The Cherokee will bring the vehicle to a full stop if necessary, whereas the Grand Cherokee will only brake for two seconds, the driver must then take over.
The Renegade also has the new system, also fitted to the Cherokee.

Thanks do you have any links that explain it?
Also I suspect IIHS tested an Early MY14 in 2013 which did have an ACC that could not do a Full Stop. It was upgraded around July 2013. The IIHS Report came out in Sept 2013.
I don't think any FCW system does full stop yet. You'd need rear, Radar/Cameras to see what's coming up behind in order to do an emergency full stop.
FYI, 2015 brochures look EXACTLY the same.
This is from the 2015 Grand Cherokee Brochure
Forward collision warning with crash
mitigation (FCW)14 Radar sensors detect when
Grand Cherokee may be approaching another
vehicle too rapidly and send an audible and
visual alert to the driver. The system also
provides 1.5 seconds of braking assistance
if the driver does not react in time. Available.
