Watching Rimac test the C_Two's electromagnetic radiation levels is mesmerizing.
High-speed testing for the 1,900-hp Pininfarina Battista has officially begun to see how the electric hypercar performs at the limit on the track. Rimac, however, is putting the C_Two through a very different test. We've already seen the Croatian automaker deliberately crash the electric hypercar to test the safety, which was painful to watch. Now, Rimac is testing the car's electromagnetic emissions and how they react with inputs from outside influences. Without thorough testing, components such as the air conditioning and radio system would not work properly, or the electromagnetic radiation could break traffic lights and speed cameras.
Testing electromagnetic emissions is important when developing electric cars, but homologating the Rimac C_Two's electromagnetic output is even more challenging considering it's one of the most powerful cars in the world.
Electric cars have to comply with an EU approved electromagnetic emissions standard known as ECE R10. To test its electromagnetic emissions, the C_Two was put inside a Semi Anechoic EMC chamber. Hybrid absorbers and ground plane ensure it can be tested without any outside interference.
During testing, the prototype C_Two was driven at certain speeds and subjected to radiation levels between 20 MHz and 20 GHz. Electrical systems such as the air conditioning, lights, and wipers were switched on at certain intervals to see if they perform as expected. Drive modes such as Range and Track were also tested to check if the car's inverters and power distribution perform as predicted.
Once the initial tests were completed, the prototype was disassembled and assessed before being reassembled and put back into the EMC chamber for further testing. Rimac says the test went "better than expected" and met the minimum standards, but the automaker will make further refinements to ensure it meets higher quality standards.
Before production begins, Rimac will conduct further "compliance chamber tests on the system level for the powertrain" and "further loops of improvement investigations." While the production model hasn't been revealed yet, customer deliveries are expected to begin next year. It should be even more powerful than the prototype that debuted in Geneva back in 2018, which generates a combined 1,914 horsepower and 1,696 lb-ft of torque from four electric motors. 0-62 mph takes a mere 1.85 seconds, so we're getting ready to have our minds blown all over again when the production car debuts.
