Auto stop start on a 2025 GT premium.

[Gregs24]

I assume Ford uses an auxiliary battery for the ESS function like Dodge does? That's what annoys me; the added complexity to the 12V/charging system. You even have to disconnect the batteries in a certain way if you want to totally kill 12V power for safety before working on it.

Having said that, I've got a Jeep with the ESS feature and 200,000 miles with no failures of the starter or flywheel. And through testing and hand calculation I found that ESS saves about 10% fuel on the Jeep. Not sure but I'm guessing it would be less of a difference on a car like a Mustang.

No, just the one battery (and most European S/S systems just have one higher spec battery), so no need to be annoyed about something that doesn't exist . The more modern systems use an integrated starter generator (ISG) which actually simplifies things more than having an alternator / starter etc

Savings on a V8 will be more than a V6 or i4 as obviously more cylinders use more fuel when idling. Not sure what the Jeep has in your case. It is around 0.5 to 1 litre per cylinder per hour depending on the engine. The more time idling the more saved, so stop start traffic gives the best savings.

Savings are relative to use. You may be ‘idle’ (as in not moving) but you will more than likely be simultaneously generating electricity as well as heat (btus). Lets see an ev do that while idling.

You do. Unless you roll it in track mode, maybe sport too I’m not certain.

Track & Sport modes turn it off.

I just realized you can set the A.S.S. to off in your profile settings! Since I already always switch to Custom Profile every time I start the car, it eliminates the additional pressing of the A.S.S. button! Thank you Ford!

Only if you have that option - memory seats etc

I went through the vehicle menu and found the auto stop start on off, I set it for off and it worked fine. Then the next day backing the car out. I went into the garage and it stopped. reset it worked fine for a while and then again it auto stopped for me. Any help would be appreciated.

I have a ‘24 GT manual that has auto start stop. What I’ve been doing is just pressing the red start button and at the same time press the A.S.S. switch when you start the car. The light comes on turning off the switch….check it out. Ends up being one press, two fingers each time I start the car.

Stupid comment!

Porsche 911 has stop start and that isn't a Prius either!

Ironically the Prius does NOT have stop start as it is a hybrid

I am glad my Mustang has stop start and that I am not burning money when not moving.

Face it, you just like the fact that it makes your Stang sound like an EV (i.e. silent at the stop sign, etc.) and not the idle of a rumbling V8...comical.

I assume that comment was made in jest but if one reads all the relevant messages in this thread and thinks about it a bit, well maybe…

Sensibilities are often age and regionally influenced. Just a part of human nature.

I don't need a rumbling V8 at idle to maintain my manhood The comical aspect is for those that do!

Silence when stopped - great

Anyone who says they drive an 8 cylinder sports car but need AS/S to help 'save gas' chose the wrong car and the wrong career path.

Well nothing to do with my career!

Just remember the Mustang uses a LOT less fuel than many SUV's and trucks so is already actually better! Saving a bit more with stop start is a bonus. I'm not so insecure I need to sit listening to a V8 burning fuel for no reason.
