I realise that the 3 turbo engine may not be able to fit in an RHD car due to the position of the steering column, but what I'm not clear on is that the old Alpina diesel which is still available in the D3 and D4 makes more power than the new engine, 257kw versus 240kw

I find that a little disappointing. Also what is interesting is that as far as I'm aware the 540i and 530d are the highest engines available in any RHD market G31s.
Alpina UK doesn't show a D5 S G31 only a D5 S G30, but they have both G30 and G31 B5s.
Slightly different topic, an interesting thing I noticed is that the only way to get a RWD 6 cylinder G31 is the 530d. Every other option for 6 or 8 cylinders is 4WD. The G30 however is available as a RWD 540i.
