what are you talking about?

to get a better picture of the lag you can compare numbers from 0-60 with a 1 ft rollout and 5-60 rolling start in 1st.

F80 competition (per car and driver)

0-60 4.0 seconds
5-60 4.6 seconds
delta 0.6 seconds

X3MC (per car and driver)
0-60 3.3 seconds
5-60 4.7 seconds
delta is 1.4 seconds

delta is .5 for the f90 m5 competition, and .7 for the '16 x5m if you're curious.

And your torque as well.

well, my 5-60 is now 3.8 seconds

I think this summarizes my issue best. 5-60 is driving me bonkers. I used to have an f86 x6m with jb4 and it was so much more forgiving for not being in the exact right gear at the right time. I think BMW needs to add a small electric engine to compensate.

Anyone know if default D2 can be coded in? I have BimmerCode.

This is going to be a very long 36 months....

is there any way you can get rid of that lease? There was another guy who switched from F90 to X4M and he ended up getting rid of his X4 within the first few months.

Yes, 5-10K will do it for sure. The goal was to reduce the spend on my second vehicle. My summer car is a 2020 (992) C4S Cab.

The dealer was kind enough to do essentially a "key swap" from the M5 to the X4M (no balloon) so long as I took the one with the strange seats (orange inserts) that I guess they were stuck with.

I'll tough it out for the winter but will probably be looking for a used Cayenne Turbo (2019) or X6M (2020... which will be harder to find I guess). The good news is those SUVs depreciate like a planet killer asteroid crashing through our atmosphere.

In the meantime... I will tune this x4m, code it, etc and work tirelessly at making it fun

I know, I'm weird and make impulsive decisions I regret all the time ! (Except my 2012 e92 M3 DCT with X pipes and my 2016 Ferrari California T... I loved those every second I had them).

Depending on how far you want to go with tuning, these cars can be made very quick, fun, and visceral. The best part about this S58 engine is that it is very tunable and comes with forged internals - adding 30-40% hp with e-mix tunes is pretty safe.

Yeah but there's way too many variables at play here as the X3M is much heavier, has to power 4 wheels, and far less aerodynamic so taking launch out of the equation it's got other factors at play holding it back compared to the F80.
