China's heavy trucks are now mostly electric

Diesel has powered China's big rigs for decades. That's no longer true for most of them. In September, electric trucks made up more than half of China's heavy-truck sales for the first time. That's according to commodity data firm Kpler, reported by Electrek on Nov. 2. China sold 33,100 electric heavy trucks that month. That's up 37% from a year earlier. On the longest hauls, the big rigs that cross the whole country, electric trucks took nearly two-thirds of all sales.

The number comes from Kpler, a commodity research firm that tracks fuel markets, not an automaker with something to sell. That's part of why it carries weight. The firm also makes a specific prediction. It expects this shift to cut China's diesel demand by roughly 230,000 barrels a day in 2026 alone. That's a meaningful dent in global oil demand from trucking. It's a sector that's been slow to go electric compared to passenger cars. There's a real asterisk here, though. The 230,000-barrel figure is Kpler's own forecast, not a result that's already happened. Whether it holds up depends on how 2026 actually plays out.

Does this pace hold as China's freight market evolves? That's the real test. The harder test comes when China's broader freight demand shifts next year. Buyers will have to keep choosing electric over diesel at scale. Watch whether other countries follow. China dominates global heavy-truck manufacturing. Whatever battery and charging technology wins there tends to show up in other markets within a few years.
