Thanks Brandon

Okay, all you smarty pants people ... I thought you would have the answer for me. ;) I'm counting on all y'all.
Well, it stands to reason that it would increase wear and tear on certain items, especially the starter. Possibly the engine itself. How much does the auto stop/start actually save? My personal thoughts are, not much, but someone must think it does or they wouldn't be putting this on so many vehicles. I guess time will tell.

Supposedly, the eTorque system on my truck increases city mileage by about 2 mpg due to the electric assist on accelaration, and that's separate of the automatic stop/start. But again, time will tell whether or not it's worth it.

I was wondering if they get points towards the Economy (CAFE) standards? Even if it is not used...

My guess is yes, and that's probably a big deal, especially with American manufacturers who are surviving on trucks, SUVs, and sporty cars. Take Chrysler (Stellantis) for example; they don't sell many cars that aren't Chargers and Challengers. Aside from those, their business is Trucks and Jeeps.

I think this is the main reason. If it gives better milage on the official government tests, they won't care if it helps in the real world or not. The govt has allowed the temporary shut off buttons, but from what I understand the govt will not allow a permanent bypass of the shutdown system and still allow the manufacturers to use it during milage tests.
 
I typed a big message for GD yesterday and now I can't find it,, but basically I think they use the boost motor to restart the engine, so try this sometime -- turn your ignition 'ON' but do start it. Put your foot on the brake and drop it in drive, now take your foot off the brake and see if it starts. This might come in handy if the engine start battery goes dead,,, maybe from leaving the radio on with a bunch of speakers. Let me know if my theory is correct, thanks.

I haven't dug deep int it yet, but my understanding from reading is that it uses a traditional starter motor (sounds like it too). What it apparently does not have is a traditional alternator. The 40 volt motor/generator apparently uses a voltage converter to charge the 12 volt battery.

It does have the auto start/stop function, same as most new cars. But unlike the rest, the eTorque system supposedly continues to drive the A/C compressor at stop lights when the engine shuts off. And it provides a low speed 130 ft lb torque boost for pulling. What I wonder is, how it drives the A/C? Since it has cylinder deactification, I wonder if it closes all the valves and continues to spin the engine while stopped? If so, that would explain the near-instant restart; all it would have to so is to re-activate the cylinders and the engine is running. That would explain your theory.

While I have wrung it out yet, the truck is VERY lively off the line. As powerful as my Tundra is, the RAM feels far stronger still.

Our old Vue Hybrid would shut off, (VERY discerning at first), but would just be running when you took your foot off the brake with no starter engagement. After getting rid of it I wondered if it would start itself with a dead battery, I wish I'd tried it. What happens to your truck if you're in limp mode with a bad battery?

Blue pills, I suppose.

You old guys can advise me on that. :)
 
To answer...no cars will start themselves with a dead battery.

But since the eTorque uses the 40 volt system to produce 12 volts, maybe it has a backup. I believe the 48 volt batter is warranted for 100,000 miles.
 
Currently most used ones which are 3 years or newer are actually selling for MORE than their original price. I'm also hearing the quality of the new models are substantially lower for several reasons, one being the shortage of skilled workers.

Saw this 2018 toy hauler one on Facebook in Tallahassee for $35,000.
