HySE (Hydrogen Small mobility & Engine technology Association) will participate in the “Mission 1000 ACT2” of Dakar 2025 (Dakar Rally), which will be held in Saudi Arabia from 3-17 January 2025, with the HySE-X2. “Mission 1000” is the category newly added to Dakar 2024, which is well-known as “Dakar Rally” for the world’s toughest motorsport, inviting vehicles using powertrains of next generation for the carbon neutrality.

HySE participated in it this year with hydrogen engine-equipped HySE-X1 to identify potential issues with small mobility that are yet unknown. HySE-X1 kept running through the final day and came in fourth position in the category.

HySE-X2 waiting for cosmetic finish

This time HySE will be launching the HySE-X2 which has the engine and the chassis that are progressed from those of HySE-X1, in order to tackle new technical challenges such as increasing output at the high revolution range, improving fuel consumption at the middle range and increasing capacity of the hydrogen tank.

The engine is a 998 cm3 liquid-cooled, 4-stroke, inline four-cylinder, supercharged engine with DOHC (16 valves). Hydrogen is stored onboard in a 70 MPa, 7.2 kg H2 system with 4 tanks installed up from 3 tanks for HySE-X1. Improvements of the chassis layout enabled installation of 4 tanks this time.)
