The most important fact in the global auto industry right now is also the most boring one to say out loud: in 2025, China built 73% of the 22 million electric vehicles manufactured worldwide. It also bought 60% of them. There is no parallel in any other major industrial category — not consumer electronics, not solar panels, not batteries — for a single country to dominate both the supply and the demand of a foundational product so completely.

BYD is the headline of that story. The Shenzhen-based automaker sold 4.6 million vehicles in 2025, of which 2.257 million were pure EVs — a 27.9% jump year over year. For the first time, that pure-EV number beat Tesla's 1.636 million deliveries. The same company exported 3 million vehicles in 2025 (up 70% from 2024) and April 2026 alone saw a 40% year-over-year jump in BEV shipments.

What got BYD here

BYD is the most vertically integrated car company on earth. It makes its own batteries (Blade), motors, power electronics, automotive glass, even the seat leather. It started as a rechargeable-battery company in 1995, pivoted to cars in 2003, and spent twenty years building the supply chain the rest of the industry was busy outsourcing. When the EV transition arrived, BYD was the only major OEM that didn't have to scramble for a battery partner — it had been one for decades.

The Chinese government's role is the part Western coverage still struggles to describe accurately. Industrial planning for new-energy vehicles was written into the 10th Five-Year Plan in 2001. By 2010, sixteen cities had been selected as pilot EV markets with direct purchase subsidies. By 2015, charging-infrastructure rollouts were being coordinated at the provincial level. The result, twenty-five years later, is a domestic market large enough to fund world-class scale and an export base large enough to threaten every incumbent automaker on the planet.

The price war

In March 2026, BYD cut the price of its Song Pro DM-i Glory Edition SUV by RMB 20,000 (about $2,780) to a starting price of RMB 109,800 ($15,250). NIO followed within a week. Tesla cut Model 3 prices in China by 4%. Geely, Chery, and Great Wall all adjusted. Lithium carbonate prices are at a multi-year low, raw-material deflation is real, and the price war is the only way any of these companies can keep growing volumes in a saturated home market.

The pressure on the rest of the world is acute. A BYD Atto 3 (the brand's compact electric SUV) sells in Europe for roughly €32,000. A directly comparable Volkswagen ID.4 starts at €45,000. Stellantis, Europe's largest OEM by volume, has reportedly told suppliers to expect 20–30% cost-down requirements on EV components over the next 18 months to stay competitive with Chinese imports.

What the incumbents are doing

The responses fall into three buckets. The first is tariffs: the EU imposed countervailing duties of up to 45% on Chinese EVs in late 2024, the US effectively banned them via the 100% Section 301 tariff, and Canada matched the US in 2025. The second is joint ventures: Volkswagen has invested in XPeng, Stellantis has invested in Leapmotor, Audi has a development partnership with SAIC, and Ford is exploring a Chinese partner for its next-generation affordable EV. The third is retreat: several Western OEMs have conceded the sub-$25,000 segment to Chinese brands entirely and are focusing R&D dollars on higher-margin trucks and luxury crossovers.

None of these is a complete answer. Tariffs buy time. Joint ventures mean sharing technology with the competitor. Retreat concedes the volume segment that determines brand relevance with the next generation of buyers.

What to watch

Three indicators will tell us whether BYD's lead is structural or cyclical. First, gross margin: BYD's auto-segment gross margin in Q1 2026 was 18.5%, down from 23% two years ago. If the price war forces it below 15% for a full year, the entire Chinese OEM ecosystem becomes structurally unprofitable and consolidation becomes inevitable. Second, the European Union's CBAM (Carbon Border Adjustment Mechanism) in full effect from 2027, which will start pricing the embedded carbon in imported vehicles and could narrow the cost gap. Third, India: BYD's growth in the world's third-largest auto market is currently capped at a few thousand units per year by regulatory friction. If that changes, the addressable market for Chinese EVs roughly doubles.

For now, the scoreboard reads: 73% global manufacturing share, 60% global demand, 40% year-over-year export growth. The number that matters most is the one no one quotes often enough — 73%.
