The jump in diesel prices triggered by the Iran war is expected to accelerate electrification of China¡¯s heavy truck fleet this year, analysts and automakers say, and speed a decline in fuel demand in the world¡¯s largest oil importer.

Electric heavy truck sales grew over the last two years from a niche market to nearly a third of new ?heavy truck purchases in 2025 thanks to government subsidies, cheap refueling and expanding charging infrastructure. Last year¡¯s growth was particularly weighted in ?the ?fourth quarter because buyers also thought the trade-in subsidy program would be ending soon.

New-energy heavy truck sales, ?which are mostly electric, began this year with the same kind of pop, growing 45% year on year to 44,000 units and accounting for more than a quarter of the segment, up from less than 20% of sales a year earlier, according to data provider CVWorld.cn.
