here's my take on the "what does it do with my driving style" after driving and experimenting the pathy for about a year and a half. while my terms or descriptions of what's happening might not be exactly accurate, this is what the truck FEELS like it's doing to me.
i in no way recommend/advise/condone/whatever any driving styles mentioned below. my take also ONLY applies to the v8 models, but might also be true for the v6s.
if you are a 'grandpa' driver that does nice and easy slow accelerations, takes turns slowly in dry weather and such, 2wd vs auto will make NO difference imo.
if you are very aggressive (like me) then here's what happens:
1 . if you're in 2wd and you stomp (slow rolling or stopped) it, traction control will kick in if you're slow enough and you'll have a loss of power for a sec.
2. if you're in auto and you stomp it, i feel that the ecu detects wot it goes ahead and engages the clutch pack to send power to the front BEFORE the rear even slips. i think they recognized that wot WILL make the rear slip so why not beat it to the punch.
when i want to do a 'off the line' test (on a non-public street of course!) i would put it in auto and traction off. this will allow the rear to slightly slip, and will engage the front. the rear will regain on it's own instead of cutting power/apply brakes.
in rain/wet/slick/non-snow/etc then auto is good for grandpa, and fun for me.
1. for grandpa whenever you're starting off or in a turn and it detects slip, it will cut the slipping tire(s) and engage the front and you'll be none the wiser.
2. for me i like to punch it around said corners or stop/starts with traction -off-. what happens in the corners is the rear will start to slip out and you'll start to power slid around the corner. the trick is not to let off the gas. right about when you have that "oh crap the rear end is sliding out too far" moment the front engages and pulls you right out. it really takes some getting used to.
3. if you have traction on and you do the above the rear will just barely slip out, but no hollywood sliding around corners style.
and btw i don't do this sort of thing when there's traffic around or on a public street. i only "play" when there's no one around. i'm not going to have fun while putting someone else on the road in danger. it's just my first car was a '82 mustang 5.0, so i like to have a fun when it's slick out
