Daimler Truck built its position as the world's largest heavy-truck manufacturer on decades of dominance in Europe and North America, but chief executive Karin Radstrom is now confronting a rival the company has never had to take seriously before: a fast-growing wave of Chinese manufacturers pushing into international markets with aggressively priced electric and diesel trucks alike.

Chinese truckmakers have spent years scaling production for their domestic market, and with demand at home cooling, several are now redirecting that capacity abroad. Brands that were barely known outside China a few years ago are showing up at European trade fairs and winning fleet contracts in Latin America and Southeast Asia, often undercutting established Western manufacturers on price while closing the technology gap on electric drivetrains and battery range.

Radstrom, who took the top job at Daimler Truck after years steering its Mercedes-Benz Trucks division, has responded by pushing harder on electrification rather than retreating to diesel where the company still holds an edge. The eActros line, including the heavy-duty variant built for long-haul freight, is central to that bet, paired with a cost discipline drive aimed at protecting margins as pricing pressure builds across the industry.

The stakes go beyond one company's market share. European and American policymakers are watching the same dynamic that reshaped the passenger car industry, where Chinese EV makers moved from afterthought to serious competitor within a handful of years, and are weighing tariffs and trade measures that could slow a similar shift in commercial trucking. For now, Radstrom's strategy is to out-innovate rather than wait for protection, a wager that will take several product cycles to prove out.
