The Smart Fortwo was introduced in the 2008 model year. As its name implies, the Smart seats only two people; there is no rear seat.
During the crash, the driver door unlatched. This opening didn't significantly affect dummy movement during the test but shouldn't happen because, in some crashes, it could allow partial or complete occupant ejection, especially if the occupant is unbelted. This door opening resulted in a structure rating downgrade from good to acceptable.
