ECO is absolutely 100% USELESS on the 2014 E350
I agree with michael61 who stated that this system works well in this car. Compared to the S/S system in the BMW 3 Series, the MB system is seamless. When engaged, it seems to anticipate your car's next move: as brake pressure is released, the engine re-starts without any drama.
For heavy traffic situations where there could be long stops, this system, if engaged, will reduce fuel consumption and help to reduce air pollution.
The BMW system was intrusive and annoying.
About the E250 vs Prius I read an article a few months ago which proclaimed the E250 as the most fuel efficient car in America beating the Prius after an extensive test drive.

The article to which you refer was in the February, 2014 issue of Road & Track, by Jason Cammisa, Senior Editor:
"The most fuel efficient vehicle in America is a Luxury Car: the Prius Uncrowned". The E250BT rules !

Go drive an Infiniti Q50 and tell me that statement with a straight face. I just put 600+ miles on one last week and couldn't wait to return it as there were so many design/quality flaws.
Just some of the problems I encountered in one week with the Q50:
1) wipers + washers which couldn't clean the windscreen
2) Putting a touchscreen down by the driver's knee
3) Putting tiny little 'buttons' on said touchscreen
4) Putting a second screen up closer to eye level which doesn't do much of anything
5) Putting in computers which flat-out don't work and crashed constantly during the week I had it.
6) Reverse camera guide-lines won't show up until the car has been powered up for 2+ minutes. I guess you're supposed to turn on the car and listen to the radio for 2 minutes before reversing each time BUT....
7) The radio & AC controls also don't work until the computer has booted up....BUT
8) Air con controls didn't work at the dealership because the computer crashed and had to be reset. Similarly, I was told that it was "normal" for the AC controls to be lagged up to 30 seconds.
I'm with Phil -- the BMW start/stop, in particular its roughness and eagerness to engage, bothered me when I had one for a week. The first time it engaged I thought someone had rear-ended me.
If you want a car which shuts the engine off all the time, there's the E400, which benefits from a larger storage battery + electric AC. The latter should make a big difference. On the E350s I've played with, I noticed the ECO icon was green far more often when it was overcast or at night. I'm in Florida and it is summer, YMMV.
I do wish you could permanently enable/disable the feature though. From my limited (week-long) experience, I'd probably leave it enabled. I like the silence and lack of vibration at some of Florida's 5-minute-long red lights. Ironically, the Lexus RX hybrid I had for a few days couldn't make it though an entire red light without firing the engine back up and sometimes it didn't even bother to shut the engine down -- and that's a true hybrid complete with a golf cart (EV) mode.
The initial release Q50's did have issues with their tech. Since then I believe they have had software revisions which corrected operating flaws. I did not hold on to the Q50 very long, I loved its interior and tech and the back up camera was much better then my 2011 e350 and was the interior. There was a few things I disliked and infiniti still has some work to do before they can be mentioned with the Audi, Mercedes, BMW, Lexus level brands. I put them with Acura.
My E350 MY2011 P2, was a car I only kept for 3 months, I turn over daily drivers annually but I could not get myself to keep this car, also quick sale made it easy to let go.
I took delivery and unfortunately was dissatisfied from day one. I loved the exterior styling but could not get over the lack of tech and "basic" interior. Also MY2011/2010 had the 268hp V6 which just felt under powered to me.

Currently have 535i M sport MY2013. IMO the interior, tech and driving dynamics are far ahead of the current model E Calss.
With the new C Class, I like where Mercedes is going, they did a much needed tech overhaul, looking forward to the next generation E.
As far as the feature OP is speaking of, I find it annoying on my BMW as well, I always disable it, it stops the car at stop lights or in traffic when completely stopped to increase fuel economy. With the amount and type of driving I do ( mainly freeway ) I don't see any value.

The Best of Mercedes & AMG
Loving the CLS so far, but the technology is behind the Q for sure.
Not true at all. The entire buyback process took about four weeks from the time they decided to buy the car, until day of surrender. They gave me a check right there in the spot.
Infiniti handled the situation like a champ. Won't hesitate to buy another vehicle from them, as a matter of fact I still own one that was purchased the same day along the one that got bought back.
The Q
-excellent cross traffic intervention system
- adaptive steering, meaning the car could drive itself including slight bends on the road for miles at a time (freakish to see the steering wheel turn)
- key fob recognition and linking by driver would set the entire car to the specific user driving configurations ( ac, radio presets, automatic steering and seating configuration)
- more user friendly nav system
- adjustable steering feedback
- easy access to apps ( although most have not been released). No digging through the command menu
- around view cameras that turn on automatically once objects are detected
Those are just some right of the top of my head
I do love the CLS that much more
In my case they admitted the car was a lemon, but right before the lemon process they bought it back.
It worked great in my SL550 but it hardly ever turned green. When it did
the engine would start before I got my foot off the brake. You couldn't hardly hear the starter.BUT IT NEVER WENT GREEN. Of course I'm referring to the system, ready to work. It would work about once a mo
nth. It might work for a few seconds at a red light then it fire up as the icon turns yellow for no reason. It drove me nuts.... I wanted it to work.

Find it hard to believe that quote is from MBUSA, especially with the Republican reference. If God Blesses America, what does he do to Germany?
