Discusses two approaches to the problem of car safety in crash impact. The first is connected with the accurate measurements of the load-displacement characteristics of typical automotive longitudinal beams in dependence on the high strain rate material properties and effects of wave propagation. The second one concerns a liquid jet crash energy absorber that shows a smooth energy absorption characteristic and might stop an impacting car over a short stroke with a nearly constant deceleration. A practical prototype has been tested which might be integrated in the present longitudinal beams.
