I studied this system extensively before getting it on my 2020.
Facts: the eTorgue system uses a belt-mounted generator to charge the LiOn battery. This battery is then used for 1) accessory equipment when the engine is not running, and 2) starting the engine ONLY in the auto-stop setting. It is NOT used to start the engine from a cold start (pressing the start button.)
From driving both I can tell you the single biggest difference is how the truck operates with the start/stop function active. The eTorque system makes it hard to even tell when the engine re-starts. it starts rolling the second you remove pressure from the brake pedal and moves smartly off the line. The MPG boost is entirely in town from the start/stop system. In real world driving for my mix of suburban to urban driving the start/stop system is good for about 100 additional miles per tank.
In theory the eTorque offers no benefit to highway MPG, in fact, it creates some amount of parasitic drag, and therefore might lower highway MPG a little. The 4th gen trucks seem to get better highway MPG overall. I went from about 11/22 to 17/15...ironically get roughly the same number of miles per tank when commuting, but on road trips I cuss this miserable SOB every mile at 15 mpg.
