The Rimac C_Two is nearing the final stages of its multi-year global homologation program. And to make sure it’s ready for every extreme it could face, engineers have put the C_Two’s HVAC system to the ultimate weather test, from the bitter cold of a Canadian winter to the scorching heat of a Middle Eastern summer.
Using a climatic chamber capable of creating temperatures as high as 48°C (118°F) and as low as -28°C (-4°F), the C_Two baked in high humidity air until the cabin reached 70°C (158°F). Then the car’s compressors, pumps and fans were called into action, cooling the interior down to just 22°C (72°F) without overheating any components.
At the other end of the scale, the prototype vehicle was then left overnight in -28°C (-4°F) temperatures, with the doors wide open, creating a thin layer of ice all over the C_Two. As fluids in the car become thicker at these sub-zero temperatures it becomes much harder for pumps to operate, but everything continued to work faultlessly and the car was defrosted.
Following this latest test 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. The C_Two will be fully revealed in just a few months.
