Another reason that the diesel is popular in the UK is the carbon emission. At only 159g/km, this is far less than even small petrol cars, and as such I feel good knowing that my environmental impact is far less than most other cars on the road. In the UK, company car tax is based on carbon emission, not milage, and as such

1. I am being realtively green to the environment
2. I am paying low company car tax (19%)
3. I get excellent milage when I'm on my personal time and paying for the petrol myself.
The day of the diesel will come to the US in due course.
The trouble is that diesels fail the California emissions requirements and three or four other states (and key US markets) follow the CA regs. CO2 emissions may be low, but the diesels today fail the NOx requirements. EU regs focus on CO2 and allow higher NOx (as it is difficult to meet both). California regs have the same limit for both and the high NOx - which is not a good thing - is primarily why they fail. There is work underway to address the NOx issue including the Urea injection system (and also the diesel formulation here is switching to low sulfur which also helps), until then they're not able to pass the regs here unfortunately.

The urea approach is what Mercedes uses with their Bluetch technology together with a NOx storage catalyst. So, its doable.

Isn't this because of the diesel in the US is very "dirty" compared to Europe?

Diesel is quite a bit cheaper in holland than Petrol (Premium). But even if it were slightly more expensive like in the UK or the US,... Diesel cars are up to twice as economical as their Petrol counterparts. A full tank in a 520d can do 1400km's and in my 535d with 272HP, can even do 1000km's if i am gentle on the throttle (800km's on normal driving).
I have to support that all the way! I just finished over 3.000km drive through Luxembourg, Germany, Poland - and back; and average consumption in my new 520d was 5,7 L/100km!!
OK, as advised for the first few thousands of km in a new diesel I was driving quite carefully, ony few times getting close to 180-190km/h (in no-speed limit zone on German A4). But otherwise 130-140km/h + some landstrasse at 60-80km/h.
But, overall I am really surprised with that result because it gives you easily about 1300km range, which is amazing...
I only filled up in Luxembourg (about 0,947 EUR per litre) and then next fill-up in Poland for pretty much the same price, and the only stops in Germany were for... a best Grillwurst in Europe & a small glass of the golden Bitburger... forgetting about the fuel...
What an amazing car this BMW!

Yes, it's getting closer - and major credit to Mercedes for getting this to market first. Unfortunately the 2007 Bluetec's still won't be 50 state legal though, they're not going to be offered in the states that follow the CARB rules. Later iterations should hopefully meet the requirements. Would love to be able to test a MB Bluetec against a BMW diesel.

Not specifically, the different formulations are certainly a part of it and that is addressed by regulations changes that are just about to take effect. It's just the different emphasis on emissions. To a large extent diesels now are paying the price for the sins of the shockers that were available 20 to 30 years ago and the regs effectively legislated them out of existence - in passenger cars. Trucks are subject to different rules and bizarrely are available. Either way we're getting close - hoping to see the latest generation of BMW and MB diesels here soon as I think they are going to fly out of the showrooms. I think there are going to be some major changes in perception once the latest Euro diesels hit the scene. Car and Driver here just did a short comparison of a 330i vs a 330d and they were pretty (actually very) impressed.

My Ride: 2010 523i. Alpine white, dakota leather, 8 speed auto, VDC, bluetooth, HID lights, parking sensors, sport seats, black window trim, tinted rear windows 1988 Ferrari 328 GTS, nero on rosso corsa. 1992 Mazda MX-5 / Miata 2009 Ford S-Max 2.5T

I have an I-Drive screen photo which I'll post later that sums up the 530d. This was on a trip 4 up with luggage:

Distance travelled: 212 km.
Average fuel consumption: 7.9litres/100 km
Average speed: 150.0 km/h

I think that's pretty impressive at least I was never able to achieve this in a petrol car. It's my first ever diesel. I love the steam engine low rev torque but miss the sound of revving a petrol car to the redline and really hate the start up clatter.

On balance I'd swap the auto 530d for a manual 530i.
