One of the most unique purpose-built vehicles in the world, the Ultra4 car came to be with humble beginnings, and has evolved into a formidable off road machine in a few short years. The cars drive the research and development in the off road industry, providing the ultimate test bed for product design, and survivability. Tested, and proven, at the King of the Hammers race in California, what some consider to be the hardest single day off road race on the planet.
