My question is not about what car is faster. My question is why did BMW move from 545 to 550 right the middle E60 production?
Does anybody know? Is it some kind problem with the engines, and they are tried to eliminated it.

This is BMW's way of making design changes without completely overhauling the model.
Most of the changes are cosmetic or introduce new features/options. However, some involve slight drivetrain improvements (like the 545i to 550i conversion) or complete drivetrain overhauls (like the 530i to 535i conversion)

the n62 was updated for the e65 2006 update, and the E60s got the updated engine as well. BMW does that often since their engines are common across various platforms. 2006 also saw the updated 6 cylinder engines from the E90, so the E60s got those as well, even though the badges didn't change.
aside from a switch back to a bosch alternator on the V8, i don't know if anything else was rectified along with the upgrade.

The updated engine fixed the water transfer coolant pipe issue among other things, I believe. BMW engine developement does not follow body/car developement cycles (necessarily). I believe the 550 pre-dates the E60 LCI

There is nothing wrong with the 4.4L engine. It was the basis for the Alpina's supercharged powerplant in the B7. Now, of course, it is the basis of the new twin-power turbo engines in the 550i, 650i and 750i cars.

I'm still learning about BMW V8 engines, because I had 3-series before only. So I know starter was a problem on e46 engines, so do you have problem with starter on V8 engine?

I remember reading a few threads about starter/solenoid problems with the V-8's. Not many though.

Maybe your E46 had starter problems but my 2002 E46 with 117K on the clock has never had a starter problem (knock on wood).
