Prius c is designed with Whiplash Injury Lessening seats for the driver and front passenger and employs a Minimum Intrusion Cabin System where the car's structure is designed to absorb impact and disperse its energy during an accident.

High-Tensile Steel and Safe-T-Cell structure

High-tensile steel gives the car maximum strength with minimum weight. While in the event of a front-end collision, Toyota's Safe-T-Cell structure is designed to disperse the impact energy away from passengers through the upper and side members to the side doors and peripheral framework of the floor.

In a side collision, the impact is designed to be dispersed away from the passengers to the front floor cross member.

Energy-Absorbing Materials

Energy-absorbing materials inside the door trims also help absorb crash energy from side impacts and there are additional energy-absorbing materials to protect chest and HIP areas, while the roof structure is designed to help protect the head area of all occupants.
