Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

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. Beginning with 2011 models, driver and passenger knee airbags were added and structural changes were made to improve occupant protection in frontal crashes. Frontal ratings are assigned by the Institute based on a test conducted by Mercedes, the manufacturer of the Smart, as part of frontal crash test verification.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Restraints and dummy kinematics

Dummy movement was well controlled. After the dummy moved forward into the airbag, it rebounded into the seat without its head coming close to any stiff structure that could cause injury.
