Did you know
- The WinGD X72 is part of the Generation X series of low-speed two-stroke engines. WinGD, originating from the Sulzer Diesel Engine business founded in 1893, introduced the X-series engines to meet modern vessel efficiency and environmental regulations.
- The X72 sits in the middle of WinGD's X-engine series, which ranges from the X35-B to the X92/-B in terms of bore size. It is positioned for a variety of vessel types, including Suezmax tankers, Capesize bulk carriers, and Panamax/Sub-Panamax container vessels, while larger engines like the X92 are designed for ultra-large container vessels.
- The X72 is chosen for its high propulsion efficiency, achieved through an optimized bore-to-stroke ratio that allows for lower engine speeds and the use of larger propellers. It also offers operational flexibility with a wide rating field for optimal propeller speed selection, and its dual-fuel (X72DF) versions are compliant with IMO Tier III emissions in gas mode without after-treatment.

| X62-B | 620 | 2400 | 77-103 | 3.87 |
| X82-B | 820 | 3472 | 58-84 | 4.23 |
