I have the inside that the new c class will look similar to the 07 s class and have a panoroof. Im ordering it with the new bluetech engine for 08 very excited. Anticipate the car hitting the shores In Late Feb or March. I have actually seen the car with my own eyes. So I know you wont be dissapointed. JJ

Are you serious? A C class sold in USA with a Bluetech diesel???? If this is true that is the best MB diesel news I've heard all year!!!

oilbelcher

which diesel engine will be used in the C class? the new 3 liter v6 used in the E320 CDI, or one of the smaller diesels used in Europe by MB?

The 2008 C class will be available in early 2007? for delivery when?

I thought that you could not buy a NEW diesel car in CA, you had to buy it used (designated with at least 7k miles)...does this change with Bluetech technology?

240D 3.0T

I feel a chain yanking.

The C-class won't have a diesel next year. Only the E, ML, GL, and R will get the 3.2L V6 diesel option. Even still, CA won't get ANY new diesels from MB.

EDIT: From MBusa.com "The 2007 E320 BLUETEC, ML320 CDI, and R320 CDI do not meet the emissions requirements of California, Maine, Massachusetts, New York, or Vermont and are not available in these states."

"**The E320 CDI Sedan does not meet the emissions requirements of California, Maine, Massachusetts, New York or Vermont and is not available in these states."

The only sedan to get the CDI in 2007 is the E320CDI.

jjay911 said "2008", not 2007. You're correct for 2007, but who knows what 2008 will bring?

Don't think so, JJ. It still has to go through the European launch and introduction, and we would've seen spyphotos of finished pre-production cars by now if that was imminent.

Also, while I'd love to believe that the new C will look like the S with its bulging fenders, prototypes show a conventional flat side like the current car.

I don't doubt it will have a Pano roof and Bluetec, but the 2008 C-class won't be "hitting the shores" for at least a year.

Did anyone see the posting of this documentation? I must have missed it.

It was not 59 mpg, it was 49. An impressive feat nonetheless.

The article is here:

http://www.aluminum.org/ANTemplate.c...ContentID=8774

These results, of course, may never be duplicated by normal drivers. It was just a way for MB to show off the potential economy for the new 300 CDI (Its actually a 3.0 liter V6, not a 3.2).

DslBnz

I read that article again. Every other credible source I have read specify a 35 mpg highway estimate, not 41. At least the recent one's such as the Star magazine. Imperial mpg numbers would be about 41, however.

I dislike inconsistency. If there is a boast, I'd prefer it to be credited from other reputable sources as well.

Wolfgang

That would be lower than the 2006 E320 CDI.

That's interesting. Thank you for sharing that with me.

However, I don't know how the EU4 E320 CDI with the OM642 stacks up against the bluetech version. The EU4 CDI, sold in Europe right now, has 221 hp and 376 lb/ft of torque. The Bluetech version we get has 208 hp and 398 lb/ft of torque.

Here's the chart from Europe. The OM642, without the strangling of bluetech, and the automatic 7G:

Even Mercedes has specs that conflict with it's sister sites, published for all to see.

How can Bluetech: a system that increases backpressure and reduces power output, actually increase mileage by almost 17%?

BTW, don't mean to sound like an ****.

Wolfgang

Careful, the torque on both sites you link for the E320 CDI (EURO4) is given as 540 Nm which is 398 lb-ft.

Ah, did we discover the "diesel paradox"?

Don't get too hung up on the 17% as it's just the current dataset and might change before it's actually posted on the cars sold at the dealerships. Also, it's comparing two different engines, the OM648 DE32 LA inline six with the 5 speed and the OM642 DE30 LA with 7 speed.

It might make more sense to compare the fuel economy to the E320 CDI (EURO 4) on the German site. Since MB introduced particle filters as standard around October 2003, the consumption figures there should include the particle filter. The major difference to the E320 Bluetec is simply the DeNOx catalytic converter, which shouldn't influence it too much. However the numbers on the German site are given for the European test cycle instead the of the test cycle required by the EPA on these shores, so are not directly comparable.

DslBnz

Dagnabit, you're right!

I could've sworn it was 376 lb/ft! Didn't it used to be... Before EU4? The OM642 statistical outputs posted online seem a little too dynamic in relevance to MBUSA's claims.

In regards to restriction, if the DeNOx cat will not add any significant backpressure, why is the output on the Bluetech down 13 hp? Since it retains the 540 nM, yet has 13 less horsepower, that may translate into a lower peak horsepower engine speed, and a narrower torque band. But not by much.

I wonder what differences in testing there are between the EPA and European test cycles.

Wolfgang

In addition to what we mentioned the different peak horsepower might also be due to different engine tuning by Mercedes, maybe for more fuel economy instead of power for this particular model - just a guess, until we have more data like zero to 60 times etc. Also, when looking up the specs for other vehicles which are to use this same engine, like the Dodge Sprinter, Jeep Grand Cherokee CRD, Freightliner Sprinter, ML280 CDI, ML320 CDI, R320 CDI, GL320 CDI the peak horsepower usually differs a bit depending on the particular application.....
