Design Principles
"Material selection should balance performance benefits (e.g., weight reduction) with manufacturing feasibility and long-term durability."
This shift in material selection directly impacts the environmental footprint of vehicles by reducing fuel consumption. Designers and engineers must consider the trade-offs in manufacturing complexity, joining techniques, and potential corrosion issues when specifying these advanced materials.
What This Means for Your Design
Making cars lighter by using new materials like special steels, aluminum, or plastics makes them use less fuel. But, these new materials can be harder and more expensive to work with, and they might corrode if different metals touch.
