Rimac puts C_Two hypercar through aerodynamic testing ahead of delivery

Croatian company Rimac Automobili is currently putting its C_Two hypercar through a series of tests before the first customer deliveries this year.

Aerodynamic testing ahead of delivery

Over the last two years, Rimac been exposing three different generations of C_Two prototypes to a series of wind tunnel tests. The objective is to ensure that their flagship aerodynamics perform at the optimum level in terms of performance, range, and efficiency when it comes to handling the impact of the wind.

“Our engineering team ran thousands of CFD simulations for C_Two. Each simulation model consists of over 120 million elements with up to 180 million for the detailed heat transfer models. With real-time testing, it is critical to validate expected results. The real-time tests are conducted in a controlled wind tunnel testing environment and on track,” Rimac said.

During the tests, Rimac engineers are looking to assess the car against three fundamental aspects: car efficiency, cooling performance, and active aerodynamic systems. All of which are even more important for an electric car than a traditional internal combustion-engined one. For example, on long-distance trips, the demands for cooling will naturally be lower than when C_Two is being driven on the track. At the same time, ensuring optimum range from its batteries and the car’s overall ability to fully harness its immense power and torque is also key.

“The car’s aerodynamics play a key role in this regard. The C_Two has been carefully designed and engineered with this element firmly in mind. The C_Two has four specific active aerodynamic parts. Everything from the active front splitter and intelligent underbody air flaps to the adaptable air brake wing prove the C_Two is shaped by performance. The tests have all already gone extremely well in terms of correlation with our simulations. From the initial C_Two concept to the validation prototype, as a result of continuous optimization, aerodynamic efficiency has been improved by 34%,” Rimac said. 

“We’re creating an entirely new type of performance vehicle with the C_Two. After thousands of virtual simulation hours, years of design and engineering, and many rough and ready prototypes, it’s a very special feeling to see pre-series cars now making their way up our production line. We can’t wait to deliver the cars to our customers in 2021 and to showcase it all over the world,” CEO Mate Rimac said earlier.

The Rimac C_Two promised a top speed of 258 mph (412 km/h), a 0-62mph (100km/h) time of under 2 seconds, and a 0-100 mph (161 km/h) time of 4.3 seconds when it was first revealed in 2018. These unheard-of performance figures were first set as hugely ambitious targets by the Rimac Automobili team. Yet, through the car’s extensive development and testing process, engineers have made sure to meet and exceed the set targets.
