The most important test is a crash with deformable, vertical barrier located on the driver’s sight and moved by 40% from the vehicle’s symmetry axis (offset). These are the conditions of typical collision, in which two cars are coming from opposite directions. The model tested by American IIHS organization was equipped ith 1,6l engine and weight 1,150 kg, travelling with 64 km/h hit the barrier with 182,02 kJ. Just to compare – the same model, but with smaller engine 1,4L and weight 1,130 kg, travelling with lower speed of 56 km/h hit the barrier with 136,93 kJ. The speed lower by 12.5% caused the energy reduction by 25%.
Parameters of side impact deviated from standards. The standard test is a crash of movable barrier (weight 1,500 kg) hitting the car with the speed of 50 km/h (145 kJ of energy). In C-NCAP crash tests, the platform hits the car with the same speed, but its weight is 950 kg (91,78 kJ of energy), which is only 63% of preferable value. The pictures definitely show, that there are differences in tests’ parameters and their effects.
