Abstract
A driveshaft using the longitudinal drive line of a motor vehicle has a tubular shaft with end portions and attachment elements which improve energy absorption in the event of a collision. The shaft is adapted to the crash characteristics of the vehicle in question with energy absorption by the shaft being provided in those cases where the energy absorption by the vehicle has reached a minimum value and after a predetermined vehicle deformation travel wherein the level of energy absorption by the tubular shaft is subject to change.
