China's EV Transition Is Four Different Transitions

China’s electric vehicle adoption is not a single linear curve but rather four distinct transitions unfolding at different speeds across urban buses, passenger cars, heavy trucks, and intercity coaches. New analysis indicates that while urban buses have reached saturation, other segments are driven by varying economic and infrastructure factors.

What Happened

China’s urban bus sector has moved beyond initial adoption to a phase of routine replacement. According to the International Energy Agency, nearly 70% of China’s more than 680,000 electric buses were deployed before 2020, meaning current procurement focuses on renewing older electric fleets rather than converting diesel vehicles for the first time. This shift is supported by China’s 2025 equipment-renewal programme, which continues into 2026 and facilitates the replacement of new-energy city buses and traction batteries.

In contrast, the passenger car market reached a different milestone in 2025, with electric vehicles accounting for just over half of new car sales. The IEA estimates that nearly 70% of battery-electric cars sold in China were cheaper than comparable conventional vehicles even before incentives, normalizing electric propulsion as a standard choice among the nearly 700 available models.

Heavy trucks are experiencing rapid growth in market share, reaching approximately 29% of Chinese sales in 2025, which is roughly double their 2024 share. This acceleration is concentrated in ports, mines, steel plants, and industrial logistics operations where predictable routes and high utilization improve the commercial case for electrification.

Intercity coaches, however, remain at a much lower electrification level, comprising only about 10% of Chinese coach sales in 2025. Despite strong sales growth from the previous year, the coach segment faces structural headwinds from China’s extensive high-speed rail network, which exceeded 50,000 kilometers by the end of 2025 and carried more than 4.5 billion passenger trips during the year.

Why It Matters

The divergence in adoption rates across vehicle categories suggests that national EV market share percentages are increasingly misleading as a sole metric for evaluating transition progress. Urban buses electrified early because battery technology matched their fixed-route duty cycles and public procurement could coordinate charging infrastructure. Passenger cars followed as battery costs fell and model variety expanded, making them competitive with internal combustion engine vehicles.

For heavy trucks, the business case is strengthened by high utilization rates, where lower energy and maintenance costs yield faster returns compared to private cars that spend significant time parked. Conversely, the slow electrification of intercity coaches is not necessarily a failure of technology or policy but a result of modal competition. High-speed rail effectively captures many long-distance passenger trips that might otherwise have been served by buses, particularly on dense corridors where rail offers superior performance.

This dynamic implies that policymakers should not assume all transport segments will electrify at the same pace. Instead, public spending could be more effective if targeted at sectors where electrification aligns with existing economic incentives and infrastructure capabilities, such as depot-based fleets and fixed-route transit, rather than subsidizing every category equally.

The Bottom Line

China’s transport electrification is maturing into a complex ecosystem where urban buses are in a replacement cycle, passenger cars are mainstream, heavy trucks are accelerating in specific industrial niches, and coaches remain limited by the dominance of high-speed rail. The data indicates that the future endpoint is not a single smooth adoption curve but multiple transitions driven by the specific work each vehicle performs and the surrounding transport infrastructure.
