First of all... sorry to be a stickler but...
-Going through the sources of info (from BMW) there three different average consumption numbers (all UK mpg) given for the LCI 535d was 40.3, 40.5 and 41.5 (as you stated above)
- This means LCI 535d improvement it is somewhere between 14% and 17.5% depending on which number is correct.
- I see the following numbers (on the BMW UK website) ... E90 & E92 335d ... 37.7 mpg
- so if now compare the worst LCI number with the E92 number (i.e. 40.3 to 37.7) we see it is 6.9% improvement over the 3er
So let's think about how such a saving could be made with the 'same' engine in a slightly bigger and slightly heavier car
- brake energy regeneration is advertised as saving an average of 3% (that accounts for almost half of the improvement)
- the engine might look to be the same but we don't know what additional modifications they made to this M57 variant for the LCI. Although hp and torque look to be the same, they may have changed something to make it more economical
- long shot but the E60 is slightly more aerodymnamic with a drag coeffiecient of 0.28 (pre-LCI) compared to 0.30/0.29 for the E92/E90 respectively. I'm not sure what impact this could have on economy in the real world
- it's quite possible that the new transmission was further modified either mechanically or in software from the one in the 3 series (we don't know yet). The current theory is that they are the same...
Hope this helps in your analysis...

- Varioserv steering assistance pump, varying the curve ring as a function of pressure and volume flow, avoids the usual increase in drive losses as a function of higher engine speeds.
- when the driver and passengers do not require the air conditioning, the a/c compressor is disconnected to reduce drag forces to a minimum.
- active management of the brake and cooling air flaps serving to improve the car?s aerodynamics.
I don't think the 335d has any of these features....

For the e60 I read that as a future fuel efficiency development along with electric power steering.
The current BMW UK Magazine (Winter 2006, pages 30 & 31) has quite a few details on Energy Management and the role of these developments in current BMW cars and forthcoming models, including an interesting paragraph on the new auto box's complementary clutch mechanism and how the torque converter is used almost exclusively for moving off.

Is this the same as closing flaps in front of the radiator when cooling not needed to improve aerodynamics?

I got that quote about the flaps for the worldcarfans article about the LCI and it looks like that is nothing more than a more verbose BMW press release...
So it sounds like they might have cracked it sooner rather than later. I'll be interested to learn more about these motorised flaps and how they work.

The revised 5 Series goes on sale this March, and BMW plans to introduce other technologies across its range during the year that will also improve efficiency. These include low-rolling resistance tyres, start-stop systems that switch the engine off when the car is stationary in traffic, electrically powered air conditioning compressors and water pumps, electric power steering, and flaps behind the radiator grille that reduce airflow when it is not required.

So it's probably more reliable than the quote in the Fifth Gear article:

Looks like they have managed to squeeze most of those goodies into the 1 series facelift annouced today

What a figure - 25% of 1 all Series sales are in the UK. What does that tell us?
that's Brits are creatures of small stature?
What does it tell us ABC?
