There appears to be a lot of misunderstanding about what eTorque is, and misinformation about what it does.
FCA has done a terrible job explaining and marketing eTorque. Let’s face it, in the absence of understanding, the Internet is filling the blanks, often erroneously.
Found this on another Wrangler forum.
Basically, eTorque provides six functions:
This YouTuber has a Chrysler engineer explain eTorque on a Ram pickup, but the system on Wranglers is the same.
PS - The engineer does a great job of illustrating how much gasoline a 5.7HEMI burns at a 90-second stop.

Basically, eTorque provides six functions:
- Stop-Start: Unlike ESS, which uses the abrupt starter, eTorque uses a 48V battery and belt-starter generator to re-start the engine within 400 milliseconds.
- eRoll Assist: when starting to move, eTorque gives the first half tire rotation a "push" down at inefficient low engine revs to get the vehicle moving.
- Upshift Rev Matching: when the engine needs to upshift, eTorque scrubs off engine speed to rev match for a smooth shift, and stores that energy in the 48V battery instead of using the transmission clutches to scrub off that speed.
- Electronic System power: the 48V battery is used to power the vehicle electrical loads so that the engine doesn't have to cope with the parasitic loss.
- Downshift Rev Matching: eTorque accelerates the engine for smooth shifts instead of using extra fuel.
- Regenerative Braking: under coasting or normal braking conditions, eTorque puts a load on the engine and uses the BSG to store energy that would normally have to be absorbed by the brake pads.
