That's not quite true, the engine indeed drives the rear wheels but the
centre axle is a trailing axle,i.e. it has no drive or is in no way
connected to the transmission system.

The artic section can bend to a PHYSICAL 54 degrees before the system
locks up.(The drive and transmission cuts out before the driver has
tied it in knots!). Prior to this of course the on-board computer will
warn the driver of any impending excessive bendyness.

Citaros are fitted with traction control and along with the ABS system
will prevent the center (and the front/rear) axle from loosing grip.
Again any traction loss or excessive wheel spin is flagged up on the
drivers display.
