Didn't know about that. what about the 300 does it have that? Relative thinking of R300 facelift
Thought it was a little more diff in euro between 528i and 530i, when i compared the 528i went down in price a little and the 530i increased (from N52 528i)
Perhaps i just don't like it I still think its just a 520i with software..
Post-2007 E60 is the LCI version, & only the 530i LCI have N53. Yes, b4 that it was N52 & M52.
E300BE CGI uses the same engine as E350BE CGI, just detuned to 252ps. Again leanburn mode is disabled hence no frt reduction. R300 uses the old M272 engine & hence not the same as C/E300BE CGI.
In EU the 528i before N20 has always been N53, so transition from 528i N53 to 530i N53 is just a matter of engine tuning. Price was increased but only minimal.
528i N20 compared to 520i N20 is not simply just software tuning. Some have different turbo & different engine block. If they're the same then Kelleners would not have quoted different figures for both engines. Also the cost of the engine itself is not necessarily lower for the N20 as it has a turbo plus all those components for direct injection.
I think if BMW made the N20 as a 6 pot turbo then there'll be less resistance from diehard straight-6 fans, but then again it'll be less efficient.
