A structural breakdown of Tesla's Gigafactory model — vertical integration, megacasting, structural battery packs, and factory cost per unit — and how it compares to legacy automotive assembly economics.

Tesla's Gigafactory concept — massive, vertically integrated single-campus manufacturing — is the core of its cost advantage. Giga Nevada (batteries, 35 GWh annual capacity), Giga Fremont (vehicles, 600,000/yr), Giga Shanghai (750,000+/yr, lowest cost), Giga Berlin (375,000/yr), and Giga Texas (500,000/yr target) collectively represent the most modern auto manufacturing footprint in the world. Key innovations: (1) Megacasting — 6,000-9,000 ton Giga Presses cast the front/rear underbody as single aluminum pieces, replacing 70+ stamped parts. (2) Structural battery pack — the battery itself becomes a structural element of the car, eliminating the separate floor pan. (3) 48V low-voltage architecture — reduces wiring harness weight/cost by ~70%. Total installed CapEx across all gigafactories: ~$20B. At full utilization, Tesla's cost per vehicle is estimated at $31,000-$35,000, vs $40,000-$60,000 for equivalent legacy factory output. The unboxed manufacturing process under development promises to further cut factory floor space and assembly time by 50%.
