The size of BYD's factory

Scale and Nature of the BYD Site

• Commenters are struck by the apparent 2x2 mile scale and density of machinery; some compare it to motherboards or sci‑fi cityscapes.
• There is debate over what’s actually 50 km²: the BYD factory proper vs. the broader “international land port” logistics zone. Some conclude the whole park is ~50 km² while the plant itself is smaller.
• Comparisons are made to BASF Ludwigshafen, VW Wolfsburg, Azovstal, and even airports and cities, raising questions about what counts as “a factory” (land owned, built area, or indoor floor space).

BYD’s Model, Labor, and Product Quality

• BYD is described as highly vertically integrated: batteries, drivetrains, semiconductors, and final assembly, reducing supplier risk and cost but requiring huge footprints and ~900k workers.
• Contrast is drawn to Western auto makers seen as “final assemblers” with long, fragile supplier chains and outsourced design.
• Experiences with Chinese EVs and buses are mixed: some report early BYD buses in US cities as unreliable, others in Europe, Latin America, and Asia say current BYD cars/buses are good value and rapidly gaining share.
• Several note this echoes the trajectory of Japanese and Korean brands: early poor quality, then fast improvement.

Tariffs, Industrial Policy, and Global Competition

• Many expect US tariffs (and possible Mexico-transit rules) to limit BYD in North America but not globally; others emphasize BYD can build locally (e.g., Brazil, potentially Mexico/US) to bypass tariffs.
• Tariffs are explained as consumer-paid import surcharges that protect domestic producers but raise prices and reduce pressure to innovate.
• Some argue protection is needed to preserve domestic manufacturing capacity, jobs, and wartime industrial flexibility; others see it as short-termism that will leave legacy US/EU automakers uncompetitive outside protected markets.
• Discussion references CHIPS/IRA in the US and differing models of industrial policy, with praise for export‑oriented discipline in East Asia vs. “bailouts + buybacks” in US firms.

China’s Energy, Decarbonization, and Overcapacity

• One camp claims China is “rapidly decarbonizing,” citing massive wind/solar build‑out and declining coal share of power generation.
• Skeptics counter with data on huge coal capacity in the pipeline, rising absolute emissions, and argue China is pursuing “as much of everything as possible” rather than true decarbonization.
• Overcapacity in EVs and other sectors is seen by some as strategic (better to have too much capacity than too little); others view it as misallocated debt-fueled investment reminiscent of earlier bubbles.

Cars vs. Transit and Bikes

• Several criticize pouring such capacity into 2‑ton cars to move ~80 kg humans and argue for trains, buses, and bikes as more efficient climate responses.
• Others reply that global car dependence is baked into urban form; EVs are an urgently deployable “less bad” solution while land use and transit reform are slow and politically unpopular.
• Cost–benefit of bike lanes vs. highways is hotly debated; there’s agreement they help in dense cities but disagreement on scalability and economics in car‑centric regions.

Geopolitical and Security Angles

• Some speculate such mega‑factories could be repurposed for military production (e.g., drones) in a Taiwan conflict; others dismiss this as alarmist and note location and dual‑use constraints.
• Broader concern surfaces about the strategic implications of China’s manufacturing dominance and Western de‑industrialization for future power balances.
