As the guy mentioned, the tires do look totally bald - unless they're some low-pro racing slicks :rotfl: but maybe that is just the camera...

Hard suspension plus traction control off. The rear tire is in the air.

It's a WRX. The WRX's AWD system doesn't work very well.

I have gone up steeper drives. Hoax video. Or severely modified suspension.
That's not the point.

The WRX has open differential that don't respond well to traction loss.

The traction control should have intervened at that point. It's clearly turned off.

the new wrx's are suppost to have a system that would apply the brakes to that tire in the air, allowing more torque to be applied to the rear axle and as a result to the tire firmly on the ground. ither that system is broke, was disabled on purpose, the video is a hoax, the driver had a heart attack, or subaru lies about this system's existence.

Traction control isn't anything new. It's been around since at least mid 2000s in common use.

The WRX having a "rigid" frame plus the narrowed width driveway entrance, is the reason why the rear passenger tire was lifted. My understanding is when Subaru AWD senses slip, it sends power to each individual wheel with grip? Since the tires seem bald on the front, it couldn't get traction on the "metal" sidewall of the cement sidewalk. It's not a hoax video, and I doubt the driver purposely turned off traction control for everyday driving. Maybe the AWD was disabled due do a fuse problem?

traction control only effects throttle no? i believe they call this torque vectoring or something.
No, it applies the brake to the spinning tire if there is one coupled with cutting throttle.

You can't disable the AWD system on any WRX.

I'm trying to hide my frustrations here, but most people really don't seem to understand how AWD works and why the WRX AWD system is nothing special. I suppose we can thank Subarus marketing for people thinking that "symmetrical AWD" is somehow better.

so this brake actuation as a work around solution to open diffs is in every car with traction control?

Zax. I can hit the traction control button lift a wheel and have the same issue this car has. I've done it in my WRX out of curiosity. With the traction control on the brake is applied and the car does not have the issue. I've done this multiple times. This says that traction control is disabled in some way.

I can further prove it in snow where I can one wheel wonder with the traction control button depressed. I've done it several times and it also does not happen when the system is activated.

Yes, most vehicles today with AWD and open diffs use the brakes as a LSD style device. They brake the wheel that's spinning so there is torque to distribute to the other wheel.

only awd or is it in any fwd or rwd cars too?

also you can disable awd on a wrx, it just takes a little more than a button or fuse to accomplish.
Most vehicles use this in some fashion. Even with an LSD you have to provide some friction to spin the opposite wheel. If you lift the entire wheel off the ground even torsen diffs act as open diffs and just spin the lifted wheel.

I'm very aware of the way that the brakes are used in modern AWD systems. That doesn't change the fact that it is not an effective solution.

why isnt it? on paper it seems like a pretty decent solution to me.

My point was that wheel had almost 0 droop. My stock wheel would have drooped easily and never lost contact with the ground on that slight incline.
