At least you can turn off the start/stop feature. Turing off the A/C every time you get into the car must take a toll (however small). That can't be changed so we're stuck with it.

About 1.5MPG average. I've mostly been eyeing the fuel gauge which seems to be decreasing at a slower rate....
Again. The savings aren't tremendous, but the system is FAR less intrusive and much more refined than any start/stop that I've used. Mainly from the DCT trans as opposed to a car equipped with an automatic + torque converter. I suggest you guys at least give it a shot for a full tank of gas and judge for yourselves. |

used it for 3 years on last m3. use it all the time on the m4. came in handy in jacksonville, daytona, and miami this weekend. i use it because its time its not spitting out emissions for no good reason. and it saves some fuel. nothing wrong with that.
the additional wear on the engine would likely be not even measurable. The system doesn't work when the engine is cold. once its warmed up everything is all lubed well. the starter is heavy duty designed for repeated duty. just about everyone in europe uses it and i haven't seen a massive recall on starters or engines blowing up left and right over the past 5 years so i'm guessing its okay to use. and you can be an enthusiast and use it. and you can have a sports car and still care about emissions. someone tell me i'm not using my own car the right way and should get something more appropriate gets absolutely zero F's from me.

Hi. My dad used to work for a major electrical motor manufacturer. Big ones. Power generators etc. He looked after beating tolerances etc.
After that he worked for lotus. First time I took him for a drive in my e92 and it stopped at the lights he couldn't believe it. We had the same discussion about hot oil, oil in the head, and coating the crank, etc. His point was that was guff! When running the bearings float on a film of oil constantly drawn through the bearing as it rotates and when stopped the bearing then squeezes out that film... Something about 99 % of bearing wear is during stopping and stating and doesn't matter whether it is hot or cold...previously running or not. I wonder if the e9x bearing issues are due to the now famous stop and start and now whether f8x is next in the line for bearing issues. It would be interesting to know if those who had e9x bearing issues tended to live in cities or have commute with stop start traffic along the way. Last edited by crypticc; 02-17-2015 at 03:44 PM.. |

I actually like this silly little feature. Passengers are convinced the car has stalled. That's fun.

I'll definitely will be trying out the differences, but it will be really hard to keep the foot out of it for a real reading.

Unfortunately, my car is still waiting for a boat. It's almost been a month.
Plus, it will be sitting in my garage till June. I'll surely calculate it then.

I had to replace the starter on my 90k mile E90. how long do you think starter will last if it's used 10-20 times a day?
stop/start disabled in both my M3 and wife's car.

Given that global warming/climate change is a scam - I don't understand any of this emissions nonsense. Further I couldn't give a crap about the size of my "footprint".
The first thing I did was code of the ASS. Felt good. |

Does anyone really need any legitimate reason to do anything to their car? we could argue legitimacy for any modification done; at the end of the day it's your car do with it as you please. |
