FAD fuel economy savings numbers?

[kansasboy91]

I’ve honestly tried to find the actual numbers on what the FAD is supposed to provide in savings. I understand how it works and can see how it would be beneficial though, I would prefer manual hubs. I’m just curious on the supposed savings in mpg I do understand that real life may be different.

Thanks!

Only people with that info work for Stellantis and they’re not sharing. You’d need to run the EPA mileage test protocol with the FAD active and then deactivated and compare. If you go this route, please report back with your findings. I’m mildly curious myself, but not enough to run the experiment.

I wouldn't know. I average 12.7 MPG!
