Stress (in MPa) vs. percent elongation for different steel types and their applications in body structure

Carbon fiber was chosen for the structural function monocoque that makes up the central, load-bearing cell of the chassis, as the material offers the best weight/stiffness efficiency. The monocoque weighs just 65 kg (143 lbs).
X-Wave concept from Visteon/3M (2008) Thinsulate is a mix of polypropylene, which provides the high-frequency noise absorption, and polyester, which makes the material compressible. Applications of Thinsulate have included door panels, headliners, wheel wells, pillars, and instrument panels. For hybrids, it is used in the same locations but also can be applied around hybrid-specific parts such as electric motors, power electronics, etc.
Structure of door panels
Inner door panel (Steel), Outer door panel (Aluminum) Weight reduction at the outer side of the vehicle body enables to concentrate the point of gravity toward the center of the vehicle, contributing to improved stability in vehicle maneuvering. |
