The Life Journey of a Car: From Design to Recycling

A car's lifecycle spans distinct phases:

1. Design & Engineering: Concept → CAD → clay model → wind tunnel → prototype → testing (crash, emissions, durability). 3–5 years.
2. Manufacturing: Stamping (body panels), welding (body-in-white), paint shop (electrocoat, primer, base, clear), assembly (powertrain, interior, trim, electronics). Hours per vehicle; just-in-time supply chain.
3. Distribution: Rail/truck to dealer; pre-delivery inspection.
4. Retail & Ownership: Sale → registration → maintenance (scheduled: oil, tires, brakes; unscheduled: repairs) → possible resale (private/dealer/CPO). Average ownership: ~8–12 years.
5. End-of-Life: Depollution (fluids, battery, AC gas) → dismantling (reusable parts: engine, transmission, electronics, body panels) → shredding → material separation (steel, aluminum, copper, plastics) → recycling into new products.

Modern circular economy goals: >95% material recovery; design for disassembly; EV battery second-life/reprocessing.
