Tested vehicle: 2016 Scion iA 4-door

The Scion iA sedan was introduced in the 2016 model year. It is based on the redesigned 2016 Mazda 2, which is no longer available for sale in the U.S. market.

The Scion iA was renamed the Toyota Yaris iA beginning with the 2017 model year as Toyota discontinued the Scion nameplate. Beginning with the 2019 model year, the "iA" portion of the name was dropped.

Action shot taken during the small overlap frontal crash test.

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

The frontal and side curtain airbags worked well together to keep the head from coming close to any stiff structure or outside objects that could cause injury.

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low.

Tested vehicle: 2016 Scion iA 4-door

The Scion iA sedan was introduced in the 2016 model year. It is based on the redesigned 2016 Mazda 2, which is no longer available for sale in the U.S. market. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Mazda as part of frontal crash test verification.

The Scion iA was renamed the Toyota Yaris iA beginning with the 2017 model year as Toyota discontinued the Scion nameplate. Beginning with the 2019 model year, the "iA" portion of the name was dropped.
