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

The Mazda 6 was redesigned for the 2014 model year. Beginning with 2016 models, the side curtain airbags were lengthened and the deployment timing for both the frontal and side airbags was reprogrammed to improve occupant protection in small overlap frontal crashes. Because there were no structural changes, the structure rating is based on Institute tests of both the 2014 and 2016 models.

Structure

The driver space was maintained well in both tests considered together. The maximum intrusion of the lower interior was 13 cm at the lower hinge pillar in both the 2014 and 2016 models. Upper interior intrusion measured 6 cm at the hinge pillar in both models and 5-8 cm at the instrument panel in the 2016 model.

Injury measures

Measures from the dummy indicate that injuries to the right lower leg would be possible in a crash of this severity. The risk of significant injuries to other body regions is low.

Restraints and dummy kinematics

The dummy’s movement was reasonably well controlled. The dummy’s head remained largely in contact with the frontal airbag during the crash, but its head still moved toward the A-pillar because the seat belt allowed excessive forward excursion of the dummy's head and torso. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects. The side torso airbag also deployed..

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

The Mazda 6 was redesigned for the 2014 model year. Beginning with 2016 models, the side curtain airbags were lengthened and the deployment timing for both the frontal and side airbags was reprogrammed to improve occupant protection in small overlap frontal crashes. Beginning with 2018 models, the passenger side A-pillar, door hinge pillar, and door sill were strengthened to further improve occupant protection in passenger-side small overlap crashes.

Passenger-side small overlap ratings are assigned by the Institute based on a test conducted by Mazda as part of frontal crash test verification.

Structure

The passenger space was maintained reasonably well, with maximum intrusion of the lower interior of 15 cm at the lower hinge pillar. Maximum upper interior intrusion measured 10 cm at the dashboard.

Passenger injury measures

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

Passenger restraints and dummy kinematics

The dummy’s movement was well controlled. The dummy’s head loaded the frontal airbag, which stayed in front of the dummy until rebound. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects. The side torso airbag also deployed.

Driver injury measures

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

The Mazda 6 was redesigned for the 2014 model year. Two moderate overlap frontal tests of the Mazda 6 were conducted, one by the Institute and the other by Mazda as part of frontal crash test verification. Ratings are based on both tests, but the vehicle specifications shown below are based on the Institute’s test.

Injury measures

Measures from the dummies in the two tests, taken together, indicate a low risk of any significant injuries in a crash of this severity. Head accelerations from the sunvisor, roof, and grab handle hits were low or negligible in the Institute's test.

Restraints and dummy kinematics

Dummy movement was well controlled in both tests. The driver side curtain and side thorax airbags deployed during the crash. In Mazda's test, after the dummy moved forward into the frontal airbag, it rebounded into the seat without its head coming close to any stiff structure that could cause injury. In the Institute's test, movement was similar except the dummy's head grazed the sunvisor, roof, and grab handle during rebound.

Side crash test ratings can be compared across vehicle categories.

The Mazda 6 was redesigned for the 2014 model year. Side ratings are assigned by the Institute based on a test conducted by Mazda as part of side crash test verification.

Injury measures

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

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

Head protection

Driver — The dummy's head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Passenger — The dummy's head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Roof strength test ratings can be compared across vehicle categories.

In the test, the strength of the roof is determined by pushing a metal plate against one side of it at a slow but constant speed. The force applied relative to the vehicle's weight is known as the strength-to-weight ratio. This graph shows how the ratio varied as the test of this vehicle progressed. The peak strength-to-weight ratio recorded at any time before the roof is crushed 5 inches is the key measurement of roof strength.

A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.
