Moderate overlap front

Rating applies to 2007-12 models

Tested vehicle: 2008 Mazda CX-7 Grand Touring 4-door 4wd

The Mazda CX-7 was introduced in the 2007 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.

A high head acceleration occurred when the dummy's head hit the steering wheel through the airbag.

Intrusion into the driver's space was minimal, and all leg and foot injury measures were low.
