It is being put through its paces on the road, on tracks and proving grounds, and in labs.
As part of the rigorous development, the Croatian hypercar is undergoing EMC (ElectroMagnetic Compatibility) testing, tapping the expertise of engineering specialist IAV and testing service provider SLG in Germany.
The principle behind EMC is the testing of all electrical devices and how they perform in the real world, both in terms of the electromagnetic emissions they give out, as well as how they react when receiving inputs from outside influences.
Without such in-depth testing taking place, many things just would not operate properly, from the car’s air conditioning and radio system to road infrastructure such as speed cameras and traffic lights.
The EMC testing is crucial when developing electric vehicles, and the task is even more essential when you are developing one of the most powerful cars to date.
Electromagnetic emissions are measured according to an EU Approved standard - ECE R10 - which is critical to comply with for the homologation of the car.
Setting up for the vehicle test, the C_Two is put inside a Semi Anechoic EMC chamber. With hybrid absorbers and ground plane, it is completely sealed off from outside interference.
During the tests themselves, the prototype C_Two is driven at certain speeds and subjected to radiation levels of between 20 MHz and 20 GHz.
At specific intervals, electrically-based systems such as the air conditioning, lights, and wipers are also turned on to assess whether the car performs as expected.
In keeping with the car’s advanced features, the tests also take into account each of the car’s specific drive modes, such as Range and Track, to ensure that the car’s inverters and power distribution react as predicted.
Once the tests have been completed, the specialist teams disassemble the prototype, assess each of the key components individually, and discuss the results to identify any improvement areas.
The car is then reassembled, put back into the EMC chamber and the process is conducted once again to ensure that everything is faultless.
As EMC is considered as "black magic" even by the experts; this test was to understand the overall vehicle behaviour and map out the biggest influencing factors.
Rimac said the series of test went well and the car needed further refinements before it is certified fit for series production.
The 1,914hp/2,300Nm Rimac C_Two will deliver a 0-100kph time of 2s (0-160kph in 4.3s) and a top speed of 415kph in final production form. Only 150 units will be made and is said to be priced at US$2mil (RM8.1mil) apiece.
