Tested vehicle: 2004 Lexus RX 330 4-door 4wd

The Lexus RX 330 was introduced in the 2004 model year as a replacement for the Lexus RX 300.

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 very well.

Smeared greasepaint indicates where the dummy's head slid along the roof rail and grab handle during rebound. Head acceleration from this hit was low.

The RX features an airbag that deploys from the knee bolster underneath the steering column. The dummy's knees and shins hit this airbag as indicated by greasepaint.
