Team Siam Prototype Cambodia won Class A at the Sihanoukville International Offroad Challenge 2024. Driver Pu Smey and co-driver Heat Leap Heng took their #123 truck through some of the toughest terrain in Southeast Asia and came home champions.
Beyond competition, Siam Prototype organizes extreme off-road expeditions across Cambodia. Multi-day trips through Areng Valley, Chnam, Knong Phsar, and Knong Krapeu. Terrain that breaks vehicles and tests drivers.
We also run community charity trips during Pchum Ben and other holidays, bringing supplies to remote temples and villages by convoy. And through the Cambodia Road Safety initiative, we work to share traffic knowledge and reduce road accidents.
