General Usefulness Of Start/Stop

[GettinBetter]

PROS:
1. Checks the status of the battery and earth system.
2. Checks the status of the microswitches that determine whether it should work or not.

CONS:
1. Stops engine for periods too short for good fuel efficiency/wear & tear.
2. Stops engine even after a spritely burst of the turbo.

Call me old fashioned but I hate start stop systems & won't buy a car which has it, it also wears batteries & starter motors out quicker.

Usefulness? Negligible at best. Just allows FIAT to make dubious claims about fuel consumption, efficiency and emissions.

Yes, same as the hybrid,

FYI The 1.0 mild hybrid engine uses the alternator to start the engine during stop/start operation. Also adding in a bit of power from the hybrid battery when accelerating. Starter motor for initial engine start only.

Can't be good especially for the turbo if it has one and the starter.

I think the 1.0 hybrid is 3 cylinder naturally aspirated engine. I drove one as a rental and the regenerative charging when you take your foot off the gas takes a bit of getting used to compared to a conventional engine.

We should all be grateful fiat didnt manage to turn it in to a stop/stop system despite there best efforts .

Mine is permanently switch off. It's just annoying and serves no purpose.

The Younger Mrs S' Rasputin has a non-S/S battery which has *just* insufficient charge that the S/S never cuts the engine, but does start it when I stall it.

Every summer, or after veeery long runs, the battery does have enough juice for the car to stop the engine.. but usually it's only for just a few seconds before the car changes its mind again, which does get annoying.

On the other hand, one long hot summer the battery obviously hit a purple patch and the S/S started working perfectly.. that is, it turned off and never restarted the engine until I pressed the clutch in. I was impressed.

I bought and fitted a little pcb on my last start/stop as soon I bought the car (new)

Left disabled for the next ten years , it just wears out stuff.

Prior to fitting the PCB it's annoying that it opts you in every day.... the pcb just waited a second on power up and then emulated you pressing the button (to turn off)

I was so glad this 595 doesn't have it.

They are the biggest cause of traffic hold ups. I love the way I'm half way to the next lights by the time the stop/start next to me has even moved, but hate when I'm behind one and you wait and wait and then finally they pull off. I doubt it has any fuel saving credentials at all.
Then there's lane assist another pointless addition to a car on a normal road, my daughter hired a almost new golf the other week. Didn't know it had lane assist.
Whilst trying to overtake a cyclist it nearly diverted here into it, frightened the life out of her. I had to work out how to turn it off so she could do it before every trip, pointless.

Mine ran for three years (2014-2017) with a non-SS battery and the SS performed to spec. Then I got the EFB which is still in the car now but at the same time turned SS off. Fortunately my car has the more sensible arrangement in that when you switch off SS it stays off.
