Lexus ATC vs. Audi Quattro vs. Acura SH-AWD
AWD comparison test at AET (Automotive Enviro Testing) in Baudette,
Minnesota. Audi's Q7 Quattro (TORSEN Torque-Sensing AWD) versus Lexus
RX350 ATC (Active Torque Control AWD) versus Acura's MDX SH-AWD
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.
Audi Quattro plows its own lane in snow
Audi C4 100 / A6 establishing it's own lane in snow while all the lesser
two-wheel driven cars are left to wait for the stuck truck to clear the
Snow drift is not a hindrance for the Audi A6/C4 S6.
This clearly illustrates the potential in Audi Quattro, even an old one
like this 1990s C4 Avant.
There is nothing like a four wheel drive car on winter roads.
