eTorque?

I agree about redactions. And I liked the That 70's video.

But the full article doesn't change the gist ("truth"). If the extra wear problem had been solved, the (20 month old) article wouldn't refer to potential technology to mitigate it. Based on the data provided, it's not clear the current and forthcoming technologies do/will even fully overcome the ~10x wear factor. Even if they did, as long as any starting wear exists ESS carries a wear penalty (i.e. ~10x more engine starts will still cause more engine wear and shorten engine life relative to 1x starts on the same engine).

Absolutely.

What isn't clear is what a 10X reduction actually means. Can the motor still cover a million miles? Half-million? What is acceptable to be considered "long-term", and does ESS actually reduce this? Or will the cost of gasoline skyrocket and keeping a ICE engine functioning will depend more on it's fuel economy than overall lifespan?

ESS (or whatever it's called) isn't exactly new technology either: https://en.wikipedia.org/wiki/Start-stop_system#History

What I’m saying must be the truth , it really got some E Torque/ESS lovers upset. Only the truth can do that. ? the truth just sounds different and people know it.

As someone who doesn't own one you're in every thread that mentions etorque telling us how terrified of them you are. It's just weird. You have an obsession. Maybe get counseling? If you're that afraid of fca/ stelantis electronics, you should be aware your Jeep isn't safe long term either. We were planning to keep the 2019 long term with its etorque 2.0t but 2 years ago after 60k trouble free miles it was stolen. Our 2022 3.6 has etorque and just passed 30k. I have 0 fear of the etorque and once their out of warranty just like early prius, Ford, etc mild hybrids their will be aftermarket packs available in the $700 range. The only reason you don't see them now is there no market as almost all are still under warranty. Even if it's $2k after 8 plus years that's less than I spend on a set of tires, I think I'll be OK.

His profile also says he just joined the forum less than two months ago, mid Dec2023.

I get it your pro E torque. Keep your vehicle, long-term. Be our long-term tester. Put your money where your mouth is and keep your vehicle long past the warranty. Which will never happen. And stick around the forum so we could have this conversation in five years. Good luck.

“Does stop-start wear out my engine?
When it comes to durability and long life, all the bases relating to the starter gear itself should be covered, but the higher number of stop-start cycles lead to increased engine wear.
“A normal car without automatic stop-start can be expected to go through up to 50,000 stop-start events during its lifetime,” says Gerhard Arnold, who is responsible for bearing design at automotive component manufacturer Federal Mogul.
“But with automatic stop-start being activated every time the car comes to a standstill, the figure rises dramatically, perhaps to as many as 500,000 stop-start cycles over the engine’s life.” That’s a big jump and one that poses major challenges to the durability and life of the engine’s bearings.
A fundamental component of the engine and also one of the heaviest is the crankshaft. It’s supported as it spins by a number of precision ground journals along its length running in ‘plain’ main bearings (no ball bearings or rollers, just smooth metal). These are the main bearings and the effect is greater on the bearing at the back of the engine immediately adjacent to the starter motor.

When the engine is running, the crankshaft and main bearing surfaces don’t actually touch, but are separated by a super-thin film of oil, fed under pressure and pumped around the bearing surfaces by the action of the spinning crankshaft. This process is called ‘hydrodynamic lubrication’ but when the engine stops, the crank settles onto the bearing, the two metal surfaces coming into contact
When the engine starts, there’s a point before the two surfaces become separated by the oil film called the ‘boundary condition’, where the crankshaft is spinning, but there’s metal-to-metal contact between the bearing surfaces.

This is when most wear takes place. Fitting stop-start means the boundary condition (and metal-to-metal contact) could exist perhaps 500,000 times in the life of the engine instead of 50,000 and normal bearings would wear out long before that.”

I've heard that when a 392 kicks back n forth from a 8 cylinders to 4 when its on a hwy that the change is drastic, worse than ess turning off and on.
Keep us informed.
