In frontal collisions between cars of different mass, the lower mass car will experience a higher velocity change (delta-v) than its opponent, corresponding to the mass ratio. An experimental low mass vehicle (LMV) conceived by the working group on accident mechanics has been modified to withstand an impact of 71 km/h against a deformable obstacle (two stacked Federal Motor Vehicle Safety Standard (FMVSS) 214 barriers mounted on a rigid wall) simulating the opposing (high mass) car. The restraint systems, for instance belts, airbag, kneebolster, and deformable steering wheel, as well as parts of the interior geometry have been adapted using mathematical modelling prior to the test. The aim is to fulfil the occupant safety requirements. Significant conclusions for the design of future LMVs can be drawn. (A)
