BMW is not the "only" company doing start/stop. As someone said, Porsche is doing it as well in their Panamera and Cayenne's. Its annoying and I agree, has to put undo stress on the engine. I always thought starting and stopping used more gas than just letting it idle but maybe that has changed. Also, these companies are doing these things because governments are forcing them to adhere to higher and higher mileage standards...so it is in fact politics that is leading to overzeolous idiots at the EPA and beyond trying to mandate ridiculous rules with the hopes of appeasing the environmentally emotional crowds.

Unlikely. How can the mfr claim the benefits for regulatory purposes when drivers can so easily opt out? Same goes for permanent selection of Sport mode.

people who buy bmw's don't really care to save few bucks on fuel, if I wanted fuel economy I would buy honda civic, this 4 cylinders and auto stop is ridiculous... and to have that option start by default is even more retarded...

What a bad brand move it would be if that was the attitude of companies like BMW and other luxury car makers. It's like intel saying; if you really want that fast processor then we'll just ignore the power consumption it takes; versus innovating and getting both right. |

When I had my 2011 535 (exactly same engine and same car as my 2012) I was getting 21.5 MPG on my daily commute. After getting the 2012 and leaving the Auto Start/Stop function enabled (default) I'm now getting 24.7 MPG constantly. Same commute, same traffic. If anything, I should be getting worst mileage on the new car being it is barely broken-in. Instead, I'm getting more than 3 MPG. 3 MPG may not sound like much, but if you consider that I use an average of 20 gallons per week (refill every 6 days), I'm getting about 60 miles per week more. Multiply the 60 miles extra per week x 52 weeks / year and you get 3,120 extra miles per year. That is more than 6 weeks of free gas every year, or around $510 per year in gas. Given that there is NO maintenance or warranty costs for 4 years, I will save over $2,000 in those 4 years, and I don't care if the car needs a new starter, as it will be covered by warranty. Also, most likely I will trade it in at the end of the 4 years. So, bottom line, I like it, it saves money and it is good for the environment. BTW, it should be fairly easy to change the switch from a NO (Normally Open) circuit to an NC (Normally Closed) type with a very simple in-line circuit. How much would YOU be willing to pay for this circuit?

I see your point if you lease it, but many people buy it out after lease, or buy used one.... replacing turbos or a starter can end up costing way more

The big point off auto start/stop is not to save some money for one person, it is for the environment, One car won’t make any big difference but if every new car had this it will make some serious difference.
Just look at Alex_C post if you multiply his number on all the new cars sold in the US it will be quite big numbers. I didn’t find any updated information but there were around 10 million new cars sold in 2009 in the United States. And then we have the rest of the world I do not point to any morals to users in this thread that will turn off this function just making a point why you will see this in many cars in the future I bought myself a 530i 2012 witch do not have this options |

Right, now factor in that engines in the second hand markets will last half as long, plus all the energy and and environmental impact of having to build more engines completely offsets this moronic concept of killing your motor and restarting it.
Plus, emissions are more volatile during the first two minutes after engine start. Did anybody consider that? I agree that stopping an engine at each extended traffic light will give better gas milage. But, the current motor design is not good enough to support such stresses long term. Especially when you now change the oil once a year. Time and statistics will tell us who is correct, right? Quote:

Not to mention that in (supposedly) "freedom" - oriented countries/societies, the government is supposed to actually give people a choice and not try to constantly "force" all of the decisions upon them (like a personal choice of NOT driving (or paying for) a car with a bunch of forced ecology - oriented "band-aid" solutions) |

I have a new us spec 2011 BMW M3 that has auto/stop feature and it is set to default off whenever I start the car. I never actually used the feature, but I am glad its off by default as I am never going to use it.
You might be able to code it to be off with a bmw scan tool.
