E-Class (W212/S212/C207/A207) [Official] Mercedes-Benz E-Class (W212) Facelift

[Kilcrohane]

Autozeitung compared the E 350 BlueTEC with 9G with the 530d. The 9G is doing okay, but probably not worth waiting for. Just reduces the rpms on the highway somewhat.

CONCLUSION
The benefits of the wider gear spread of the 9G-Tronic in comparison with the seven-speed box mainly result in lower rpm levels on the motorways and thus benefit the fuel consumption.

and also helps the Mercedes V6 diesel engine close the gap to the fuel efficiency of the BMW I6 diesel, with just 0.1 litre/100km fuel consumption difference on test.

I have a feeling the Mercedes engineers will really put their efforts into the revised CLS- and M-Class, for the 9-speed auto to shine.

Just closing the gap with a gearbox/car that has been on the market for many years is not what I call impressive.

Particularly when ZF is not standing still either. Their next effort will not be 'on par' with the old 8 speed, it will be a significant improvement.

'So gut ist die Neungang-Automatik'

Maybe Auto Bild rushed to as usual slate a new Merc, and Auto Zeitung were fence-sitting, but AMuS seem to have found little trouble praising the new 9-speed and the overall car - the E350 Bluetec. Maybe it's not so 'bad' after all.

 

[klier]

So good compared to what? Their old 7 speed?

Looks like the latest reviews confirm the 9G-Tronic is delivering as promised.


Perfect interaction: E 350 BlueTEC with V6 diesel engine and 9G-TRONIC

On the one hand, the overall reduction in engine speed improves NVH comfort and therefore the pleasant sense of well-being on board the E-Class, and on the other also cuts down external noise by up to 4 dB(A), thus reducing the strain on the environment. The reduced fuel consumption of the E 350 BlueTEC with 9G-TRONIC has primarily been achieved as a result of the high efficiency level of the transmission. As part of this, the broad ratio spread of 9.15 for gears one to nine allows a clearly perceptible reduction in engine speed and is a decisive factor behind the high level of energy efficiency and ride comfort. Shortened shift and reaction times ensure optimum spontaneity combined with outstanding ease of shifting. In manual mode and S mode in particular, the 9G-TRONIC responds significantly more spontaneously and enhances driving pleasure.

The particular ease of shifting of the new 9G-TRONIC - a focal point during development and a hallmark feature of a Mercedes-Benz automatic transmission - comes courtesy of a comprehensive package of measures. These include the novel direct control system which enables short, barely perceptible gear changes. The combination of twin-turbine torsional damper and centrifugal pendulum technology in the torque converter ensures outstanding drive comfort. Together with the extended gear ratio spread, higher speeds can now be driven at lower engine speeds for even greater comfort. In reality this translates into being able to drive at 120 km/h in 9th gear with an engine speed of around only 1350 rpm, for example.

It's SO GUT but still sehr schlecht compared to BMW+8HP.
Sehr beeindruckend!

Good news for BMW

PS: I had no time to read the whole thing as I'm going out.
Will check that 8HP thing later.

Not what you said a few days ago - "Autozeitung compared the E 350 BlueTEC with 9G with the 530d. The 9G is doing okay, but probably not worth waiting for"

 

[Wolfgang]

^ Still think both statements apply. Delivered as promised, and probably not worth waiting for. The fuel economy improved about 3.7% or so, but is already very good in the E-Class diesels.
Here's some data taken from MBUSA using the 7G. The E250 BlueTEC with the 9G might get rated as 29/47 MPG, instead of the 28/45 MPG at present -- not that much of a difference IMHO.

[Serpens]

I think people here are more concerned about shift quality/programming than strict fuel economy savings. We want to MB to produce a tranny that can beat or at the very least match the ZF 8-speed.

@Kilcrohane seems to be able to read German as well......take a look, ZF 8 speed 2.0.
Like I said, the competition is not standing still.

Thanks to @Wolfgang for being honest and open
You're real Guru, bravo. I'd be happy with half of the class you have.

Exactly!

@klier
Yes, Wolfgang is a really cool guy

 

[-=Hot|Ice=-]

So did BMW with Getrag for M-DCT. And just like BMW, Porsche is also using the ZF 8 speed where it is applicable. That is what smart companies do. It is almost criminally stupid not to use a better part that can be brought off the shelf, but instead use a sub par one just cause it was developed internally.

As an aside, I face similar situation almost every week - dumb ass old school companies that want to run their own servers and networks instead of leveraging the cloud services, because somehow having a server in your basement gives them warm fuzzy feelings. ****ing morons! /rant.

Don't want to go off topic, but as good as cloud servers are, some people like to be able to physically touch something.They like seeing where the data is going and being stored.The cloud is relatively new, businesses will eventually warm up to them. I'm studying IT and Business, and actually am finishing up my Business Communication class.

Time will tell. Next model to receive the 9G-Tronic is rumored to be the CLS, with some engines, around October, in the version without 4Matic.

Don't want to keep the off topic going, so I will hide it.

Spoiler: Off Topic

Yes, lot of people have feel good in keeping the data physically in their control. But it is just one of those uncorroborated feel good factors. The fact is data centers belonging to a well run cloud service like Amazon web services is many factors more secure both physically and electronically than than what the vast majority people or even other companies can efficiently implement.

And congrats and good luck with your classes.

Wolf, why is there a light inside a headlight? Please don't tell me that's actually going to be on a car. That's hideous. Mercedes has gotten the headlights perfect. Tell them not to ruin it!

 

[Wolfgang]

-=Hot|Ice=-, agreed. Suspect that's just a teaser for the new Active Multibeam LEDs expected to debut in 2014.

Active Multibeam LED extends the existing system with a new dimension. Until now are the functionalities, like active curve illumination or adaptive highbeam assist are mechanical operated. With active multibeam LED the Engineers can operate each single LED seperately and so illuminate precisely certain areas and blend out very precise other areas.

The system operates in conjunction with the stereo camera.

With Active Multibeam LED the lights can respond more quickly and more individual to changing trafficsituations. New functions like foreseeing curve recognition are possible as well.

Don't agree, i.e., it is worth waiting for, and will make a marked difference, especially for high-speed route users in Europe and in the U.S., where in some states speed limits are edging up.

Why? Because the 9G's top overdrive ratio is 0.60, compared to the 7G's 0.73. That's a 18% difference.

When travelling in top, 9th gear on a German autobahn or US highway, at typically 80-85 mph, that means a large reduction of engine speed, from around 2,200 to 1,850 revs/min.

Because the US EPA fuel economy ratings are far more real-world than the European NEDC ones, we can expect to see at least the Highway ratings jump up significantly, by far more than 3-4%. I would be surprised if the Highway ratings for 9G-equipped cars did not increase by at least 10%.

 

[Mick Briesgau]

I'd like to emphasize another aspect of the new 9G automatic and that's a typical MB aspect; Comfort. As far as I understand the different testreports in German Magazines, the sleekness and smoothness has improved significantly. You don't even notice there's a gearchange at all.
