LOL, that's what I'm saying! Selfishly, I hope it's not that great an improvement. Don't want to start feeling remorse for my car. I do wish M-B implemented the new drivetrain when this car launched, but at the same time, there's something solid and proven about having a brand new body car, with a tried and true drivetrain.
Anyway, HP and performance is very low on my list of "cares" for this car, so I'm in a good place, although, I certainly wouldn't mind it. My big curiosities and cares are smoothness, and although MPG isn't a big factor either, I sure would like some better.

fwiw, the official Daimler press release has been out for several days....
The E in E Class now stands for "Efficiency." And they're using "Blue" now with everything not just as in "BlueTEC" diesels....
And a "new improved" 7GTronic Plus tranny... with "Eco" stop and go.
When Weber said he didn't want to ever pay any more CAFE fines, I guess he meant it...
All specs are Euro. Info about the 4 cylinder E Class models and manual transmission models deleted for brevity....

New engines for the E-Class: E-Class more efficient than ever
With V6 and V8 petrol engines that consume up to 20 percent less fuel, Mercedes-Benz is once again raising the measuring standard for efficiency in the E-Class segment. For example the E 350 BlueEFFICIENCY with a V6 engine has a low NEDC consumption of 6.8-7.0 litres of premium petrol per 100 kilometres. This corresponds to CO2‑emissions of 159-164 g/km. The combined consumption of the new V8 model E 500 BlueEFFICIENCY has fallen by 17 percent to 8.9 l/100 km (209 g/km CO2)*. All** petrol and diesel engines in the E-Class now have direct injection. The leap in efficiency achieved with the BlueDIRECT engines is supported by the ECO start/stop function, which is also standard equipment for the four-cylinder models in future. In addition all automatic versions** are equipped with the improved 7G-TRONIC PLUS 7-speed automatic transmission, which likewise contributes to fuel economy.
"The new BlueDIRECT V6 and V8 engines set previously unattained standards in the luxury class," says Dr. Thomas Weber, the member of the Daimler AG Executive Board responsible for corporate research and development at Mercedes-Benz Cars. "With the new V6 engine in the E 350 BlueEFFICIENCY we are able to realise fuel consumption figures previously only possible for four-cylinder units. To remain at the very peak in the automotive executive class, however, Mercedes-Benz is not restricting itself to the introduction of highly efficient engines, but also using every conceivable means of saving fuel – from aerodynamics to lightweight construction, and from optimised transmissions right up to the electrification of the powertrain and peripheral units."
BlueDIRECT: the most efficient form of direct petrol injection
The two BlueDIRECT petrol engines in the E 350 BlueEFFICIENCY and E 500 BlueEFFICIENCY represent the new generation of V6 and V8 engines, which celebrated its world premiere in the S-Class and in the CL. The centrepiece of the BlueDIRECT technology package is third-generation direct petrol injection with spray-guided combustion and an injection pressure of 200 bar. Major features:
1) The Multi-Spark Ignition (MSI) system, which enables up to four sparks to be triggered in rapid succession within one millisecond
2) Latest-generation piezo injectors for up to five injections per power stroke
3) Stratified combustion is extended with a newly developed lean-burn process ("Homogeneous Stratified"), which greatly widens the characteristic map for fuel-efficient lean-burn combustion in the V6 engine. The first fuel spray is injected on the intake stroke, whereupon a homogeneous basic mixture is formed. The actual "stratified" injection takes place on the compression stroke prior to ignition, and is map-dependently controlled in the form of a single or double injection.
E 350 BlueEFFICIENCY: the most fuel-efficient petrol model in its class
The 3.5-litre V6 engine of the E 350 BlueEFFICIENCY is naturally aspirated. As a major distinction from the preceding engine, the V-angle between the cylinder banks has been reduced from 90 degrees to 60 degrees. This has enabled the balancer shaft compensating primary vibrations to be omitted. As a result the driver notices an outstanding level of comfort. Another feature is the completely new air intake system with a variable-resonance intake manifold. The wealth of innovations has a positive effect on both performance and fuel consumption: with the same displacement, the output of the E 350 BlueEFFICIENCY has increased from 215 kW (292 hp) to 225 kW (306 hp), with maximum torque increased to 370 newton metres (previously 365 Nm) and available over a wide engine speed range from 3500 to 5250 rpm.
At the same time Mercedes engineers have achieved a remarkable reduction in fuel consumption. The NEDC consumption of the preceding model (8.5 litres of premium petrol per 100 kilometres) has been reduced by one fifth. The new V6 petrol engine of the E 350 BlueEFFICIENCY consumes only 6.8-7.0 l/100 km (E 350 4MATIC BlueEFFICIENCY: 7.4-7.5 l/100km)*. This corresponds to a saving of 1.7 litres or 20 percent, and makes the E 350 BlueEFFICIENCY the most fuel-efficient petrol model in its performance class. CO2 emissions have likewise fallen by 20 percent, from 199 to 159-164 g/km (E 350 4MATIC BlueEFFICIENCY: 174-176 g CO2/km)*.
The E 350 BlueEFFICIENCY combines its excellent fuel economy with dynamic performance. Acceleration from zero to 100 km/h takes just 6.3 seconds (E 350 4MATIC BlueEFFICIENCY: 6.6 s)*. Maximum speed is 250 km/h (electronically limited).
E 500 BlueEFFICIENCY
More power with far lower fuel consumption
While the V6 engine is a naturally aspirated unit, the new V8 engine of the E 500 BlueEFFICIENCY for the first time features twin turbocharging, which was previously only familiar from the 12-cylinder S-Class and CL. Despite a significantly smaller displacement (4633 cc, previously 5461 cc), the eight-cylinder has gained in both output (300 kW/408 hp, previously 285 kW/388 hp) and torque (600 Nm, previously 530 Nm). At the same time fuel consumption has fallen by around 17 percent, from 10.8 to 8.9 l/100 kilometres (E 500 4MATIC BlueEFFICIENCY: 9.4 l/100km)*. CO2-emissions have fallen to the same extent, from 253 to 209 g/km (E 500 4MATIC BlueEFFICIENCY: 219 g/km)*. These figures make the new E 500 BlueEFFICIENCY the executive saloon with the lowest fuel consumption in its performance class.
The excellent efficiency goes hand in hand with superior performance: the E 500 BlueEFFICENCY and the E 500 4MATIC BlueEFFICIENCY sprint from zero to 100 km/h in 5.2 seconds. Top speed is 250 km/h (electronically limited).
Both the new V6 and the new V8 from Mercedes-Benz have aluminium crankcases, pistons and cylinder heads. The crankshaft, connecting rods and valves are of special forged steel. Thanks to systematic lightweight design and intensive fine-tuning of details, engine friction has also been reduced by 28 percent compared to the previous engine.

As part of the standard BlueEFFICIENCY package designed to improve efficiency, the engineers also reduced the energy consumption of major ancillary units in all E-Class petrol and diesel models. The luxury saloon therefore has a demand-controlled oil pump operating with two pressure stages. At low engine speeds and loads the pump operates at a low pressure. The high pressure level is only activated at high loads and engine speeds. Especially in urban traffic, this means that the lubrication and cooling points of the engine can be supplied for far less output.
As another special feature of the BlueEFFICIENCY models, the demand-controlled water pump is only activated when the best possible operating temperature has been reached, thereby achieving a faster warm-up and likewise helping to save fuel. There is also energy-saving control of the fuel pump, air conditioning compressor and power steering.
Each time the car is braked, kinetic energy is converted into heat and therefore goes to waste. This is why the E-Class incorporates efficient alternator management. This means that, whenever the engine is coasting and whenever the vehicle is braked, the voltage level in the vehicle electrical system is increased and the battery is charged. This increased alternator load assists the driver with braking and also helps to recuperate part of the braking energy, which is converted into electrical energy. This is why the experts refer to recuperation. Conversely, the alternator switches to no-load operation in certain situations – for example when accelerating or when the battery charge level is high – thus relieving the strain on the drive system.
The BlueEFFICIENCY concept for the E-Class also includes aerodynamic improvements using an automatically controlled fan louver, which regulates the airflow into the engine compartment as required.
ECO start/stop function: standard for four petrol and three diesel engines.
The BlueEFFICIENCY package includes tyres with an up to 17 percent lower rolling resistance and the ECO start/stop function.
ECO start/stop function
In the E 250 BlueEFFICIENCY, E 350 BlueEFFICIENCY and E 500 BlueEFFICIENCY with the 7G-TRONIC PLUS automatic transmission as standard, the ECO start/stop function switches the engine off when the driver brakes the car to a stop and maintains pressure on the brake pedal. The engine restarts immediately when the driver takes his foot off the brake pedal.
High level of comfort and efficiency
Thanks to direct-start technology, the start/stop system developed for petrol engines by Mercedes-Benz works immediately and with low noise: when restarting, fuel is first injected into the cylinder whose piston is in the best possible starting position. The advantage is that after briefly turning the engine over, there is immediate ignition and combustion of the mixture in the best-positioned piston, which improves comfort while avoiding unnecessary fuel consumption and emissions.
Thanks to intelligent control, the heating and entertainment systems remain operating during the stop phase for maximum comfort, as does the automatic climate control. The ECO start/stop function does not switch the engine off if the operating temperature required for proper emission control or the interior temperature desired by the driver have not yet been attained.
Comprehensively improved automatic transmission 7G-TRONIC PLUS
The E-Class with automatic transmission will be equipped exclusively with 7G-TRONIC PLUS. This comprehensively improved 7-speed automatic transmission is standard equipment in the E 250 BlueEFFICIENCY, E 350 BlueEFFICIENCY and E 500 BlueEFFICIENCY. One major feature of the latest evolutionary phase of 7G-TRONIC is a new generation torque converter with a much more dynamic response. Noise and vibration levels have also been reduced thanks to a new hydraulic circuit, improved dampers and a new torque converter lock-up clutch with considerably reduced slip even under low loads. This has enabled Mercedes-Benz developers to lower engine speeds in the fuel-saving ECO transmission mode without compromising comfort.
With low-friction bearings and seals, as well as a new transmission fluid with lower viscosity, the transmission itself also contributes to fuel economy. Thanks to the long service life and unchanged cooling efficiency of the transmission fluid, this now only needs to be replaced every 125,000 kilometres. The transmission's improved electro-hydraulic control unit and new, low-friction materials in various areas, as well as optimised software, lead to improved smoothness. Thanks to a separate, electrically driven transmission fluid pump, which is activated according to demand and allows comfortable, rapid starts, 7G-TRONIC PLUS is also start/stop-capable.
The four-cylinder diesels in the E-Class: considerable increase in efficiency.
Particularly in the four-cylinder variants of the E-Class, the ECO start/stop function and 7G-TRONIC PLUS make for a considerable increase in efficiency. The engine specialists have also optimised the oil pressure control and belt drive, and equipped the turbocharger with a self-regulating compressor.
Comfort and design: perfected in detail
In addition to the new engine/powertrain features, the Mercedes-Benz E-Class now has new interior and exterior details. These include the full-colour TFT display in the instrument cluster, which is also capable of showing three-dimensional graphics. Another new feature is the standard DIRECT-SELECT selector lever for 7G-TRONIC PLUS on the steering column - also in the four-cylinder models. The driver is able to select transmission positions "P", "N", "R" and "D" by nudging a selector on the steering column. The operating commands are transmitted electronically, by cable. The package includes steering wheel gearshift paddles. Another standard feature in the ELEGANCE line is the luxury front head restraint, whose side bolsters can be adjusted as required.
The E in E Class now stands for "Efficiency." And they're using "Blue" now with everything not just as in "BlueTEC" diesels....

I'm vigorously opposed to any "start/stop" feature in any car *I* own.Too much can go wrong plus it would be a pain in the a**.I'll happily drive a diesel...one that gets 40mpg highway...and thus save substantial amounts of oil but "stop/start" is total BS.The trust funded tree worshipers of Sacramanto can kiss my hindquarters!

We all better get used to stop and go technology because it will soon be legislated,first by cities and then states. Look to California to lead the way. Personally I agree with the concept of high tech green fuel efficiency.

I doubt it will ever be legislated. What is being legislated is better and cleaner fuel economy. The manufacturers are the ones who came up with start/stop as way of shaving off the numbers in order to fall within the CAFE rules. And if the mfgs like it (because it's cost effective for them to implement), then the mfgs will use it. In the meantime, expect all sorts of technological attempts by them now and in the future......

Great.Then perhaps it can be made optional and you can order it,pay for it and use it if you wish.As I said...I drive a diesel which gets something like 40mpg on the highway so I'll wager that I'm polluting less,per mile,than most cars on the road today...very possible a lot less.If it's ever legislated and I have no choice but to buy a car with it I'll find a way to disable it.

Good discussion guys. Thanks.
Being the glass-half-empty kinda' guy I am, I am more than a little queasy considering the odds of not being annoyed by the restarting process when my next car's engine completely shuts down when I come to a stop and keep the brake applied. I dunno.
".....the start/stop system developed for petrol engines by Mercedes-Benz works immediately and with low noise....."
Frankly, any noise or other startup sensation at all is undesirable, IMO, especially in heavy stop and go traffic, where brief, full stops are frequent.
Looks like you could conceivably defeat this "eco-friendly feature" by temporarily setting your A/C to a much lower temperature than you'd like, which would force the motor to stay on until the cabin reaches that temperature. Not exactly a practical workaround in cold wx.
Or perhaps we can get used to anything after a while.
Progress? I dunno. Let's hope the new system turns out to be seamless afterall.

Good discussion guys. Thanks.
Being the glass-half-empty kinda' guy I am, I am more than a little queasy considering the odds of not being annoyed by the restarting process when my next car's engine completely shuts down when I come to a stop and keep the brake applied. I dunno.
".....the start/stop system developed for petrol engines by Mercedes-Benz works immediately and with low noise....."
Frankly, any noise or other startup sensation at all is undesirable, IMO, especially in heavy stop and go traffic, where brief, full stops are frequent.
Looks like you could conceivably defeat this "eco-friendly feature" by temporarily setting your A/C to a much lower temperature than you'd like, which would force the motor to stay on until the cabin reaches that temperature. Not exactly a practical workaround in cold wx.
Or perhaps we can get used to anything after a while.
Progress? I dunno. Let's hope the new system turns out to be seamless afterall.

btw, it is only operable while in C mode. In S Mode there is no start/stop. The only thing is that you have to set it back to S mode each time after you shut off the car since C mode is the default mode. There are times when a car needs to be running while stopped.
fwiw, it's also been on Toyotas in Japan for a while now. Even Euro VWs and Citroens had it over ten years ago. Having start/stop just means auto mfgs can list the car as having reduced mpg and emissions to comply to stricter rules when the car is sold to the consumer.
It's an easy way to do things for mfgs:
"As far as the green race goes, stop-start is a no-brainer: it's not all that expensive to implement – especially compared to technologies like hybrid powertrains – and according to Ford, it can result in a jump in fuel economy of up to 10 percent."
And don't blame California. This greening of car fleets comes primarily from Europe.... "Stop-start technology has become an easy and effective way for automakers to register substantial economy gains in European models, but don't expect official mile per gallon figures to budge much on America's EPA-mandated test cycle. As of yet, the U.S. government's testing methodology simply doesn't reflect the benefits of stop-start, so while the effects of the technology may be self-evident in real world driving, they won't necessarily be reflected on a vehicle's window sticker in dealer showrooms."

The only annoying trait of the transmission is the jerky start after putting the car in reverse - like during a 3-point turn. I can never understand why.

I agree about the usefulness of the paddle shifters. I would have been fine without them and honestly don't get the need for them in this type of vehicle. I find the current 7 speed tranny to be damn near perfect for the car, especially so with the Diesel (low revs and lots of 'em). That the new version could be better is very good to know. It gives me something to look forward to in the future. I am content with the existing setup in my car. Nothing in the new ones (color display, improved 7 speed, is making me want to upgrade. Now, if they would bring the E250 bluetec here with it's 50+ mpg, or a 4matic diesel, now, that would get my attention. All of these improvements seem incremental to me, evolutionary not revolutionary. My sister has a subaru outback with the Stop/Start, and it is completely unobtrusive. The things we MB owners find to fret about.....

Start/Stop seems like it would be a nightmare, but I'm sure a brand like M-B (and many other brands) will engineer it to be virtually undetectable.

I find the paddle shifters useful for downshifting and passing for highway driving. Gets me from 60mph to 85 much quicker than gas alone. Regards. Ned.

No comparison in reliability between the W212 and F10.
F10 has a lot of documented and consistent problems, and the pre-9/10 models are known to be "avoided at all costs".
Aside from obvious occasional issues here and there, the W212 has been rock solid since its launch, far more reliable and less fussy on a grand scale than the F10. This is from anecdotal research, and reputable "data sources", who rank the W212 and M-B brand as far ahead of BMW in reliability and initial quality.

2014 E350 also restored: 1969 Camaro convertible SS 1957 Chevy Belair 2dr hardtop
I have a 2014 e350 with the 7 speed trans and it is a piece of garbage. There is a jerk between 2nd and 3rd and between 5th and 6th. I have brought it in several times and it still continues to do it. Not a very smooth transmission. I have driven a 2014 e350 loaner and it does not do this. I guess that only some of them have the jerking problem and I know MB is aware of the problem but they have no idea on how to fix it. I just live with it.

2014 E550-sold 😩
Drive it harder and put more than 1,500 miles on it in a year. Seriously, you need to exercise everything in your car, including the transmission. You're a car guy! Put some mileage on it! There is nothing wrong with this transmission.

What's amazing is how Mercedes still uses the 7G which has the same issues as it did when it came out near my 2006 example. Even Benz aficionados have admitted it's a "POS". And when you factor in how old it is and how even when it came out it wasn't considered near an industry standard, it doesn't bode very well.
Is the 9G not gonna make it into any W212 E350? Or have they started putting them in now? Though I've heard the 9G isn't much better or different from some on the forums.

Yes, funny how things change. Much like M-B's quality plummeting via the same research source and I believe BMW's either passing it, or moving up very closely to it. Though that likely has nothing to do with the W212 as I assume being it's been changed only very extensively aesthetically, it's still pretty rock solid. Has more to do with the initial quality more or less disasters of the S/GLA/CLA/C.

We all have fun or not so fun here talking about cars. But that attitude displayed in that video proved a "real life" revelation, which is unfortunate.I actually don't can't get into the S Coupe too much, personally, haha. But it has its moments and angles. I can't quite wrap my brain around what they were thinking with the rear.
Idk, Mercedes just moved to a style I'm not so fond of. I'm hit or miss with the new C. I'll always love the classics and still admire the W220 and W211 gen, etc.

FFS! There are so many versions of the 7G-Tronic that improved overtime.
The software in my MY14 version is much smarter than my "old" MY12 E-class.
Now I have to agree that 7G-Tronic is nowhere near as good as the ZF's 8 speed automagic box.
Let's not bash the 7G-Tronic like it's a POS.
