Will US cars have the Otto Particle Filter (OPF)?

As the title says, do we know yet whether the US G80/G82 M cars will have the OPF like the European counterparts?

Really hoping for them to do what Porsche did with the 992 where US cars aren't coming with OPF filter.

In any case, nothing that a good, old reciprocating saw can’t fix.

I don't think so it's Europe only as current cars don't have them.

No reason they would, filters not required in the US. And they have not done it on any other model.

Mostly likely no. OPFs only required for EU, China and Japan iirc.

Remap shouldn't be needed if there aren't any sensors located after the OPF.

I have to go find a US spec GT4 review now.

Does OPF affect performance?

I'm actually surprised BMW doesn't put them on US vehicles anyway. I recall BMW saying they were going to adhere to the higher fuel efficiency mandates even after the US claws back the severity of the regulation.

It is for emissions not fuel economy

Actually i believe early implementation did affect engine output on some versions, I think the eu m340 is still rated at 374 hp and the z4 launched in Eu with 335 hp when the us had 382. Not sure if that is 100% opf related

You must know the goal behind fuel economy standards is to reduce emissions; no? I took this understanding for granted when I commented.

you are correct, the euro one had the same engine but it output way less power due to the OPF

Well it's technically accurate if motor uses less fuel it will have lower emissions. However the opf filter has no effect on how much fuel the motor consumes, so your statement while true in a general sense was not accurate in relation to the function of the OPF.

I will also add without diving too deep toward topics that belong on the politics subforum the US has pretty separate legislative drivers in setting standards for emissions and fuel economy, the whole foreign oil dependance/depletion of resources discussion. But it is true there is an interdependent relationship.

I considering the detrimental effect to the vehicle (sound, performance) I doubt bmw would reduce the vehicles market appeal just to jump ahead. They much prefer the marketing benefit of touting their fuel consumption being ahead of the standards but that is mostly due to superior engineering combine with stricter euro standards... they can engineer a 382hp motor that gets 30mpg in a 3900lb awd car.... not many other OEMs can

Unfortunately, remap is necessary in this case. There is a sensor that detects the pressure. If it falls out of range, you donít just get a CEL, but you get limp mode. Itís pretty well documented at least on the M2 forum if you get bored.

I didn't know that, thanks, are we sure it's the OPF and not a different tune to account for the OPF? Just curious as that's a large difference!

The 10 KW difference for the M340i is still present I believe.

I believe the rather large difference for the Z4 is/was due to packing issues for the OPF, i.e. BMW couldn't use the same exhaust treatment package as for the M340i (but a smaller one I guess) so they had to massively detune the engine in order to follow regulations.

On the z4 they actually just went with the lower output version then the next year with the m340 launched finished figuring out the packaging needs. It is still down 8hp vs the US market version... 374 hp vs 382 in both cars. For the G8X motors they have listed no power difference between us and Europe cars (just the usual metric hp vs sae, 510hp eu and 503hp us)
