ARLINGTON, Va. --- The Insurance Institute for Highway Safety announced that the Toyota Tundra, which was redesigned for the 2007 model year, earned good scores in recent frontal crash tests. Two tests of the Tundra were conducted, one by the Institute and one by Toyota. The Institute tested a 2wd double cab, and Toyota tested a 4wd double cab. The overall rating of "good" is based on review of both tests. Dummy movement was well controlled in both tests. During rebound in the Institute's test, the dummy's head hit the roof rail, the Institute said. In each test, measures taken from the neck, chest and one leg indicate low risk of injuries to these body regions in a crash of this severity. Forces measured on the left tibia in the Institute's test indicated that injuries to the lower leg would be possible, but right leg/foot forces were low. (In the test conducted by Toyota, left leg/foot forces were low, but forces on the right foot indicated a possibility of foot injuries.) A high head acceleration occurred when the dummy's head hit the steering wheel through the airbag in the Institute's test, indicating that head injuries would be possible. (In the test conducted by Toyota, the head also hit the steering wheel through the airbag, but the head acceleration was low.) Head acceleration from the roof rail hit in the Institute's test also was low.
