2013 Infiniti M37/M56
large luxury car / 4-door sedan
Award applies only to vehicles excluding M56x 4-wheel-drive models
Small overlap front: driver-side
Rating applies to 2013 models
Tested vehicle: 2014 Infiniti Q70 3.7 4-door
The Infiniti M sedan was redesigned for the 2011 model year and renamed the M37 and M56 because the sizes of the two available engines were increased. A hybrid-electric version of the M, known as the M Hybrid, was introduced in the 2012 model year. Beginning with 2013 models, design changes were made to the frontal airbags and seat belts.
The Infiniti M sedan was renamed the Infiniti Q70 beginning with the 2014 model year, available with V6, V8, and hybrid V6 powertrains. No substantive changes were made with the model name change for 2014. Therefore, the small overlap frontal ratings of the tested 2014 model Q70 also apply to all 2013 M models.

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 reasonably 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.
Except for door hinge pillar deformation and intrusion of the parking brake pedal (not visible), the driver's space was maintained reasonably well, and risk of injuries to the dummy's legs and feet was low.

Moderate overlap front: original test
Rating applies to 2013 models
Tested vehicle: 2013 Infiniti M37 Premium 4-door 4wd
The Infiniti M sedan was redesigned for the 2011 model year and renamed the M37 and M56 because the sizes of the two available engines were increased. A hybrid-electric version of the M, known as the M Hybrid, was introduced in the 2012 model year. Beginning with 2013 models, design changes were made to the frontal airbags and seat belts.
Two moderate overlap frontal tests of the M were conducted by Nissan, one of a 2011 model and the other representing a 2013 model. These cars are rated separately, except that the structure ratings for both vehicles are based on both tests. (The second car tested by Nissan was designated as a 2012 model but included the airbag and seat belt changes of the 2013 models.)
Beginning with 2014 models, the M sedan was renamed the Q70, available with V6, V8, and hybrid V6 powertrains.

Side: original test
Rating applies to 2013 models
Tested vehicle: 2013 Infiniti M56 Premium 4-door 4wd with standard front and rear head curtain airbags and standard front seat-mounted torso airbags
The Infiniti M sedan was redesigned for the 2011 model year and renamed the M37 and M56 because the sizes of the two available engines were increased. A hybrid-electric version of the M, known as the M Hybrid, was introduced in the 2012 model year. Beginning with 2013 models, design changes were made to the seat-mounted side torso airbags to improve occupant protection in side impact crashes.
Two side tests of the M were conducted by Nissan, one a 2011 M37x and the other a 2013 M56x. These cars are rated separately, except that the structure ratings for both vehicles are based on both tests, as are rear dummy injury and head protection ratings, because no changes were made to the rear occupant compartment.
Beginning with 2014 models, the M sedan was renamed the Q70, available with V6, V8, and hybrid V6 powertrains.
