Acrura and Honda have historically produced some of the worst crash test of any car ever manufactured so I don't really place a great deal of merit on a single test like this.
The F30 is stiffer and stronger than the E90, and passes other tests with flying colours. Maybe there will be adjustments if 'consistent' results show there is a weakness for this type of impact, but until we see more evidence I would take this result with a huge pinch of salt. After all, where were these guys when American cars could not even be fitted with decent headlamps - wasn't that long ago that European cars had to have their halogen headlamps ripped out and replaced with tungsten rubbish just to comply to lighting regulations. Not criticising really - but a sense of perspective is necessary I feel.
