Rimac C_Two wind tunnel test shows a 34% improvement on aerodynamic efficiency

It has been three years since Rimac unveiled their electric hypercar, still known as the Rimac C_Two concept, and at the moment we still haven’t seen any deliveries, or even plans for a customer car yet, we’re still in the prototype stage. But things are shaping up, and Rimac has been continuously tweaking the C_Two, making it better, and more importantly, more aerodynamic.

During recent wind tunnel testing of the third generation of the C_Two prototypes, they managed an impressive 34% improvement of aerodynamic efficiency compared to the initial prototype from 2018. As this is a fully electric hypercar, aerodynamic efficiency is extremely important, not only to offer the best possible performance figures in terms of acceleration and top speed but also in terms of range … the less drag directly converts into more range from the batteries.

Rimac has been doing simulations over the last three years too, but CFD simulations only go so far, even when each simulation model holds between 120 to 180 million elements on heat transfer … only real-time testing shows the results, either expected or unexpected, but engineers can learn a lot from wind tunnel testing, or actual track testing.

Let’s not forget the Rimac C_Two comes with active aero parts, the front splitter is adjustable, there are moveable flaps on the undertray of this car, while an adaptable air brake rear wing completes the setup for pure performance.

If you are looking to add your name to the order list for the Rimac C_Two, prepare to have about $ 2,000,000 ready, as mentioned in our earlier article.
