This video makes me all warm and fuzzy inside.

good video

@popra007 Try driving the locked diffs on pavement. If you want your car to dominate on low-friction surfaces, then weld your diffs, good luck with that on pavement. Subaru has spent a lot of time making sure their off-road awd system still works great on pavement. Also, check your price points.

very impressive; I'm buying a WRX soon

I recently bought a subaru forester and didn't know how good of a vehicle I had until I started watching these roller test videos...you guys that don't own a subaru and only have negative comments about them are just jealous that you don't own one and don't like the fact that the car you have has a crappy FWD or AWD compared to the subaru...

[popra007]

That wasnt an onorable climbing for that Subaru, and no words obout the other attempts of AWD cars.....if u want to see a car that will realy take the 1 wheel grip test, than test any Merceds G-wagon with all differentials locked :P

actualy a hydraulic drive would LACK any kind of clutch, or gears.

so supposedly it would only have the loss of hydraulic pump, and hydraulic motor.

if both are properly sized they preform around 90% efficient.

not to mention it could with cariable geometry allways keep the engine load to optimum economy -or performance-, same for engine revs.

And probably it would be lighter than the bulky trany and clutch, and diffs.

i do agree it would have its costs.

@goglesux

A hydraulic drive system may be a cool idea but I can think of many reasons why it is not used.

*It would be horribly inefficient (The main reason why standard autos are less efficient than manuals is due to the torque converter, a fluid coupling that has fluid frictional losses)

* It would be prone to leaks and a leak would seriously effect drivavbility

* It would be a hanous system to bleed or perform fluid changes

* It would be expensive - Hydraulic stuff isnt cheap

[donkeytits1]

Also traverse engine mounting does not induce torque steer - as long as the drive shafts are of equal lengths and thickness.

Also, these systems do not have all this proprietary secrecy surrounding them, all you need to do is dismantle them or look at the parts FICHE to understand whats going on. The only difficult part is working out the exact behavior of the electronic controls.How they work mechanically, and the normal torque distribution (with out traction control intervention) is easy

[donkeytits1]

Cool objective test and a good way to compare the cars but cometary is full of shit.

* Torque steer is a real phenomenon and is caused by unequal drive shaft lengths. It is only experienced however when a very large torque is applied to the front wheels, such as in powerful front wheel drive cars under hash accelleration. In this test both front wheels are on rollers so it is only possible to apply negligable torque to the front wheels, far less that normal driving. So, no torque steer

@97stscaddy Toyota removed the viscous from the center differential. MF2AV to just MF2A.

I think it started when the 3.3 liter V6 & 5 speed automatic replaced 3.0 V6 & 4 speed auto.

The should leave the hardware traction control on.

would have been nice to se the passat b6 versus the older b5, because the passat b5 had a symmetrical drivetrain layout and a torsen diff
