Rimac C_Two is the subject of extensive tests in the wind tunnel

The Rimac C_Two may be almost exhausted, but the electric supercar is not ready for prime time yet. Engineers are still working hard to finalize the car before production and Rimac gave fans a glimpse behind the scenes of the wind tunnel.

Rimac left a clean sheet with the C_Two, which means the car shares nothing with the previous Concept_One electric supercar that Richard Hammond has crushed. The company said the challenge was to ensure that all performance and certification requirements are met in the global market, which has led to a two-year development period for the C_Two.

For wind tunnel tests, engineers started with a supercomputer to solve 70 million items at a time. The process of Computational Fluid Dynamic (CFD) simulations have essentially placed the car in a digitized digital world in order to understand the behavior of the flow field around the C_Two body.

From there, the engineers and designers made changes to improve the aerodynamics and improve the final shape of the car. Rimac said that since initial design, the company has changed each surface due to various factors.

Once the final form and design has been placed in the digital world, Rimac has made it a model for large-scale wind tests. The engineers also ensured the presented model active aerodynamic components, realistic suspensions and brakes, fans and even pressure drops around the cores and radiator wheels as they rotate. Once in the wind tunnel, the sessions were divided to focus on one area at a time:rag coefficient, lift coefficient and cooling efficiency. Once the tests were completed, the wind tunnel tests performed in the real world corresponded almost to those of the supercomputer.

All technical precision has a cost, however. Buyers are lining up to own the A 1,914-horsepower supercar with a time of 1.85 seconds between 0 and 60 mph will spend $ 2 million. The company had previously revealed that some customers had placed $ 600,000 worth of options on their cars. Rimac will build 150 units and the first deliveries should start in 2020.
