Push the 2wd and it will stay in sport mode, but only.2 wd.... its with any that have ADV 4X4Over the last couple years there has been several discussions about 4A, along with all the "rules" about using 4x4 in high traction environments (like the street).
I've even contributed to multiple threats about 4A where the thought process was that it's in two-wheel drive unless it's senses slippage and then it kicks into 4 wheel drive.
This is not the case and Ford has seemed to have reinvented physics
All of us that have SPORT mode know that 4A engages with this GOAT and it is specifically designed for the street. Now that goes against the "No 4x4 on street" rule. However with the mentality that the 4A/4H doesn't kick in until it needs to, it should not be an issue.
Well I've been playing around with 4A and watching the "power distribution" and a bunch of us, including myself, we're wrong with our assumptions.
4A basically has the vehicle in 4x4 mode pretty much the entire time. There are some inconsistencies, but the only time that I've seen it NOT applying power to all wheels is when off the throttle, or I think, if you have the steering significantly turned BEFORE applying throttle.
To give you some examples, going 75 mph down the freeway and giving it some throttle = 4 wheel drive
Throttling while going through twisty turns on a mountain road = 4 wheel drive.
To me the scariest.... Doing a U-turn at a light (which requires throttle) = 4 wheel drive.
Like I said, there have been a couple of situations when I was testing, and if I turn the steering wheel significantly Before applying the throttle, it seems = 2 wheel drive.
I don't get me wrong, I love the feel of basically AWD... It's been storming (rain) all week where I live, and in 4A, the Bronco has been planted and not a single wheel slip.
I just hope Ford design this correctly and taking windy roads in sports mode isn't going to break something.
We've seen this guy before. If he's a mechanic, then I'm an astronaut. If you figure out which dealership he works for, let us know so we can stay far, far away. I don't want this guy anywhere near my Bronco.Here is a good tear down from a mechanic on the Bronco transfer case (and is very anti-4A).
(skip to 16 mins to see how the clutch is activated). I think towing with the transfer case in 4A is the reason for the clutch replacement.
Also here is animation from Borg-Warner on how the transfer case works:
Watching the two vids suggests that to get any sort of torque bias other than no-connect/lock is to operate the clutch in the slipping region. Now maybe Ford programming does not do this, in which case they are just engaging/dis-engaging the front axle based on inputs (throttle, steer angle, ABS, etc), but not doing any kind of torque-bias like other AWD systems.
Btw the clutch is a wet-clutch so can handle the "slipping region" better than a dry clutch.
100% agree. Sport mode in 2H is the way to go-great power, response and feel. It's my favorite combo....Why not just put it back in 2H? That’s how I use Sport.
Dundee Ford in Illinois. Guy is an absolute hack.We've seen this guy before. If he's a mechanic, then I'm an astronaut. If you figure out which dealership he works for, let us know so we can stay far, far away. I don't want this guy anywhere near my Bronco.
I will have to watch how 4A operates on this. On my F-150, you put in it 4A and it only engaged the front if slippage was detected. I thought that was how this operated.Over the last couple years there has been several discussions about 4A, along with all the "rules" about using 4x4 in high traction environments (like the street).

Interesting on the Wildtrak that Sport also engages 4A. My Bronco Raptor, Sport does not engage 4A. It stays in 2H on the goat dial and on the power distribution screen. I can elect 4A in sport mode if I want to.HOW DOES FOUR-WHEEL DRIVE WORK - ADVANCED 4X4
WITH 4A MODE
Advanced 4x4 With Automatic OnDemand Engagement (If Equipped)
This system monitors various vehicle sensory inputs to provide an increased level of performance. This system offers the driver two-wheel drive high, four-wheel drive auto, four-wheel drive high, and four-wheel drive low as available modes of operation. When you select four-wheel drive auto, the system continuously varies power to the front wheels for optimum performance for all on-road conditions.
That was my point, this is not true. In fact it's the opposite. In 4A the Front is always engaged and only disengages in certain situations (like off throttle and hopefully binding)You are misreading the displays for sure. 4A is in fact just like any other all wheel drive vehicle like my X4 rear wheel drive always and only engages front when slippage occurs. These are not intelligent like Subaru or Honda.
