1. A steering column for a motor vehicle comprising:
a supporting unit that is connectable to a chassis of the motor vehicle;
a displacement unit that is displaceable relative to the supporting unit along a displacement path in a crash event; and
an energy absorption element disposed between the supporting unit and the displacement unit, the energy absorption element comprising a local laser solidification on or adjacent local areas of the energy absorption element that are configured to preferentially deform and/or tear relative to other areas of the energy absorption element, wherein the energy absorption element is configured to absorb energy over the displacement path in the crash event and wherein the other areas are free of local laser solidification.
