Scania Unveils Next-Gen 13-Liter Marine Engine

Scania has introduced its next generation 13-liter marine engine to the North American market, unveiling the platform at the International Workboat Show in New Orleans. The new engine is the company’s most advanced marine offering to date, with gains in output, efficiency and long-term durability.

Depending on emissions requirements and duty rating, the engine will span 350 to 1,050 horsepower—an unusually wide range for a single 13-liter platform and one designed to meet a broad mix of commercial and recreational applications. Scania says the engine can deliver up to 30 percent more power while reducing fuel consumption by as much as 8 percent, which could save operators roughly 1.7 gallons per hour at full load.

The design incorporates a new engine block, a mono-block cylinder head and a reengineered rotating assembly, including crankshaft, pistons and dual overhead cams. Lubrication and cooling systems have also been refined to lower internal friction and support consistent performance across the power curve. Engine management moves to the new Scania EMS S10, which introduces updated software and future compatibility with E-machine integrations.

Sustainability plays a notable role in the platform’s development. Production occurs at Scania’s facility in Södertälje, Sweden, which operates on 100 percent renewable energy. The engine is compatible with 100 percent HVO and up to 20 percent biodiesel, and Scania reports up to a 7 percent reduction in CO₂ output compared with the current 13-liter model.

The new 13-liter engine will be available in North America in late 2026.
