The Dodge Grand Caravan and Chrysler Town and Country were redesigned for the 2001 model year.
The Insurance Institute for Highway Safety has evaluated the crashworthiness of the Grand Caravan in three 40 mph frontal offset crash tests into deformable barriers. After the first test, DaimlerChrysler indicated the results were different from tests the company had conducted and requested a retest.
Results of the second test were more consistent with company test results for structural performance, but the amount and pattern of intrusion were similar. More significantly, a fuel leak occurred, revealing a weakness in the design of a circular fitting where the fuel lines exit the fuel tank. Further examination of the fitting in the van tested first showed stress fractures in the same area as the leak in the second van.
A third test was conducted after DaimlerChrysler made a design change to fix the fuel tank fitting and retrofitted a 2001 model with the redesign (all 2002 and later models include the modification). Examination of the redesigned fitting after the third test indicated no damage.
Measures taken from the neck and chest in all three tests indicate low risk of injuries to these body regions in a crash of this severity. A high acceleration occurred when the dummy's head hit the steering wheel through the airbag in the first and second tests, indicating that injuries to the head would be possible. Forces on the left femur indicate that injuries to the upper leg would be possible in the first and third tests. Forces on the right tibia and foot indicate that injuries to the lower leg and foot would be likely in all three tests.
Restraints and dummy kinematics
Dummy movement was well controlled in all three tests, except there was too much upward steering wheel movement in the second test.
