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.

Driver restraints and dummy kinematics

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.

About the original moderate overlap front test

Side: original test

Rating applies to 2016-17 models

Tested vehicle: 2016 Infiniti QX50 4-door 4wd

The Infiniti EX35 was introduced in the 2008 model year and renamed the EX37 in the 2013 model year. The vehicle was then renamed the QX50 beginning with the 2014 model year.

Starting with the 2016 model year, the QX50's wheelbase and overall length were increased primarily for more rear seat room. Side ratings are assigned by the Institute based on a test of a 2016 QX50 conducted by Nissan.
