My Inline Diesel Experience

MY 83 inline I4 240Diesel has 355,000 miles on it....runs great. My 05 E320 I6 has 100,000 miles on it and runs great. My wife's 05 E320 I6 has 65,000 miles on it and runs great. My Kubota I4 diesel has a couple of thousand hours and runs great. Nothing wrong with a PROVEN design. When the V6 gets about 10 years on it, we can properly evaluate it.

Long time. I love my inline 6 a lot. To begin with there is no pre-cat and no particulate filter to replace. Ever.

As a result there is no pesky check engine light to worry about.

From 2009, the V-6 diesels will come with urea injection. Disaster for new owners and very profitable for the dealerships. I wonder how the new diesel owners like the cutting off of power when the urea is low?

Love that tree.
Hate that urea.

07 and 08 without UREA Bluetec V6's seem good to me.

Sob! Sob!

Such a pity. The Honda-Acura diesel inline 4 was to have 170 bhp and lots of torque for the North American market. All without urea injection. Hooked up with a 6 speed stick or twin clutch automatic this baby can really give Audi a run for its money.

The excuse was the inability to pass emission tests with the automatic. I think it is a load of "crab". The bad economy and high diesel prices in America are the likely villains killing the import plan.

I agree but their marketing guys will never do it for us in North America. Diesel cars, like station wagons, are considered lesser than gasoline cars and sedans and MB cannot afford to lessen its carefully cultivated image here.

Agreed, on both counts.



Lets be realistic here. The two reasons MB went to a v6 was to reduce productions costs and make the engines more "fittable" into all model lines. In 1998, they introduced the 3.2L SOHC 3 valve v6 to be made in the same production line as the 4.3L 3-valve v8, which just so happened to have the same displacement per cylinder as the v6. Thankfully, they put enough into these motors to make them as durable as the earlier inline engines, at least at first glance. In the same respect, I am 99% sure that the new 3.0L diesel V6 will be built on the same line at the 4.0L v8 diesel, once again reducing production costs. The new v6 diesel could very well cost more than the old inline engine per motor, but I can all-but-guarantee that the development costs of the v6 & v8 diesel engines combined is less than the previous inline-6 and previous v8 diesel engines combined.



Mercedes could have easily met the current "more stringent" emission standards and and achieved greater performance with an inline-6 engine by incorporating more modern fuel injection. Lower engine mass is a benefit of using a v6 over an inline, but I highly doubt this was a major factor in deciding to switch to a v6 in a 4000lb E-class.



I disagree! (in similar fashion to the "drive-by argument" in one Family Guy episode)



Agreed.
The new 3 liter V-6 diesel and the now defunct 4 liter V-8 diesel both have 72 degree V angles so it is safe to assume that they were produced on the same assembly line. This narrow angle is sub-optimal for low NVH (noise vibration and harshness) so the counter-balance shafts are required to reduce NVH. The choice of this narrow angle is most likely commercial, a compromise to make the engine fit into most MB cars rather than an attempt to create the smoothest and best engine.

The present gasoline V-8 engines all have 90 degree angles. I am unsure what angle the V-6 3.5 liter engines have.

Is the Kubota not a snow plow vehicle? I saw one doing my street last week.

Kubota is a Tractor! Mine has heated cab with CD player and lots of lights.

Other pic is my 95 E300D and new (to me) 06 E320 CDI.

Nice Kubota. The City of Toronto snow plow I saw looked the same but of a different color and it has no CD player. The operator told me his machine has 80 horses.

Did someone steal your wheels or are you putting new rubber on? Mine is brilliant silver too. This is the most popular color and therefore easiest to sell.

Is the 1995 diesel a non-turbo?

The Kubota is a 2006 B3030HSD. 30HP Diesel, though big horses. The 80HP unit in Toronto had to be huge - these tractors don't have large HP numbers.

Color on the CDI is actually Pewter - more of a dark silver/gray. Photo was in October - I was installing Michelin X-ICE 2s... excellent tire - smooth up to 120 MPH so far when taking my dad to the airport - I had him look at speedo, and he thought we were only doing 70 at the time.

The other car is 1995 E300D with the bulletproof OM606 non-turbo motor. Only has 120,000 and is going strong. When the heavy snow comes, the CDI stays in garage, and the 95 is my snowmobile. Dunlop Graspics make for very predictable snows, and the car loves to do endless broadslides - very controllable. Much more fun to play in snow with it rather than turn off the traction control on CDI. The 95 feels more naturally balanced when sliding.

But when the snow goes away, WHOOSH goes the CDI.

E320 cdi 06
fuel mileage improving

My brother has same car E320 cdi 06' with a 40,000 more miles and was regularly getting over 42mpg highway, in past few months after I passed the 150,000 miles, and am regularly seeing over 41 mpg.

My guess is the engine has finally broken into correct specs?

I6 Vs V6

I test drove the 2005 CDi I6. Very impressive

I have not test drove the V6 yet.

On the 05 it has the SBC break system. In the US you cannot buy the 05-06 without it. This makes me gun shy to pull the trigger.

I know were talking about the V6 vs the I6 but how should I weigh the negativity of the SBC system

Go for the I6 and shop around for an extended warantee

Nothing wrong with the SBC system. More advanced system then what replaced it. The SBC is under 10year warranty too. Suspension is another matter. 7+ years later I still love my 06 e320 CDI with the I6. Unfortunately I haven't even put 70k on it. Make sure the suspension is in good shape along with the brake pads and rotors and you will be fine.
