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)
