Moderate overlap front: original test

Rating applies to 2005-07 models

Tested vehicle: 2005 Chevrolet Uplander van

The Chevrolet Uplander, Pontiac Montana SV6, Buick Terraza, and Saturn RELAY were introduced in the 2005 model year as replacements for the Chevrolet Venture, Pontiac Montana and Trans Sport, and Oldsmobile Silhouette. (A limited number of Chevrolet Ventures and Pontiac Montanas were produced for the 2005 model year.) The Pontiac Montana SV6 was discontinued after the 2006 model year, and the Buick Terraza and Saturn RELAY were discontinued after the 2007 model year. The Uplander was discontinued after the 2008 model year.

Driver restraints and dummy kinematics
Dummy movement was reasonably well controlled. However, the dummy's head bottomed out the airbag and hit the steering wheel. During rebound, the dummy's head hit the B-pillar and roof rail.

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 hit the B-pillar, roof rail, and head restraint during rebound. Head acceleration from the B-pillar hit was high.

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