E320 CDI vs. E320 BLUETEC
Forget politics and onto good news. Audi is bringing in a diesel A8 to the USA as a 2013 model and BMW is doing a M5 sedan diesel car with a tri-turbo. The former is rumored to be 245 - 313 bhp! I am sure this TDI engine will filter down to the A6 eventually, to compete with the MB Bluetec. If so, MB would have to boost the miserly 240 bhp higher, much higher and put in a 4Matic, to compete with Audi. The consumer wins again.

Internet stories about the US losing refining capacity aren't true. I've been following the oil industry peripherally and they have been slowly expanding their refining capacity by both increasing the output of refineries and adding new ones (when the government and local rules allow I suppose).

The Best of Mercedes & AMG
I am temporary in Evrope and I am so envy what kind of car I can see it here (MB, BMW, Audi,...all diesel)
I agree - Volvo diesel would be very high on my list

Before buying this E320, I was waiting for an Audi A6 or A8 diesel or a BMW 5 diesel... neither materialized here so another E it is. Wish the other mfg's would start selling them here... I love my MB but competition is always good.




* Big Oil has kept good technology away for many years
* Big Oil keeps the rumor mill grinding to keep Bio fuels off the shelf
* Change your fuel source to locally produced fuels or make it yourself with a co-op if you can.
* Change your politicians to those looking out 15-20 years, when the current products are about gone.
* Buy a centrifuge and a few books on producing bio fuels and supplement your current fuel.
* Diesels are great clean engines, however they are only provided "byproduct" fuel at the USA pumps
* 880 Las Vegas School buses all run on non Dino Diesel
Research the need for Catalyzed particulates and test your vehicle without one, off highway of course. Third world countries thrive with our old technologies.
Convert your muscle cars fuel systems to alcohol mine run better cleaner cooler and faster with an E85 blend, no longer need 105 octane. Sunday cars..
Wake up Americans, these Big Oil supporters are not our friends. Germany does not tax bio fuels to encourage the use by consumers. So your car will run on it safely the German pumps prove it.
Change your fuel supplier and pay your highway fuel tax.

What are you doing for fuel for your CDI?

DPF? __ __ Partic. filter?

Are you not that familiar with your CDI?

In North America, CDIs are only used in the 2005-2006 model years and they do not have DPFs
That is one of the reasons that makes the '05 and '06 MYs the models of choice IMHO!
One could not use high percentages of biodiesel IF they had either.
AND the DPFs used beginning in 2007 are an exhaust restriction to boot.
That is probably one of the reasons that the 648.961 motor
'puts out' so much better than the later V6s.
Sounds to me like those who are using biodiesel have not done anything
to modify their CDIs other than simply putting bio. into their tanks.
I have run B10 in mine, but not regularly as I believe that in so doing, I lose fuel economy.
Your mileage may vary.

I saved enough money on fuel to pay for the used engine. But not worth the effort.

You've got the first point right, but the last two points are completely WRONG.

The V6 does not and can not smoke because of the DPF.
As far as their performances being equal? In what manner?
Fuel economy? No way! Compare the Fuelly entries for both models.
Quarter mile or 0-60 times? The 648.961 straight six has the edge there also.
Dyno readings? Check mine out below in my signature.
Ask yourself how a motor with only 3 liters can put out more than one with 3.222 Liters.
I rest my case.

It's funny, on every single mercedes forum, the only people that talk trash about the V6 are I6 owners. It's almost like you have to justify your purchase to yourself.... Good for you, keep on smokin there Mr Greenie.

I have never driven the V-6 Diesel.
My ideal motor would be an I6 diesel with 4 valve heads, with 6 exhaust valves on each side and 6 intakes on each side, alternating. This would make a more even temperature range. It would have twin turbo's and twin intercoolers. The left side would blow into the right side bank and the reverse.
I am sure that the V-6 was designed for packaging Not for better engineering. But that is the world we live in.
I-6 has slightly more hp, V6 has slightly more torque. V6 is lighter and has the 7-speed. The V6 will win every race.
If only both cars were a little more common, perhaps I'd see one at a stoplight one day to find out.

Several things you say are not correct!
First off, I am from Missouri (the show me state!) not true, as I
am a Californian but 'show me' these figures and the sources.
You are wrong when you say the I-6 has more advertised horsepower. It does not.
Also, MBZ quotes the V6 having more torque, but it does not!
My I-6 does have more torque than MBZ quotes. By at least 15 ft/lb. to the wheels.
And more horsepower too; 211 hp vs the advertised 201 hp.
The 5G transmission is the trans of choice, although I wise I had the 10 percent higher
overall gear ratio that the 7G tranny provides over my five speed.
Many people have complained about how the seven speed trannies (the 7G) are not programmed
properly to the diesel engines and hold the gears too long.
Ask yourself why the S65 the CL65 and the SL65 vehicles still use the
5G transmission? It is because the 5G is the stronger and simplier transmission.
One of the reason many of the CDI I-6 owners talk about their vehicles is because we all know them
to be far superior to the later cars that MBZ brought here beginning with the 2007 V6 cars.
We will agree that the V6 engine is lighter (it is after all, all aluminum!) so why is the 2007 listed
as being heavier than the 2005-2006 CDI I-6 that has a cast iron block?
Could it be that the seven speed trans is heavier than the old five speed transmission?
I want to see some times for the later V6 diesels at the drags before
I will agree that they are faster or quicker than the I-6 CDIs.

As far as fuel economy is concerned, do a comparison for the Fuelly entries for the 2005-2006
CDIs in North America vs the 2007 and later 3.0 liter V6 for North America.
The I-6 blows the V6 away and their fuel economy is not even close.
One of the reason is that their DPF chokes off the exhaust.
Our I-6 CDIs do not require that, so they do breath better.
The same thing happens when comparing the 2007 and later PU diesels with the older models.
I am going to Irwindale tomorrow. Perhaps there will be a V6 diesel there?
