Moderate overlap front: original test

Rating applies to 2006-10 models

Tested vehicle: 2006 Ford Explorer XLT 4-door 4wd

The Ford Explorer and Mercury Mountaineer were re-engineered for the 2006 model year. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Ford.

The moderate overlap frontal crash test ratings also apply to the Explorer Sport Trac, which was redesigned for the 2007 model year (no 2006 model Sport Trac was available). The Sport Trac is very similar to the Explorer, except that it has a longer wheelbase and an open cargo bed behind the occupant compartment in place of the Explorer's enclosed cargo area with optional third row seat.

About the original moderate overlap front test

Side: original test

Rating applies to 2007-10 models

Tested vehicle: 2007 Ford Explorer XLT 4-door 4wd with standard front seat-mounted torso airbags and optional front and rear head curtain airbags

The Ford Explorer and Mercury Mountaineer were re-engineered for the 2006 model year. All 2006-10 models have standard side torso airbags; beginning with 2007 Mountaineer and 2008 Explorer models, head curtain airbags were also made standard.
