Yanmar’s portfolio at bauma was as extensive as ever

At bauma Munich Yanmar has definitely positioned itself in the off-highway world with a multifuel portfolio. On the one hand, the Japanese continue to improve the efficiency criteria of the internal combustion engine. A process that they did not drop even to get around the Stage IIIB/Tier 4 Final hurdle, when the attentions of Osaka engineering were turned to improving after-treatment performance. So, it was time to step outside the 100-kW fence, with the unveiling of the 3.8L and 4.6L at the 2018 Intermat. Multifuel, in Yanmar’s portfolio, also means natural gas, as demonstrated by the 4TN88G, 2.2L with 44.2 kW, and the 4TN98G, 3.3L with 63 kW.

Yanmar’s portfolio embraces electric and hydrogen

As far as hydrogen is concerned, Yanmar’s portfolio has involved fuel cells in the marine sector since 2020. The application to power generation came a few months ago. There’s hydrogen on planet Yanmar, also applied to ICE, with the 4TN101 hydrogen engine.

The new Electrification Unit has been operational since April 2025. At the Yanmar booth the portfolio included an e-powertrain mock-up, a complete electric powertrain integrated into a wheel loader, showcasing Yanmar’s tailored electrification solutions with integrated software and telematics.
