WinGD will equip X-Press Feeders’ new 2,800 TEU container vessels with its advanced 6X62-S2.0 short-stroke engines, delivering compact power, improved fuel efficiency, and flexibility for future fuel options.
Winterthur, Switzerland – Swiss marine power pioneer WinGD has secured a significant order for its new-generation short-stroke engines, marking a milestone in medium-bore engine innovation and uptake. The company announced that two of its newly developed 6X62-S2.0 engines will be installed aboard 2,800 TEU container vessels being constructed for X-Press Feeders at the renowned HD Hyundai Mipo shipyard in South Korea.
This selection marks a strong endorsement of WinGD’s cutting-edge X-S series, a line of ultra-efficient, short-stroke engines designed for vessels requiring compact, high-performance powerplants. Tailored to meet the operational demands of ships with smaller propellers or restricted deck heights, the X-S engines promise significant efficiency gains while reducing the size and weight typically associated with medium-bore propulsion systems.

Compact Power, Maximum Efficiency
The X-S series, available in 52- and 62-bore sizes, offers approximately 4% lower fuel consumption compared to equivalent-sized medium-bore engines, depending on the vessel’s operating profile. These efficiency gains were a pivotal factor in X-Press Feeders’ engine selection process, reinforcing the market’s growing shift toward high-efficiency, future-fuel-ready propulsion systems.
“The medium-bore engine is the workhorse of the deep-sea shipping market. With the X-S series we have a thoroughbred—supremely efficient, easy to maintain, with low production costs and ready for deployment for all fuels,” said Benny Hilström, Vice President of Market Development at WinGD. “In a size range where the choice of engine has often been automatic, we believe our new range has the attributes to make operators consider their options again—as X-Press Feeders did.”
Designed for Versatility and Sustainability
The X-S series succeeds the well-established RT-flex50 and RT-flex58 engines. It has been meticulously engineered for compatibility with a variety of fuels, including traditional diesel, dual-fuel LNG, methanol, and ammonia—future-proofing vessel operations amid tightening global emission standards.
To meet IMO Tier III NOx emission requirements, the two 6X62-S2.0 engines will be paired with high-pressure selective catalytic reduction (SCR) units. Delivery of the engines is scheduled for late 2026, in line with the vessel construction timeline at HD Hyundai Mipo.
Built with Maintenance and Production in Mind
One of the key innovations in the X-S series is its design for cost-effective production and simplified maintenance. The cylinder block is optimized for reduced machining time, while components such as a more compact fuel supply unit, gland box, gear train, and guide shoe reduce both manufacturing costs and engine weight. The engine’s 15% shorter length compared to long-stroke equivalents enables more efficient vessel layout planning and lowers the height requirement for piston dismantling—an advantage for ships with confined engine rooms.
A Decarbonised Marine Future
WinGD’s latest success with X-Press Feeders reflects its broader commitment to decarbonising marine transport. As a technology leader in two-stroke low-speed engines, WinGD continues to drive advances in emissions reduction, fuel efficiency, hybridisation, and digital vessel optimisation.
Headquartered in Winterthur, Switzerland—and tracing its roots to the 1893-founded Sulzer Diesel Engine business—WinGD remains at the forefront of marine engine innovation. With a global network of service and support, the company is powering the maritime sector’s transition toward a cleaner, more sustainable future.
