Anyone know if the new awd tweaks found in the 2016 rdx were done by software alone, or are there new parts added. I got a 2013 rdx and was wondering if these tweaks will eventually trickle down to 2013-15 rdx vehicles, unless of course the new tweaks also have new parts designed for it?

 

I remember reading on a press release that there is no part changes, it is all electronic. However I highly doubt they will trickle it down at all.
