with 177 bhp on the way, where does that put the 525d? other than being a six other than a four, its going to be hard to justify the extra spend...
I would say that the updated 525d would be a better base to tune from... The 177bhp 520d will already be in a high state of tune whereas the 525d has some way to go... (240hp easy)

20hp, 2 cylinders & 1 litre ahead...

IMHO there's a significant difference between the 2.0d engine and the 3.0d engine. Not something you can measure just looking at the stats. I recently drove in an E90 325d and the 3.0d felt SUBJECTIVELY significantly smoother than the current 525d (2.5d), which I have also recently been in. I think the gap between the new 520d and 525d models will be larger, as both engines will be using the latest technology, whereas the 2.5d engine was possibly a little dated in comparisson.
As for the 520d vs 525d, the 525d is smoother and quicker - not to mention easier to tune (see post above). It all comes down to money. I would prefer a 6 cylinder any day, but fuel & tax costs now a days have made the gap bigger and sometimes totally impossible to justify - especially with company cars.
Glad to hear you are also enjoying the 520d!

I agree with you guys, yes it doesnt have the smoothness of a 6 cylinder, but for what it is, its a amazing engine. It is really rev happy and does pull extremely well. Its the unsung hero of the E60 range. I know you shouldnt compare it to a petrol boxer engine sports car, but with 340nm of torque, it matches a 3.4 litre Porsche Boxster/Cayman S engine. For a 2 litre that is exceptional!.

Had a 520d auto as a loan car and what a great car it is. I was amazed at the pulling power and smoothness of the engine. No wonder you see loads on the UK roads. BMW should have released the E39 520d in the UK, they'd have sold more cars.
Diesel tech have raced the last few years.
Anyone remember the old E28 524td?
The BMW M21D25 engine gave 115 hp and a torgue of about 210 Nm.
BMW sold that fine diesel tech to GM for Opel (Vauxhall) Omega (with less juice).

As the 7-month owner of the new 520d I have to admit and agree with you: it is a great car.
Power could be better, however overall performance for everyday driving is really OK (compared to my previous 528i - it's far better!)
And not to mention the economics of this engine...
My last week's 2000km ski-trip to Austria resulted in +/- 5,5l/100km average (90% on autobahn, usually according to the limits: below 120km/h, but at times well above 200km/h) - for me the best part of this car!
Oh, and the last thing - insurance rate I pay: lower than my friend paid for his new Vectra... Amazing, isn't it??

My E90 320d gets an average of 9 l/100kms (31.3 mpg UK, 26 mpg US).
That's 70% city driving (short 5km runs to work, a few hills, non-aggressive driving style, manual transmission)
BMW say I should be getting 7.8 urban, 4.5 extra-urban, 5.7 composite. It is true that on very long drives I can get around 6.5-7 l/100km. I've never managed to get the numbers you are seeing but I live in hope and will keep trying :-)
In conclusion... in urban driving with cold starts, even the small 4-pot diesel can guzzle fuel but is still better than a similar petrol engine which would be even worse. On long drives (cruising), my experience is that many petrol engines are fairly close to diesel.
