Overview
Rising diesel prices after the outbreak of war in Iran have sharpened incentives for Chinese haulers to replace diesel tractors with electric alternatives, industry analysts and automakers say. The price shock is accelerating a trend that turned electric heavy trucks from a niche offering into a major share of new purchases in 2025, and it is likely to push down fuel demand in the worlds largest oil importer.
Recent sales and market composition
New-energy heavy truck sales, which are predominantly electric, have moved strongly from small-scale adoption towards a meaningful portion of the segment. Last year the market saw a concentrated burst of demand in the fourth quarter as buyers anticipated the end of a trade-in subsidy programme. That momentum has continued into 2025.
Data from CVWorld.cn shows new-energy heavy truck sales rose 45% year-on-year at the start of 2025, reaching 44,000 units and representing more than a quarter of total heavy truck sales, compared with under 20% a year earlier. CVWorld.cn also expects April sales of heavy electric trucks to increase about 30%, citing stronger seasonal demand alongside higher oil prices.
Drivers behind the acceleration
Analysts point to a combination of factors underpinning the shift: government subsidies, relatively low costs to recharge, expanding charging networks and sharply higher retail diesel prices. Retail diesel prices jumped 27% in China after the Iran war began on February 28, climbing to levels not seen since a peak four years earlier. That rise has made the economics of electric heavy trucks more compelling for fleet operators.
Electric heavy trucks typically offer ranges of around 300 km (186 miles), making them well suited to short-haul trips between factories, logistics yards and transport hubs. Manufacturers and some routes are extending those distances: producers such as Sany are marketing models with ranges up to 600 km.
Costs, subsidies and the trade-in programme
Price remains a front-and-centre consideration. Electric heavy trucks in China cost more than 500,000 yuan, while comparable diesel models are priced at over 300,000 yuan. A trade-in programme, which was extended in April to run through year-end, can cut a large portion of that gap for buyers. Beyond purchase price, lifetime cost calculations under current fuel prices favour EVs: GL Consulting estimates that total expenditure on an electric truck over 1 million km - including purchase, fuel and operating costs - is roughly half that of a diesel equivalent.
Impact on diesel demand and consultant forecasts
Widespread electrification of cars together with a rapid rollout of electric and liquefied natural gas-powered trucks have already reversed decades-long growth in diesel and gasoline consumption in China. Most analysts expect Chinas oil demand to peak by 2030, and the recent surge in diesel prices has prompted some consultancies to predict a steeper decline than they had previously projected.
GL Consulting now expects diesel consumption to fall 4.3% this year, compared with its pre-war forecast of a 4.1% drop. Rystad Energy has revised its outlook to a 5% decline this year, up from a prior forecast of a 4% fall - a change equivalent to an additional reduction of roughly 40,000 barrels per day.
Exports and global market positioning
Lower operating costs and competitive pricing are also driving growth in exports. China accounted for about 160,000 electric truck sales in 2024, while Europes market was under 25,000 that year, according to the International Energy Agency figures cited in industry reporting. At least a dozen Chinese manufacturers, including top-selling brand Sany, plan to introduce models in Europe this year at prices as much as a third below the current average there.
Sanys own outlook has been bullish: the company had been expecting an acceleration in diesel-to-electric replacement in 2025 and forecast the electric tractor truck market could grow 50% to reach 250,000 units. Deputy General Manager Chen Dong said rising oil prices have increased the likelihood of reaching that target.
Use cases and limitations
Electric heavy trucks are predominantly deployed on short-haul routes due to typical ranges of around 300 km, although longer-range models and expanded charging corridors are appearing. This operational profile shapes where electrification is most economically attractive today.
Outlook
Higher diesel prices linked to the Iran war have tightened the economic case for electric heavy trucks and prompted revisions to diesel demand forecasts by energy consultancies. Government incentives, trade-in support extended through year-end, falling operating costs for EVs and improving charging infrastructure are reinforcing adoption domestically and spurring exports to markets such as Europe.
