ADAC tests deliver well-founded data material providing impressive proof of safety improvements promoted by ADAC.
A prominent example is the rear-end collision between passenger car and HGV. In a series of tests, ADAC was able to demonstrate that the underrun protection system as provided in the EU Directive implemented in 2007 cannot adequately protect the occupants.
In a first crash test, the underrun protection system in line with the new EU Directive was used. The results were not convincing: The passenger car underruns the HGV to a considerable extent. In addition, the rear panel of the HGV pushes the airbags of the car down so that they cannot offer any protection for the passengers. The cabin is completely destroyed up to the rear door. Conclusion: The driver and front passenger are at high risk facing life-threatening injuries. Results of the second crash test with the system optimised by ADAC were clearly better: the underrun protection was reinforced with an additional diagonal support to the HGV chassis and ground clearance was reduced. The impact was absorbed by the underrun protection. Crumble zone and airbag effectively protect the vehicle occupants. While there is still a risk of injuries, life-threatening situations are unlikely to occur!
ADAC’s demands to industry and the EU for improvement of the underrun protection are based on the results of the second test and aim at optimising the protection of vehicle passengers. ADAC has put forward solutions and will promote their implementation.
