350cdi / 320cdi V6 what's the status
Sometime ago, I saw press announcements that MB were intending to replace their 320cdi engine with a 350 v6. Now, I am little puzzled. I can't see any reference to an E350cdi on MB sites. However, they have upgraded the 320cdi to V6. Can someone clarify? are they both available. Has the 350cdi been shelved. Is the 320cdi on the way out?

The new V6 diesels also have staged turbos which will eliminate the turbo lag on the current CDI's.
As for aluminum blocks, I think they might be more reliable than the combination of cast iron block and aluminum heads that our 1984 190D had. Of course we had no problems with it during the 17 years we drove it and my former neighbor hasn't had any problems during the 5 years he's had it.
Seriously, I wouldn't worry about the new V6 other than the complications that rail injection and tri-turbos might cause. The simplicity of mechanical injection pumps are long gone.

)How can an aluminum block be more reliable than an iron block? The words "physically impossible" come to mind..

There is nothing wrong with an aluminum block. This one has cast-in grey iron cylinder liners which is what's important. So long as the block provides adequate support for the bottom end, what's to worry about?
I would not buy one for a year or so but then I wouldn't buy any new technology right out of the box (including BMW's new I6).
Why worry? The vast majority of initial buyers will never find out how long the engine will last. There are many advantages to the new engine including smaller size and lighter weight. It has a shorter, stiffer crankshaft. It has tri-turbos. It has a cylinder head of the same material as the block.
I don't like V6's because they have a coarse sound to them when pushed. Otherwise, I can't say that my BMW I6's were any smoother running than my E320.

got it! and I do agree about the lasting thing...we'll all trade them in inside of 5 years anyway!

We drove our 190D for 17 years, I'm still driving my 1991 300E after 14 years and I have no intentions of selling the E320 any time soon.

The 7speed cannot mate to the I6 for space reasons.

I just hope there are no problems because it could really crush their reputation.

2001 MB E320
i wonder if MB decided to go aluminum block but using an iron sleave for the cylinders. if that's the case should it compensate for pressure inside the cylinder for better strength and long lasting durability?

ML 320 CDI
The new E320 CDI comes as standard with the 7-speed box, seems ok too although some people have reported harsh gearchanges I think software upgrades to the box have eliminated the problems.
The one thing I did notice was how sluggish the car was untill it warmed up properly. Apparently this is a feature so the cast iron cylinder liners heat up at the correct temp and not to fast which could cause problems as iron and alluminium expand/contract at different speeds/temperatures.

Does anyone know if these engines are used in diesel taxis? Mind you, that still is not my worry. After all, you start the taxi once in the morning and it's running all day. It's the start up and cooling down in northern climates that worry me. Up here, you can have -25 C. in the middle of winter and that should just put one hell of a shock into the system. On top of that, the high pressures of the diesel engine. OUCH!
I guess that by the time I am going to buy my next E, these engines will have 8 years under their belt. By that time, it will either be a success or Mercedes will be replacing engines....or cars.

On another point. Is it possible to (visually) tell the difference in a E320 fitted with V6 compard to the old engine. i.e. slight external differences or is it all by looking at the engine or VIN number?

The iron sleeves inside Aluminum flies the the face of what I learned in material science classes... those metals have different heat properties.
If you look at this picture from the Hydra website, the cylinder walls seem to be missing.. so maybe the steel sleeves fit inside and have no aluminum around them.. which would assist in the expansion. However, the top of the block still is made of aluminum where those sleeves must be inserted.
I don't see why MB sold out to the V6 cost cutters! BMW is now the only company (to their credit) still using the superior design of the I6.

that picture is actually of the 2.0L I5. I can't find a large pic of the I6 anywhere..

It's also more difficult to design an I6 to get equal inlet flow vs. the more compact V arrangement. Then there are other V6 advantages in size, weight and stiffness. V6 engines also offer more options in transmissions and drive train choices.
Yes, V6's are probably less expensive to produce but they offer a great many advantages to the consumer.
I'm a long time fan of BMW sixes so it's taken me some time to admit that my predudice was keeping me from seeing the whole picture.
