Remarks: During the CLEVER project only the following three crash tests were performed. The aim of these tests was to validate the numerical simulation and to look for possibilities to improve the vehicle.
The tests proved that the concept allows a high occupant safety design and the structure of CLEVER is correct.
Compatibility test
Test conditions: CLEVER with 50km/h against a medium sized car
Dummies: Driver and passenger in CLEVER; driver in the opponent car
Results:
- In the test CLEVER hit the car in the centre of the driver on the driver’s side of the car. All body regions of the driver of the passenger car had only a very low injury risk..
- The compatibility test showed only a minor intrusion into the passenger car because CLEVER did not override the door sill.
- The loadings inside of CLEVER were lower than in the crash against the rigid wall.
Summary:
The overall rating according to the Euro NCAP protocol showed 14 points for frontal and lateral impact. This corresponds to two stars of which one is strike through because of a high injury risk in the frontal impact.
Additional optimisations without major redesigning of CLEVER (according to the improvements mentioned above) will lead to at least 3 stars. Four stars seem to be achievable, too.
