Abstract: Driver Safety is one of major research area in race car engineering. Researchers are designing advance active and passive safety system to assure the safety of the driver. Development time and cost of any product is reduced by great extend with the use of computer simulated software’s. But the simulated results can’t be used directly into real life without any validation with experimental results. Aim of this paper is to compare the computer simulated results of energy absorbing capabilities of low cost aluminium alloy impact attenuator using LS-DYNA with that of actual drop test performed in the laboratory. The analysis results are found in good agreement with experimental results obtained from crash testing in real time, performed at ARAI, Pune. Average deceleration of impact is less than 20 g as per the requirement of FSAE design rules.
