All-wheel drive AWD vehicles often have an electronically controlled coupling system in the transfer case or transaxle engaged ( active part-time AWD ), or locked-up tighter ( in a true full-time set up driving all wheels with some power all the time ) to supply non-slipping wheels with ( more ) torque.

The true extent of the road network is not completely known, since the Spaniards, post conquest, either dug up the road completely in some areas, or allowed it to deteriorate and fall into ruin under iron-clad horses ' hooves, or the metal wheels of ox-carts.

Another difference is that the Aerostar's unique Dana TC28 transfer case employed a true center differential, though this center differential was regulated by an electronically controlled electro-magnetic clutch ; this means that all four wheels are essentially powered at all times.

The major mechanical difference between the Legend and the Toyota, Mazda and Nissan sedans was that the Legend was front wheel drive, which Honda stated was " quite simply the most logical means to the ends the engineers desired: a true luxury car with a low, aerodynamic hood ; a spacious interior with a nearly flat floor, and the superior traction that results from placing the engine and drivetrain transversely over the drive wheels.

The effect relies on a motion perception property called beta movement: motion is seen between two objects in different positions in the visual field at different times providing the objects are similar ( which is true of spoked wheels — each spoke is essentially identical to the others ) and providing the objects are close ( which is true of the originally 9-o ' clock spoke in the second instant — it is closer to 12 o ' clock than the originally 12-o ' clock spoke ).
