Scania, one of the world’s leading manufacturers of marine, industrial and power generation engines, announced  the debut of its Next Generation 13-liter marine engine to the North American market at the International Workboat Show. This is Scania’s most advanced marine engine, with increased performance and improved reliability.

The Next Generation 13-liter marine engine can deliver up to 30% more power and up to 8% lower fuel consumption. That translates to potential savings of up to 6.7 liters (~1.7 gal) of diesel per hour at full load operation.

This offering will start at 350 HP and go up to 1,050 HP depending on emissions requirements, application, duty ratings, and rated speed. This is the largest power range from a single engine platform in the current 13-liter class. This would also make the Next Generation 13-liter the top contender for best-in-class power-to-weight ratio compared to similar 13-liters on the market today.

“Scania’s purpose is to drive the shift towards a sustainable transport system creating a world of mobility that is better for business, society and the environment,” said Jorg Franzke, President, Scania USA. “Our Next Generation 13-liter marine engine is a key part of that shift. This engine represents a leap forward, with improvements in every core system. Each improvement or redesign has led to an engine that is greater than the sum of its parts, more efficient and delivering exceptional performance.”

Operators that use Scania today already understand the high standard of Scania reliability and durability. The Next Generation engine aims to raise that standard even further. A newly designed engine block, mono-block cylinder head, and rotating assembly (including crankshaft, pistons, and dual overhead cams) all make contributions to an engine that is built from the ground up with reliability in mind. Internal lubrication and cooling systems have been redesigned to reduce internal friction and provide better performance. The Next Generation 13-liter engine will have an updated engine management system called the Scania EMS S10. This will provide new engine software that will deliver better performance and be E-machine ready in the future.

Sustainability is a core value to Scania. The Next Generation 13-liter engine is produced in Södertälje, Sweden where the Scania factory operates on 100% renewable energy. Scania has prioritized suppliers that are also strong in sustainability as many have decarbonization strategies and targets in place. The Next Generation 13-liter engine will also see up to a 7% reduction in CO₂ compared to the current platform and is alternative fuel(s) ready. It is compatible with 100% HVO and up to 20% Biodiesel delivering sustainability without sacrificing performance.

The Next Generation 13-liter engine will be on display at the International Workboat Show, booth #3701, held in New Orleans, December 3-5, 2025. The engine is scheduled to be available late 2026 for the North American market.
