The present invention refers to a sleigh-type structure for impact test bench for complete vehicle with a light design and great rigidity, which main body is made of cast aluminium able to resist and support up to 80 G of acceleration and up to 1600 kg of total weight, which also has a magnificent rigidity in the vertical direction, it also being resistant to high conditions of mechanical stress, resistant to impacts and extra light. The inventive structure comprises: a) a main base of aluminium in a single piece for receiving the body of the vehicle to be tested, b) a low friction rolling-anchoring subsystem for allowing the body of the vehicle to be displaced over the structure rails, this including safety means for preventing the sleigh from coming off the rail due to the impact, c) an impact bumper and d) a coupling member of hyper-elastic material for absorbing the forces resulting from the impact, which is coupled to the impact bumper and the main base by means of screws. The ma in base offers a space for housing the data acquisition systems and transducers for measuring the impact data.
