Electric big rigs now take half of China's heavy truck sales

Electric heavy trucks grabbed 50.3% of China's big-rig sales in September — 33,100 battery-powered trucks in a single month, up 37% from a year earlier. Here's the kicker: the overall heavy-truck market shrank 21%. The electric slice didn't just grow, it grew while everything else slid backward.

That monthly milestone lands four years ahead of Beijing's own plan. Eleven government bodies had targeted 40% new-energy heavy-truck sales by 2030, but the market lapped that on a monthly basis. Through the first nine months of 2026, China sold 226,400 electric heavy trucks, up 64%, for a 38.1% share — nearly matching all of 2025 with a quarter still to go. In tractors, the long-haul rigs that pull trailers, September's share hit 64.5%, and CATL now says new-energy trucks will be half of China's annual truck sales by 2028.

It all comes down to cost. CATL claims about 0.6 yuan per kilometer in savings, while a study from the ICCT and China's CATARC found battery-electric trucks roughly 19% cheaper per tonne-km than diesel in good conditions — an edge they lose at low annual mileage or when battery weight eats into payload. Charging time is the other objection, and China's answer is swapping. CATL's Qiji brand ran about 300 heavy-truck swap stations at the end of 2025, plans 900 by the end of this year and 2,000 in 2027. In August, CATL agreed to pay 2.56 billion yuan (about $370 million) for nearly 25% of Qiyuan Green Power, China's biggest heavy-truck swap operator with more than 1,600 stations; its new standardized packs hold 432 kWh and 513 kWh and swap in about five minutes. CATL is already exporting the model to Europe with Octopus Energy.

For years, the diesel alternative in China was liquefied natural gas — it took nearly 30% of the market in 2024 when gas was cheap. Batteries are now eating it alive. According to Kpler, LNG trucks held a 37% share of heavy-duty registrations in March against 23% for electric; by July, electric was at 47% and LNG had collapsed to 11%, with monthly LNG registrations falling from more than 30,000 to roughly 6,200. China's diesel consumption already peaked, too — Rhodium Group found refinery runs topped out in April 2023, with apparent consumption sliding from 4.7 million barrels per day to 4.0 million by April 2025. Kpler expects a decline of about 230,000 barrels per day this year and puts gross diesel displacement from alternative trucks at about 680,000 barrels per day — roughly 450,000 from LNG and 230,000 from electric. Road freight still grew about 3% through July.

Europe is growing fast from a tiny base. ACEA data shows 5,120 heavy electric trucks registered in the EU through September, up 59.9%, for a 2.5% share. Switzerland sits at 24%, Norway at 14.4%, the Netherlands at 11.1% and Sweden at 10.3% — but diesel still took 91.7% of all EU truck registrations. The US doesn't even publish an official electric Class 8 figure, which says plenty. The best signal is an order for 2,500 Tesla Semis through ZET SCALE, enough to roughly double the electric Class 8 trucks on American roads, and those trucks have yet to be delivered. Against about 230,000 Class 8 sales a year, the electric share is well under 1%, and the ICCT puts the median electric Class 8 tractor at $411,200 versus $172,500 for diesel.

A spring fuel price spike tied to the Iran war pushed some fleets toward electric on its own, but that only explains part of the story. Electric trucks will still be only about 8% of China's heavy trucks on the road by the end of 2026, according to Kpler — meaning every year of 40-50% sales shares compounds the diesel losses from here. SANY and BYD already sell electric trucks in Europe, and CATL is building the swap network underneath them. The open question: how long can Western truck makers keep charging double what China pays?
