microcar / 2-door hatchback
Moderate overlap front: original test
Rating applies to 2011-15 models
Tested vehicle: 2011 Smart Fortwo Passion 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. Beginning with 2011 models, driver and passenger knee airbags were added and structural changes were made to improve occupant protection in frontal crashes. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Mercedes-Benz, the manufacturer of the Smart,.
