2015 Infiniti QX50
midsize luxury SUV / 4-door SUV
Moderate overlap front: original test
Rating applies to 2014-17 models
Tested vehicle: 2008 Infiniti EX35 Journey 4-door 4wd
The Infiniti EX35 was introduced in the 2008 model year and renamed the EX37 in the 2013 model year because the engine size was increased. The EX was renamed the QX50 beginning with the 2014 model year.

Action shot taken during the frontal offset crash test.
The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained well.
Smeared greasepaint indicates where the dummy's head brushed the side airbag during rebound. The head also hit the roof, sunvisor, and grab handle before moving back against the head restraint.
Intrusion into the driver's space was minimal, and all leg and foot injury measures were low.

Tested vehicle: 2014 Infiniti QX50 4-door 4wd with standard front and rear head curtain airbags and standard front seat-mounted torso airbags
The Infiniti EX was introduced in the 2008 model year and renamed the QX50 in the 2014 model year. Beginning with 2014 models, the QX50 received side curtain airbag modifications.
Three tests of the vehicle were conducted, two of 2008 EX models by the Institute and the third representing a 2014 QX50 model by Nissan. These vehicles are rated separately, except that the structure ratings for both vehicles are based on all three tests. (The vehicle tested by Nissan was designated as a 2011 EX model but included the side curtain airbag changes of the 2014 QX50 models.)
