New Croatian electric supercar moves closer to production

The Croatian-made Rimac Concept Two has successfully passed aerodynamic testing and has moved one step closer to production.

Electric vehicle manufacturer Rimac first introduced the new electric supercar in March, the most powerful and technologically advanced of its kind.

“The biggest challenge was to start from scratch, as nothing has been carried-over from the Concept One, other than the idea of creating the most powerful all-electric hypercar,” stated Rimac in a press release.

The company’s internal aerodynamics team started development based on early design concepts, developing from a closed body in 2D, moving to the 3D analysis, using CFD (Computational Fluid Dynamic) simulations and refining the status constantly.

A full-scale C_Two model was built specifically for the wind tunnel test with fully functional active aero components, realistic suspension and brakes, fans, realistic pressure drop across the radiator cores and the rotating wheels.

Wind tunnel testing was split in different sessions, each session was focusing on a single area: drag coefficient, lift coefficient, and cooling efficiency. CFD results were very close to the experimental results, for example the average deviation between the simulation and wind tunnel testing for drag coefficient was only 2.4 per cent, proving the accuracy of Rimac’s approach.

Rimac was founded in 2009 by Mate Rimac with the vision to create the sports car of the 21st century. Rimac Automobili’s first model, the Concept One, is the world’s fastest production electric vehicle. Rimac also produces hybrid battery systems for Aston Martin’s all-new hyper car, the Valkyrie. The company also produces battery systems for Koenigsegg (specifically for Koenigsegg Regera), Jaguar and SEAT.

Rimac employs 164 people at its plant in Zagreb.
