@ShadowsPapa shared some studies that proved 2-3 MPG could be gained through the use of the ESS. Either way, not worth it in it's current state.I could be wrong, but I'm fairly certain that ESS is not designed to improve fuel economy. I've seen reports that it has little to no impact on fuel economy. What it was designed for is to lessen emissions. The engine doesn't run at idle so it's not polluting.
Having said that, Jeep's implementation leaves a lot to be desired.
