auto stop/start

So it seems that this feature will be standard across all 3er. Does anybody know if this will only be for over seas models or does this also include US models? Personally, I don't care for this feature. If this does become standard for the US, does anybody know if there will be a way to disable this feature?

I'm pretty sure its standard and cannot be deleted. Its on everything now. A friend just got a new CLS 6.3 and its got it! I think Porsche has it across the board too.

From some pics there seems to be a button right above the start button with an 'A' with a circle around it and labeled 'off'.

I think this disables the auto stop/start. Probably press to turn off and once car is restarted, it is turned back on again.

That would be good . Ultimately I bet we will all have to get used to that on/off stuff. I bet its weird.

Start/Stop is standard across the F30 including us here in the US. You can defeat it (the labeled button mentioned above). It defaults to 'active' every time you start the car from other posts I've read (). I suppose we'll get used to it.

No different than DTC now. I turn the older traction control, ASC, off in my M Coupe every time I get in. It's second nature now. If Auto Start/Stop bothers you, it's not hard to disable. You'll already be hitting the Start button every time, so just jabbing the button above it shouldn't put you out too much.

I've driven an X3 with it. It doesn't seem that intrusive. I can see why some people might not like it but you hardly notice it. It's a good thing you can turn the feature off though, imagine if you'd ran the battery down and had to jump start the car. You get to the first set of red traffic lights and d'oh!

found this on the motor trend review
"or to take the automatic out of sport shift mode, which disables the new auto start-stop system."

If you are driving a manual transmission, it'll only cut the engine if you put the car into neutral and release the clutch pedal. If you leave the clutch pedal depressed or a gear selected it will not cut the engine. If you are driving an automatic car (as I expect many people in the US market will chose to), it may possibly cut the engine any time the vehicle comes to a complete stop and the only way to prevent this is to press the button above the Start/Stop Engine button to deactivate the Auto Start/Stop.

You won't get caught out with a flat battery either. If your battery is too low, or you are running too heavy a load electrically, the car won't stop anyway. It also won't stop if the temperature is below 3c either (38 F).

I only switch mine off if I'm in a long tail-back where you would be start/stopping every few yards - can't be good for the starter motor. Otherwise it's pretty seamless and apparently is responsible for 8% fuel efficiency improvement.

That's a good point. It was just something I thought about after I helped out a colleague jump start her car; that it would be annoying if she got to a junction and the auto start/stop cut the engine before there was enough charge in the battery to restart the battery. Good job they've though of such a scenario. Her can in any case did not feature auto start/stop so it a non-issue in actual fact. Her only real issue would have been if she inadvertently stalled the car at a junction or something!

Starter?

Not to sure they would bother using the starter (and battery) to re-start.

I thought they would re-start the engine like Ford does. The computer calculates the position of all the pistons and vales and then squirts a little fuel in the most appropriate cylinder, then lights off the spark plug and the engine is restarted!!

Just drive in sport or manual mode and you'll be fine, the dreaded start/ stop will not function. I was worried too but once I read that I was excited that BMW didn't f$ck it up again. And with the adjustable damping feature, aftermarket suspension may only be for those wanting to slam. From what I've read in other models sport is quite stiff.

With the F25 X3 I occasionally drive, I'm pretty sure it restarts the engine using the starter motor after an auto start/stop. It is a diesel though. So maybe diesels with auto start/stop have to operate in this way because of the lack of spark plugs whereas the petrol [gasoline] engines can operate in the same way Ford uses.

On a side note wouldn't the spark plug still require the battery via the coil pack to generate the spark? Or am I being stupid here?
