quattro diagonal test.
This shows how the EDS diffbrake system makes the car move out of this diagonal wheel spin. with only open differentials, one front and one rear wheel would spin, and even if the spinning front wheel got contact with the ground, so that both front wheels had traction, the car would NOT move without EDS, because the torsen center diff cannot transfer any torque if one of the axles loses traction completly, as if one rear wheel is off the ground like in this video, then that would be the only wheel that would spin, all others would stand still. So the EDS uses the brake to brake the spinning rear wheel so the other side that has all the weight also gets some torque and add a overall load to the rear axle, making the torsen transfer equal torque divided by the built-in Torque Bias Ratio (TBR) witch i guess is 1:3 on this car, so the front wheels gets the rear wheel torque divided by 3, witch makes the car move.

Highspeed Audi towing Opel Corsa
As I passed these two, I thought they were going much to fast. I saw that he put on his blinker, I quickly got out my camera (because noone would believe me) and this is what I filmed. For those who think I was wrong to film while driving.... the camera used is like a cell phone but smaller than most.... no danger using it!
Electronic Stability Control (ESC) Revealed
The federal government estimates this new technology will save more lives than the airbag!
ESC is so efficient in keeping your car on the road that Farmers Insurance even gives a discount on your auto policy if it is installed on your vehicle!

Audi A8 W12 6.0 Top Speed 295km/h
This is a software upgraded W12 12 cylinder 6.0 liter (366Cubic inches) engine at around 500hp. The run was done on a professionally monitored speedway. The speedometer went beyond the marked area, but would most definitely show about 320km/h. You can compare the speedometer numbers with the GPS numbers - the GPS is precise. The max speed should be around 300km/h (188mp/h)on high octane gas, this run was done on regular gas.
