No offense but if you somehow think that the half second of hesitation from the start stop feature is going to cause you to wreck you haven't driven enough crappy cars in your life. If you need to worry about that you shouldn't be making a left turn.


Personally I like the feature I think it works great, but there is a reason for the button, and in stop and go traffic unless you know you're gonna be stopped for a bit it needs to be turned off. Otherwise, daily, its barely noticeable.

 

for me i dont think it made too much of a difference, fuel wise i'd have to fill up 1x/week even with ECO start/stop, for me the one thing that i hated was the constant jerking motion when it would turn on/off in traffic

 

Agree with you totally. I haven't been in a car that has the stop start better implemented than the E class. For me it is very seamless and intuitive. The hesitation being talked about happens only in one situation (when the brake hold and eco stop are both activated). In a regular braking (without the hold), it's not an issue because by the time your foot has released the brake and moved to the accelerator, the engine has already started. That extra half a second is not available when you have brake hold activated (since the engine start process starts when you have touched the accelerator in this case, as opposed to releasing the brake in the earlier scenario). I hope I am making sense.

 

No gas saving, more things to go wrong,more $$$ to be made on us just regular people.
Me personally would never get one with that future,especially when you have to shut it off every time you start the car. Government just stuff our faces with stuff we dont ask for.
Can you imagine when you sit in traffic for about an hour, stop/go, ur car starts 100 times, thats just stupid. i wonder what is next?!

 

Totally wrong. I have never used both brake hold along with eco. The eco by itself causes the hesitation. It has nothing to do with double pressing on brake to make it hold. Who in there right mind would double press the brake while waiting to make a left turn? I must have an awful quick foot to make it hesitate according to what you say because every time the eco is engaged it hesitates. I am an old guy and I know I am not that quick.

 

I did some testing on the stop and go system, it increase the gas mileage by about 0.5 to 1 MPG. I agree with pamiboy, Mercedes' start and stop system is one of the best, the BMW and Lexus system are even more intrusive. Mercedes' system is so fast that by the time your foot switch from the brake pedal to the gas pedal, the engine is already started. One of the reason is that the Mercedes start stop system does not use the starter motor. The engine starts by firing the cylinder that is was closet to firing before it stopped. Like I said earlier, it take a while to get use to. On stop and go traffic, I just turn it off.

 

FWIW, not to say that no one else has legit issues, but my car's start/stop does not have any detectable hesitation.

That said, I spent a week in a W205 C300 and the start/stop system was awful. My W204 will not shut off until I am at a complete stop, and only if I am firmly pressing the brake pedal. It will not start until I fully release the brakes. The W205's system would sometimes cut off as the car rolled to a stop, sometimes it would start up while I was still lightly pressing the brakes and lurch forward. That is one of many reasons the W205 is scratched off my list of possible W204 replacement down the line. I am afraid the W213 is probably just as poorly executed.

 

The car won't stop/start 100 times in a row. I read somewhere that the maximum amount is 4 in a row (in short succession).

 

In BMW, the engine starts as soon as you take your foot off from the brake pedal.

 

Same with my Mercedes, but the Mercedes starts much quicker. One thing I did notice is that the 4 cylinder engines start up is more intrusive than my V6 and V8.

 

I have no complaints about the eco start stop on my Mercedes. Works better than the ones on the last two BMWs I drove.

 

Try sitting in the southern USA, with 46 Celsius temp, sweating at every intersection, because some MB execs don' get it that I pay 0.61 euro per liter and would rather pay, than having to turn off eco crap 700-1,200 times each year.. we should be allowed to control the settings in our car, and turn off unwanted features permanently....

 

I think it's done on purpose to meet government CAFE numbers. You can thank your government for that. They gotta squeeze every gallon.

 

To all those who has complaints about the start stop system, next time you wake up in the morning, count how many buttons you will push that day. My guess is that it is close to a few hundred buttons, heck, I just pass a hundred buttons right now typing this post. So what is one more push of the eco button in our perpetual button pushing world?

 

+1. Exactly.

 

I live in Texas. Roast my **** off in the summer. I still have no issues with the function. Car stays plenty cool. I have also personalized my settings so that if I do not want it go off if doesn't. I just change to my individualized program after I start the car and no I have the steering, comfort, engine dynamics I want.

 

Nope.. you still have to turn off the eco-crap every time, to make it work. That is twice a day, or 4 times every day to get rid off some Euro crap that you never wanted. For the love of God, let me turn off , one, and for all. The s**t that I don't want. I don't live in Europe and can afford the gasoline, so no more ecu, blue*sh**t. Give me a great MB without eco crap.. please!!!

 

Sorry, got carried away.. but after 30+ years, as a loyal MB customer , I feel that they are getting rid of me, with tiny 4-cyl engines and eco, European crap.. I used to love MB and bought one for each of my 3 sons, but now I am just disgusted.. it is time to understanding that US customers are not the same as European buyers.. so, if you want to be Fiat in the 1980s, go forward,and loose all customers, but if you want me, as a buyer (bought at least 25-30 MBs in the last 30 years), please, please STOP."....

 

Yeah, eco is not European crap. It's CAFE. Which is US. They're supposed to hit 60 by 2025 for passenger cars which works out to an EPA window sticker of 43. For 2017, it was 33. 2016 it was 31, 2015 was 29, and 2014 was 28. Notice the trend? That's why you have a 4 cylinder turbo...

Thanks.. that is actually helpful.. appreciate it!!!!

 

Thank God we still have people like you on this planet, because looks like most people actually go for that eco garbage. The sad thing is, we, paying for something we don't even ask for. Its not like you buy a car and you get the eco free. Its like you buy a car then you pay for eco then you like wtf i need this crap?! Oh but wait.... i got no choice ha haaa haaa

BTW anyone i know, dont matter what car they own with eco they just hate it, i mean hate it!!

 

^3 posts up. FWIW the new S class supposedly will have a inline 6, and I'm sure ECO. It is not going to disappear. Just like runflat tires, and no spare tire to save weight, and FUEL! I owned a 2014 E350, and when it engaged it would restart to keep the AC on after I had driven a few miles, and it wouldn't turn off the engine until I had driven a few more miles.

 

The gas might be cheap in the US, but we paid a much higher price, not in dollars but in the wars we fought in the middle east to stabilize the global gas prices.

 

1. I feel the Eco's hesitation, and yes, that annoyance prompts me to hit the button at every startup.


2. I am, likewise, frustrated not only at all this manufacturing "faux-green" think-speak that not only forces consumers to accept the claptrap, it engenders a faux-caring mindset that you're actually accomplishing something good in the world.


3. I am frustrated that not more people are frustrated by this pervading "Eco" mindset that is so far removed from logic as it is entrenched in political feel-goods, and has now become the new "cost of doing business." And people buy it.


4. The Eco start/stop function, in itself, is but one of a myriad of brain-dead "solutions" which, in effect, offer little tangible benefit. But they sure do make folks feel like they're saving the planet as they save money. And yet, neither pans out.


5. The only thing worse than this asinine Eco start/stop feature is that folks actually like that it is shoved in their face as a default; or simply accept it in complacency.


There, I said it.

I'm not sure why you said it. The whole reason was stated above, government CAFE requirements. At point they let it slide and cars got better so they were able to achieve the numbers by cramming more technology into the engines, but at a certain point, they ran out of ideas to squeeze more mileage out of a gallon of gas and the government jacked up the number when gas hit $4 a gallon. They have to meet those numbers or they end up paying a big fine and it's not good to have a rep as a gas guzzler so they also have to be competitive with other auto makers.
