Rimac completes C_Two climatic testing

Rimac reports that its C_Two EV Hypercar is in the final stages of a multi-year global homologation program, and the company’s engineers have been putting its HVAC system to the ultimate weather test.

Using a climatic chamber capable of creating temperatures as high as 48°C and as low as -28°C, the C_Two baked in high-humidity 48°C air, with sun lights beating down on it, until the cabin reached 70°C. Then the car’s compressors, pumps and fans were called into action, cooling the interior down to just 22°C without overheating any components.

At the other end of the scale, the prototype was left overnight in -28°C temperatures, with the doors wide open, creating a thin layer of ice all over the vehicle. As fluids in the car become thicker at these sub-zero temperatures, it becomes much harder for pumps to work. However, the company reports that they all continued to work faultlessly and the car was defrosted well within global homologation targets.

Following this latest test, Rimac says that the pre-series prototype will go through final rounds of homologation tests, durability tests, trim experimentation, NVH tweaking and global product evaluation before final production-specification cars are built later this year.
