Didn't it have a engine cut out at 60km/h as opposed to 40km/h here. Anyone know if this is true.

our work van has this feature. it stops when you want to go, then you have a 1-2 second delay while it restarts, then it bogs down because the vehicle is already moving and trying to accelerate.
when i stop at the boom gate at our building, it stops just as i finish the swipe and want to start moving again. it looses power steering when the stop/start kicks in. it looses power to the gps tracker, making it beep for a fresh logon (key-fob).

Even on this car, it would restart as soon as I took my foot off the brake.

I reckon hybrids are the way to go for heavy city traffic. I'd buy one if I had to drive in heavy traffic regularly. |

Stop/start system in hybrids are way different than OP's car...
Hybrids use a giant battery and generator to start the car instead of the flimsy weak starter motor. You are saving fuel but I think in the long run, engine, the 12V battery and the starter will wear out faster. |

Stop start in a car thats not a hybrid, i find it a tad bit scary. My mums car has it, and ive only been a passenger in that thing. But blanket statement, people in sydney drive like theyre constantly running late, especially in the area my mum lives. 50 means 70. So the minor delay pulling across and into traffic in a slow to begin with benz is sketchy. My old boss turned it off in his old turbo v8 x6 because he is constantly late and drives like an oportunistic f wit. His x6 spent most of its life back at the dealer and the 528 loaner he usually had you couldnt turn it off and yeah, picking the gap was sketchy. Not so point and shoot. His q7 then sq5 both have it disabled.
Heavy traffic, yeah, i can see the advantages. Especially if you dont plan to keep the thing forever so any potential maintenance in the future is not applicable. But, for picking the gap? Its a yeah nah for me. |

Do they do stop start in anything manual? I know manuals are becoming more and more scarce, but if they do, how does that work? Minor delay, give it a couple of rpm then ease out of the clutch? Now im curious. I might have to take my grandpas prius out for a spin and leave it on petrol/electric. I suspect they do not have a conventional starter motor being a hybrid and use the electric motor to sort of almost clutch start the petrol generator. Grandpa sort of explained it to the best of his knowledge, he is really old. He says theyre all electric untill either the batteries need a charge or flooring it/going up a hill/ anytime it needs all the power, thats when the engine kicks in. I know my brother hates the prius because its way too small and he isnt a button pusher, so leaves it in eco mode. But id be interested to push buttons and compare it sort of evenly to the yaris i used to get as a courtesy car whenever my work cars were at the mechanics. Yeah it was too small and slow, but i loved driving that, what it lacked in size and speed, it made up in turning circle and fitted in the tightest of spaces. |

We had a 2014 Mazda3 SP25 GT with a manual gearbox.
Pretty sure you had to put it in neutral, take your foot off the clutch and come to a complete stop for the stop/start to activate. So in the 3 years we had it I reckon it kicked in no more than a dozen times. Living in a rural area probably helps, no real peak hour traffic to sit in for long periods to warrant taking your foot off the clutch at traffic lights.

.:4:. when you do take to GP's Prius out can you confirm that the ICE cuts out at 40-50km/h Just curious.

Have a 2019 mazda 3 GT and cant stand it. First button I press is to deactiavte it. Wish you could turn it off permanently.
dont get me started on the adaptive cruise control... That function is a death trap and again, has to be turned off each time the car is started.

Stop / start does not use the starter motor. It senses what stage of the cycle the engine is in prior to shutdown and sparks the cylinder that has just had fuel injected into it to get it going again.

Those that do have a starter with stronger internals than normal cars as well as an uprated battery.

Yes, price of a new battery sucks. We’ve been through three in the last five years roughly. Stock replacement is almost $500 but most battery retailers have a very similar spec battery for about half that. Funnily enough it gives us warnings that the battery is dying, first the windows auto up and down stop functioning, then about a month later the stop start stops working. After that it could be days or weeks before the battery fails completely. Haven’t had to do a starter yet and the car is at 112000km. |

3 batteries in 5 years is a very short life expectancy.
Is that a common trait to your model I wonder? Any savings in fuel are lost on replacement batteries!

So it does not use starter motor at all after a cold start?

It could be an effect of not using the factory specced battery, but I have seen on American crosstrek (same as the xv) pages that they do have a healthy appetite for batteries. But the stop start isn’t really there for fuel economy although that’s what the marketing blurb will say, it’s about dropping emissions. You can have the centre display set to show you have much fuel it saves you on a trip and it’s never a great deal. I tend to drive so it doesn’t activate, I’m not a huge fan of it. Other than the weak cvt I love the car. It’s slow as hell but still fun to drive in a weird way. Sent from my iPhone using Tapatalk |

Err no, they definitely use the starter, that's why they require special batteries

Mazda is unique in that it doesn’t rely entirely on the starter motor. I believe most other manufacturers use heavy duty, faster starter motors.

My 2009 Smart Fortwo MHD has a starter generator, it looks like a alternator and spins the drive belt to start the car, the car does not even have a starter motor
![]() Its quite a odd feeling when the start stop is working, you can feel the motor turn over silent with no stater noise, then it fires up When I had it on the hoist the last time I had a good look around and it actually has a place for the starter to go cast into the engine and its machined to accept a starter, but it just has a thin tin block off plate covering the opening. I think all the different manufacturers have their own way of starting with the start stop set up, be it starter motor, generator, fuel and spark or a combination of two for the most efficient and quick start it requires. I have the small circuit board fitted now so it does not come on unless I press the button for it to be on, the way it should come from the factory I think. |

Special (uprated?) batteries could also be for the electronics that need to keep going when the car is off. Sent from my SM-G973F using Tapatalk

Why do we even need starter motors then?
It should sense what stage of the cycle the engine is in last night you shut the engine off & start without starter motor in the morning.. They use starter motor to start again. It can be more beefy starter compared to your usual car that doesn't have an auto start/stop system. |

fuel is injected into the cylinder and the start motor applies a small amount of torque to the crankshaft, all of which makes for a more refined and quicker start They use starter motor to apply "small" amount of torque. People tend to skip detail and most believe that Mazda does not use starter motor to restart. |

Try disconnecting starter motor and see if the car will restart without it .
