China's auto market has undergone a seismic shift that conventional industry narratives have failed to acknowledge. In 2016, 99% of the country's auto sales were conventional vehicles; by May of this year, that share had collapsed to just 36%.
Framing the debate around "capacity" while ignoring this transition obscures the reality on the ground. Chinese consumers purchased nearly 17 million battery-electric and plug-in hybrid vehicles last year, yet dedicated EV production lines are configured to build only about 15 million units annually.
When factoring in mixed factories capable of producing both conventional and electric models, total EV sector output capacity reaches roughly 25 million vehicles per year. With domestic EV sales projected at 17 million to 20 million units this year, utilization rates would sit at a healthy 70% to 80% even before accounting for exports.
Several fast-growing domestic EV specialists are selling more cars than their factories can produce, a clear signal that production lines are straining to meet demand rather than sitting idle.
The real overcapacity lies elsewhere: among incumbent state-owned enterprises and their foreign joint-venture partners. Having lagged behind private Chinese EV makers in the pivot to battery power, these firms now operate a scattered network of underutilized engine plants.
One major state-owned manufacturer illustrates the divide. Its joint venture focused on compact EVs ran at a 95% utilization rate last year, while its other partnerships centered on internal combustion engine variants of overseas brands operated at just 37% and 55% capacity respectively.
Foreign brand sales in China have declined sharply, but not due to protectionist scheming. The product lines of overseas carmakers, which electrified more slowly in China than in their home markets, simply failed to keep pace with consumer preferences.
One prominent foreign automaker derived just 3.6% of its China sales from electric models last year, far below its European electrification rate. In a market hungry for new EV offerings, combustion-heavy lineups have lost momentum.
The same pattern appears among state-owned marques that might have been expected to benefit from favorable policy. Sales of their own-brand gasoline models have fallen by two-thirds or more since peaking around 2016.
Chinese consumers have not abandoned foreign vehicles — they have abandoned gasoline vehicles. The structural shift is technological, not nationalistic.
Foreign firms are frequently the architects of the excess capacity now drawing scrutiny. One Japanese automaker could produce 1.7 million cars in China in 2023 but sold barely a third of that volume, and continues to hold significant idle capacity in hopes of repurposing plants for export.
This dynamic reflects a normal capitalist process of creative destruction rather than coordinated industrial policy. A radical new technology is uprooting an incumbent one, leaving established firms clinging to obsolete infrastructure.
China's car industry does face excess capacity, but not where critics assume. The country does not have too many EV plants — it has too few.
