Posted on 28/09/2019 22:42 by EmilysDadDoes it use the same algorithm to start the engine sooner cos there's a big wagon coming and you need to move NOW and not in a second after it's started the engine? 🤔

No.
The ability to get out of the way of a big wagon is called driver anticipation and ensuring that the driver is aware of what is going on around him/her at all times!
Some information about the Mazda i-stop system (I used to have a CX5):
i-stop and Clean Diesel Engines
Unlike gasoline engines, which use a spark plug to ignite the air-fuel mixture, diesel engines compress the mixture until it spontaneously combusts. Therefore, to restart a diesel engine, sufficient compression is required.
While conventional diesel engine idling stop systems require two engine cycles to restart, Mazda's unique i-stop needs just one cycle, thanks to its precise control of the piston positions. As a result, i-stop achieves the world's fastest diesel engine restart time of approximately 0.40 seconds (internal measurement on vehicles with automatic transmission) and its operation is barely noticeable.
i-stop offers a quick engine restart and a natural operation with little vibration and noise.

It seems to me that most of you seem to be missing the point about stop/start systems. It’s not to save you fuel it is to reduce emissions in queuing traffic. Shouldn’t we all be trying to do our bit in such circumstances and with all the information we receive these days about global warming but particularly health problems for those living near to congested roads?
I refer back to the original question for this post and that would be to follow the advice, if it’s included, in the vehicle handbook/manual.

Posted on 21/10/2019 02:32 by DS3Stop start saves a massive amount of fuel if you are driving in town. Not using it is, for want of a better word, stupid.
As for towing with it, my Volvo V70 turns the function off as soon as a trailer is attached.

Regarding the OPs question, some BMWs suffer from cooling problems when towing, maybe it would pay to disable it when hitched.
My car (not a BMW) automatically disables stop/start when a trailer hitch is sensed, and as I dislike it in normal driving and it defaults to 'on' I always disable it when I remember.
Not sure it is good for the caravans fridge and leisure battery to have it intermittently cycling on/off, so happy the car has decided to disable it.

Fuel economy goes out of the window when you attach a big white wobbly box to the back of your car .... and in my case if I'd wanted fuel economy I wouldn't have bought a 3.0 permanent 4x4 with the aerodynamics of a house brick.
I don't think I've tried towing with stop/start enabled
