Passive safety technologies help mitigate injuries to the driver and passengers if an accident should occur. Mazda does not simply comply with the laws of each country and region and NCAP test, but also conducts tests*1 for various types of potential collisions that might occur on the road, and has made steady progress in developing passive technologies to better protect passengers and drivers. Major passive safety technologies are as follows:
*1 Collision test and evaluation, rollover test, roof strength test, etc.
Mazda has developed SKYACTIV-BODY, a new-generation body structure with lightness and high rigidity, by revisiting the basic principles and reviewing every element of the structure, production method and materials.
Multi-Load Path Structure
Disperses the impact of a crash in multiple directions throughout the framework instead of absorbing it at specific portions.
The front and rear bumper beams adopt 1,800 MPa ultra-high tensile steel with the world's highest level of rigidity among mass production vehicles.
Cross-Shaped Front Frame
Based on the characteristic of the crash energy transferred mainly along the ridge lines of an object, the front tip of the front frame was molded into a cross shape, so as to increase ridge lines to twelve from four in a conventional square section. This helps the shock to disperse more widely, improving the energy absorption efficiency.
Cross shape-molded front frame
Mazda uses various methods to reduce injury to pedestrians in the event of a collision.
To mitigate the impact and reduce injury if a pedestrian’s head hits the bonnet, an energy-absorbing space is created beneath the bonnet. An energy-absorbing structure is adopted in various parts, including the bonnet hinge.
Energy absorbing materials are used in the front part of the vehicle which hits pedestrians' knees to mitigate the severity of pedestrian knee injuries, which may seriously affect their ability to walk. Also, stiffening reinforcement is placed at the bottom of the bumper to better prevent a pedestrian's leg from going under the vehicle.
Impact-Absorbing Hood and Bumpers
At certain vehicle speeds, when sensors detect an impact exceeding a defined level, the rear end of the bonnet is raised. This creates a space between the bonnet and the engine which acts to absorb the energy of impact and reduces the severity of head injuries in collisions involving pedestrians. This design has been adopted since July 2012, for sport cars, such as Roadster/MX-5, whose bonnet is set in a low position.
