Rimac continues to test and develop its earth-shattering C_Two hypercar and recently headed to a circuit to put two prototypes through their paces.

One of the prototypes featured in this video is being used by the Croatian car manufacturer to fine-tune its suspension system and the way it handles. The other C_Two prototype is being used to perfect the hypercar’s active aerodynamic systems.

For a car as powerful as the Rimac C_Two, it would be easy to excuse Rimac for only caring about straight-line performance and lap times. However, that isn’t the case as the carmaker is also working hard to ensure the vehicle is an engaging driver’s car and one that can be used and enjoyed in all different conditions.

Testing of the C_Two will continue but we’ll get to see the final production version at the upcoming Geneva Motor Show. In this clip, Rimac says one of the prototypes will head back to Nardo for some additional testing related to its suspension components and Pirelli tires while the second prototype will be used at Rimac HQ to fine-tune its powertrain and cooling system. All up, Rimac is building and testing 17 prototypes.

The Rimac C_Two is powered by four electric motors that combine to deliver 1,888 hp and 1,696 lb-ft (2,300 Nm) of torque. These motors receive their juice from a 120 kWh battery pack and the hypercar will hit 60 mph (96 km/h) in just 1.85 seconds and a top speed of 258 mph (412 km/h). Production will be capped at 150 units worldwide with each priced from $2.4 million.
