conflicting reports...
Mazda's Skayactiv diesel is all aluminum. It runs a low (for a diesel) 14:1 compression ratio so the components can be lighter. It also doesn't require Adblue or other exhaust aftertreatments.

Daimler’s press information is very accurate (as it should be from most large corporations, no matter what their business line).
You can rest assured that the OM 651 has a cast iron block even though I do not have any other supporting material.
As far as the V6 engine blocks and heads go, they are made of aluminum as far back as 2006 as per the following links:

The Nanoslide technology is truly amazing – from AMG engines now to diesels:

Congratulations to any of you guys considering getting a vehicle with this engine and kudos to MB USA for bringing them to our shores (finally).

I wish they brought the E 250 4MATIC in wagon version.

Cheers.

Quoting from the above mentioned page on the OM 651:
"The cast-iron cylinder barrels have been more finely honed than in the predecessor model and as such help to improve consumption."

You may need to use the translator. Look at the paragraph “Grundmotor.”
