Does anybody know if this model will be available at initial introduction of the W212? From what I've read, it looks like the initial BlueTEC's might not come with the "Add Blue" feature. Anybody know about that? I'm curious because I'm interested in the car and am wondering if one will have to sacrifice the spare tire for the liquid as is done on the SUV's. I would not like a car with "run flat" tires to compensate for this. Hopefully they can find a spot to tuck in a tank for the urea other than the spare well.

The definition of a BlueTEC is that it has the urea solution, hence the difference between a CDI and a BlueTEC..

As to production plans, it's all speculative at this point

From what I hear, the new W212 USA Bluetec model will in fact use the Adblue system. It is supposed to be available a few months after the introduction of the W212. As for the spare, not sure but if the logic is the same as the SUVs then probably no spare and run-flats. Hope I am wrong on that one.

Polar Bear

Sorry - that is incorrect. The Bluetec W211s have never had urea injection. They use an SCR catalyst for NOx reduction.

Polar Bear

I hope you are wrong too. I would not be interested in the AdBlue system. It tips the scales for me in favor of the gas engine vs. Diesel.

BlueTec by definition has AdBlue. And AdBlue works with SCR in tandem (SCR doesn't reduce NOx on its own w/o AdBlue). But I was told by MB service advisors some early BlueTecs the AdBlue is under the seats so it can only be refilled by dealers or garage. New BlueTecs the tank is in the spare tire so you can refill yourself.

TMAllison

As was pointed out previously, in the USA at least, that is incorrect. See E320's 07-08.

Diesel Benz

By definition it may have AdBlue but in real life it does not. Please do not make assumptions and post "facts", it is very confusing (and impolite for those like Polar Bear who know what they post, TMAllison also knows but his post was not yet "challenged" unfairly).

I'm sorry if I am not polite, but one should really add a comment like "as far as I know" at least in a case like this in order to avoid confusion.

Actually I have not figured out which current models would use AdBlue but definitely not all so far do.

"As to production plans, it's all speculative at this point."

This is also FALSE information. Both W204 and W211 BlueTEC cars are delivered overhere in Europe as we speak. The USA are not the center of the automotive world for MB... In fact MB produces more Diesel than petrol cars and that market is overhere.

For USA, it goes something like this:
Current Offerings - USA diesel:
MY09 W211 E320 BT - no adblue system; denox catalyst but not 50 state legal

MY09 ML/R/GL 320 BT - adblue system; 50 state legal

MY10 E320 BT - adblue system; 50 state legal

Adblue tank in all US versions is in the spare tire well - hence, no spare and runflats.

Also, on a positive note, the US 212 diesel will apparently be available as a sport model.

I don't think you are right about the W211. The E320 Bluetec was first introduced in the US it does not/did not have AdBlue. The same vehicle was later introduced in the EU and again, did not have the AdBlue. The W212 BlueTec will have AdBlue worldwide.

See this link discussing the introduction of the W211 E320 Bluetec.

That's really too bad. I am all for the environment, but I don't like the additional complexity of the AdBlue system. Since Mercedes-Benz is one of the leaders in Diesel technology, let's hope they develop a system that will not require the additive to meet the emissions requirements. I love Diesel technology and have owned three MB Diesels, but have really lost interested with the BlueTecs and the AdBlue additive. I think my next Mercedes product will be a pre-AdBlue model or a gas model.

pmb600

The AdBlue system isn't so bad. You simply have it refilled at every oil change which is only 10,000 miles or 1 year.

Polar Bear

True, but it just seems to me as one additional thing to worry about. Especially after being spoiled with the current technology that does not require AdBlue. The Jetta TDI does not need this technology. I know it doesn't have the power or the displacement, but I just feel this is a bridge technology and that it will not be required in a few years once more research is done.

Unfortunately, Diesel is a hard sell for many people in the US anyway, and when you try to tell folks that that the Diesel does not have a spare tire, has AdBlue additive and will need to be filled, and that the vehicle would not start after it if it runs empty (I know there is plenty of notice before this happens), but when you start telling people about these items that are typically perceived as negative characteristics, I don't think most people will really consider the technology. The BMW folks are not really happy with the run-flat tires that are coming on them, so I personally feel this is also another negative feature.

Diesel technology has always been perceived by Diesel enthusiasts as being simpler than their gasoline counterparts, but now with the additional emissions complexity this doesn't seem to be the case. I would probably opt for an E550 or C63 if the AdBlue continues, or hang on to my E320 CDI. With Direct-Injection gasoline engines soon to be available in the US from what I hear, this will start closing the gap - at least enough for me to abandon Diesel technology with AdBlue.

Diesel Benz

The link did not talk about the W212. EPC now starts to cover the European W212 E350 BlueTEC and I cannot find any urea injection parts, where should those appear (EPC section or in the car).

All W212 diesel models are Euro 5 compliant, including the E350 BlueTEC.

Run flat tires on the 2010 E-class diesel sedan would be a deal breaker for me.

wdlanning

When will the new diesel be available in the states?

Diesel Benz

Me too, I might not buy a car with run flat tyres, spoils the tyre performance.

Luckily one can shop tyres from a tyre shop, which ever fit the owner's personal preferences.

ben721364

Run flat itres (current iterations at least) not only porvide less road feel, they are noisy to the point of being embarrassing and can be difficult to find in smaller cities. I ceased being a loyal BMW customer after 35+ years over run flat tires after owning two such cars.

While it's true enough as you noted, to replace run flats with conventional tires, the spare poses another problem. Rumor has it that when the diesel engine is made available, the spare tire well will host the urea tank. If so, no dice for me...

shoes

The latest theory postulated by my local dealer is that the E-Class is selling much slower than expected across the board and Mercedes wants to sell through more of the existing inventory before introducing the diesel variant in the US. I am tired of waiting for a model announced more than one year ago and will buy a VW Golf diesel instead. The rumors of mandatory run flat tires only seal the decision for me.

ben721364

Me too! I owned two cars with run flop tires and don't intend to own another until/unless they are vastly improved. They did not provide road 'feel' and were embarrassingly noisy after about 10,000 miles.

Polar Bear

Although I expect urea injection to be a part of the E320 in the US, I sure hope that is not the case. If it is, I will have to skip on that one too.

It also really bothers me that they remove some nice options from the V6 models in the US - dynamic seating, etc.

pmb600

Sorry to hear that, hope you will wait for the E350 Bluetec. The car was always scheduled for a Spring 2010 introduction from what I understand.

Be careful what you believe from one dealer, a lot of times they will tell you anything...the new E-Class is selling very well from what I have seen.

pmb600

The Drive Dynamic Driver Seat is available in the U.S.

To my knowledge the launch date has not been pushed back. It is still scheduled for Juyl of this summer as a 2011 model. However, there has been no mention of run flats or urea injection on the sedan's.
