One Powertrain. All Fuels. Every Sector.
Clean Energy for Every Journey
Power Your Path
Two families, one snowy road, countless fuel options. Kaigia powertrains run on green fuels, deliver petrol-level power, refuel fast, and produce zero emissions — mobility without compromise, guilt-free.
A New Engine for a Cleaner World
Kaigia’s Green Fuel Motor (GFM) combines modular architecture and variable piston trajectory to achieve optimal combustion for different renewable fuels. Slow, complete combustion is used for fuels like ammonia and biofuels, while hydrogen is handled with a fast, efficient cycle.
