Moderate overlap front

Rating applies to 2008-10 models

Tested vehicle: 2008 Smart Fortwo Pure 2-door

The Smart Fortwo was introduced in the 2008 model year. As its name implies, the Smart accommodates only two people; there is no rear seat.

Driver restraints and dummy kinematics

Action shot taken during the frontal offset crash test.

The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained very well.

Forces on the dummy's head were high when it hit the steering wheel through the airbag.

Forces on the right lower leg were high enough to indicate the possibility of injuries.

Side

Rating applies to 2008-10 models

Tested vehicle: 2008 Smart Fortwo Pure 2-door with standard front seat-mounted combination head and torso airbags

The Smart Fortwo was introduced in the 2008 model year. As its name implies, the Smart accommodates 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.
