Diesels are the way to go..with more torque and improving NVH characteristics of the later generation diesels...they seem to give the petrol siblings a good challenge in terms of top speed as well as accelaration..

Also, they are lighter on our pocket..atleast in India..

Here, AdBlue, a non-toxic aqueous solution, is injected into the exhaustgas stream, causing ammonia to be released. In the downstream SCR catalytic converter the ammonia then converts up to 80 percent of the nitrogen oxides into the harmless natural products of nitrogen and water.
from the article....

But is American gas stations ready to dispense ad blue?? are the ready with logistics of ad blue??? Well.. I dunno whatz the big hue and cry about BLUETEC.. whatz the point in having a merc.. If yu can fill it up only at the Merc. service station???

The problem, of course, is the need to carry and replenish the AdBlue aqueous urea solution. The company said since an average of around 1.0 gal. of AdBlue is needed for about 2300 miles of driving, the AdBlue tank can be refilled during scheduled maintenance, taking it out of the hands of the owners.

Hi.. Did you ever check the website of Merc (Blue tec).. It says fill it up at stations on your way.. or have your own tank.... you can fill it up from a canister too.. and the range specified with a 90l adblue tank is 6500 kms... (of course this is for a tractor trailer)...

so maybe you need to service youur merc every 5000 kms... OMG... Merc is going to have a field day with service...

and then I don't Feel It it cvan be refilled during scheduled maintenance.. can you give your reference on that and 2300 miles for a gallon is quite high comparing with that of trucks??

6500 for 90l = 72kmpl
take double ( being the engine displacement half of that of trucks)
144 kmpl Your figure is around 20 times that

Non CV mainstream diesels have come a long way in the US since the days of the sooty old Oldsmobile V8 diesel.
Ford/Dodge/GM are bringing in highly tweaked (for an American vehicle ) versions of their Duramax/Cummins/Powerstroke diesels in their heavy duty pickups too.
BTW, I dont understand why Ford cannot bring in their Euro-spec TDCi (2.2L) engine for its small SUVs and the Fusion/Milan/Zephyr with a manual transmission. It would give great FE and they can launch it in some states for starters..

According to figures from the USA,The normal E320 cdi runs about 570 miles on a tankful[21.1 gal] with bluetec it would run about 760 miles i.e bluetec[non hybrid],while mercedes is working on a hybrid version of the bluetec as well whose fe would be even more.

Hi Rahul.. That article doesn't say that you "can go upto 2300 miles on a Tank Of Adblue & that adbue can bee changed during routine service"

I met a guy from Pure Em today who makes the SCR systems for Merc truck... The mileage is like 3-5% of diesel consumption...

maybe that might be for trucK... anyway.. if you cahange at routine service.. well and good..

Psst:- Does anybody know that in the PureEm system.. It cannot distinguish betwwen Adblue and water?? Like if you put water in the Adblue tank It will still run fine???
