En ninguna circunstancia real patinarán ambas ruedas delanteras de forma simétrica.
Un saludo.
yo creo que si, mismamente en nuestro caso, si nos toca ir al pueblo en invierno siempre vamos con el 4x4, porque al estar la cuesta nevada las veces que fui con el mio, lo tengo que dejar abajo, porque el civic patina con ambas ruedas delanteras, creo que el ejemplo está bien puesto, un simple "kuga" se ve como si hace ese reparto a las traseras en cuanto las delanteras empiezan a patinar.
Lo mismo es un fallo que al no ser tan facilmente comprobable, muchos usuarios desconocen si lo tienen o no.

REPLY FROM HONDA SWEDEN
The Honda AWD system uses a compact, lightweight and fuel-efficient rear differential. The design requires a certain torque limitation for the device to be able to work effectively in real conditions, but at the same time, it must not exceed the total capacity of the AWD drive.
In real conditions, regardless of the surface, there is a certain amount of friction always available for both front and rear wheels. The AWD system benefits therefore torque between front and rear wheels in order to achieve optimal driving force.
In the roll test non-existent grip is simulated in the front and maximum grip at the rear.
If all the available torque required to move the vehicle forward would be transferred to the rear differential then the limit for the torque of the unit would be exceeded.
If the vehicle continues to run in this state (the front wheels spinning and the rear wheels standing still) the system senses the high speed variation and that the differential clutch slips and reduces the available torque to the rear wheels to prevent overheating. That is why the vehicle moves backward in the video.
In real conditions a scenario like the roll test with such a high difference in grip between the front and the rear wheels is highly unlikely.
In other words Honda does not see that the roll test fairly highlights CR-V’s AWD performance. Teknikens Värld has done a winter test where CR-V was tested on icy roads, as well as steep paths such as a ski slope.
Honda believes that these tests in real environments should be enough to show that the CR-V is a great winter car and would like to stress that there are no known customer complaints on the CR-V’s traction from the Swedish market or in other markets with similar conditions.
On Teknikens Värld’s question whether the update is made, we can with measuring instruments upon request show that for both customers and media.
Since it is important for Honda that customers feel safe and have confidence in ourselves we did an update of the software of all CR-Vs for the Swedish market.
CR-V customers were able to get the software, free of charge, updated at our dealers from April 15 and in production from July 8 in 2013.
Honda CR-V is a global car and has sold over 5 million copies. It is the world’s best-selling SUV* and the sales in Europe is growing steadily, 6 percent in comparison with last year. The CR-V therefore has many satisfied customers around the world.

es practicamente lo que tu dices, que en la realidad, esto no sucede, que la diferencia tan alta de giro entre los dos ejes es muy poco probable, y que lo hacen así para prevenir el sobrecalentamiento del sistema (embrague y diferenciales, entiendo)
Son maneras distintas de ver el "4x4 inteligente", supongo que Honda da preferencia a que el coche esté "detenido" y que no avance ya que las ruedas delanteras tienen cero de agarre y ven absurdo el intentar que las traseras actuen, que por el contrario Ford, con si alante no hay agarre, pasemos el torque a las traseras "a ver si salimos de esta", es mi opinión...
