Compatibility Assessment: can the current ADAC MPDB test properly assess compatibility?
Paper i proceeding, 2016
Car‐to‐car compatibility has been an international concern for decades. In Europe a sequence of three large
EU‐funded projects (EUCAR COMPATIBILITY, VC‐COMPAT and FIMCAR) and the European Electric Vehicle
Congress (EEVC) [1‐4] have addressed this issue. While no consensus was achieved in any of these projects, the
FIMCAR project developed an agreed definition for compatibility and proposed a future frontal impact
assessment approach. The FIMCAR proposal was presented, but it was not approved by Global Road Safety
Project (GRSP) or Euro NCAP. The items addressing partner protection were considered to make homologation,
or the consumer information testing, too complicated.
Euro NCAP has recognised the lack of partner protection (structural engagement) in the European frontal
impact assessment and subsequently updated the roadmap for 2020 with the definition of a mobile barrier for
offset frontal impact protection, which is planned to be adopted in 2020. A Euro NCAP Working Group, which is
led by ADAC (Allgemeiner Deutscher Automobil‐Club), is in place in order to develop the new protocol. Following
ADAC announcements , it is expected that the Euro NCAP frontal impact mobile deformable barrier (MDB) test
procedure will be based on the ADAC mobile progressive deformable barrier (MPDB) protocol. Recent
publications of ADAC MPDB test results  indicate that basic agreements of the FIMCAR project w.r.t.
compatibility requirements are not considered in detail. The objective of this paper is to compare the main
findings of FIMCAR with the current developments.
