Am I seeing this right? You ran a ~13.5 second quarter mile with this thing?

If only the edge shifted like the Macan

Backpressure Important in turbo cars however modifying anything after the DP usually has very little effect on it.

Youtube open diff burn out Most likely spinning just one tire. Easier proof... find some snow, turn off traction, floor, have friend with beer watch/videotape, profit As soon as any one wheel breaks traction all of the torque will go to it and the others are sitting there still...

No way you're 'lighting up' all 4 tires with open diffs 2 at most :D

I'll give it a shot when I get home today. It ONLY does it when parked on an un-even surface though, never had the issue on a flat spot.

This has been annoying me for a while. Doesn't always happen, seems to only happen when the car is on an un-even surface. Dealer said they can't repro and have no clue what I'm talking about. Vid here: http://1drv.ms/1NM6OI0

Did a field test with the edge during a snow storm here in the PNW last Saturday. I gotta say I am very impressed. This was with the stock all seasons although I just swapped to some Blizzaks, will probably be awesome now. Car handled well, accelerated, didn't loose tracking and had no trouble digging out of a foot of snow. Whatever they use to controls these open diffs definitely works well in real life applications.

In a true open diff (which I'm told the Edge is) the power goes to the least path of resistance. Meaning, you take one wheel off the ground and 100% of the power will go to that wheel resulting in that wheel spinning and the other sitting still on the ground. By applying braking to the spinning wheel you are effectively sending some power to the other wheel thus making the car move. In a limited slip diff the differential never allows 100% of power to go to one wheel thus even with one wheel off the ground the other will always still get some power. In a torsen or clutch type diff this is further limited and controller by clutches which can vary how much power goes where. All three will behave almost identical if all wheels have traction, differences come up when that isn't true. Imagine the three in a race track type scenario. Obviously braking while going around a corner to send power to the wheels with most traction won't yield the best results as you're doing counter work to the engine's work This is why LSDs or better yet torsen/clutch type diffs are best for sports cars. Controllable differentials (such as clutch type) are able to be adjusted by the ECU when it detects all kinds of things (forces, turn angle, traction slippage, etc, etc) and thus are the best at putting the power down. This is why in the Edge the AWD readout never moves left to right because it simply doesn't know and is not able to control that aspect. Wondering what type of center differential it uses though...?

Bummer. I personally don't like open diff AWD systems, they just don't put the power down the way a true AWD system does. Gonna miss my STi torsen diffs, nothing like throwing that set-up into a corner and powering out

Does anyone actually know how the 2015 Edge AWD system is built? I was looking at my readout on the dashboard during some icy driving and could only see power being distributed front to back, never left to right. Does this thing use limited slip diffs with wheel breaking applied as needed? Can't seem to find any technical specs on it. Thanks! Luke

This one is finicky for me too. Sometimes it doesn't seem to recognize my touch at all, other times it locks when I want it to unlock. Does locking it actually arm the alarm as well? I'd say I have a 7 out of 10 success ratio of getting into my edge without any issues or hicks ups Passengers getting in on the other side, especially new to this feature, are probably closer to 2 out of 10....

I hope you guys are right. I sure hope this drivetrain and internals are able to hold up to extra power. Given my past experiences I'm going to let someone "test" this for a little bit before pulling the trigger though :D Perhaps having two extra cylinders does actually make the forces on each one smaller, plus both my STi motors exploded at around 22-24psi, I don't think the edge runs anywhere near that although not sure. Anyone know the boost increase of the livinois tune? I have no clue what Subaru is doing anymore. They are still running the same failure prone engine even in the newest STis....

DP + Intake should do wonders. However, I somehow worry about breaking things. Looks like just the tune itself adds ~100hp at the crank. That's 33% more power than the car was designed for. Wonder how the rest of the drive train as well as engine internals hold up. Would be interesting to see the oem vs tune boost targets. Having imploded 2 STI motors in the past I'm a little edgy about pushing that much more through the edge.

Sweet! That's not what the dealer told me but really good to know +1 for having two sets of rims/tires.
