The Croatian supersport manufacturer will build only 150 pieces of the electric hypersport Nevera, still known as C_Two. Its unique drive is not unique to it.

If the American Tesla is the main promoter of electric propulsion in passenger cars, the Croatian Rimac is a pioneer of this solution in the world of supersports. After the Rimac Concept One introduced in 2011, a serial version of the new model, still known as the Rimac C_Two, is finally coming. In the end, it is called Nevera and the car still exceeds the expectations that its creators placed in it.
The Rimac Nevera finally boasts an output of 1,408 kW and a torque of 2,360 Nm. If such power has been announced in advance, the torque is still 60 Nm higher than expected. This force is the result of the cooperation of four electric motors with a permanent magnet, with the front and rear wheels being connected by a pair of single-stage gearboxes.
This tremendous power means that from 0-96 km / h, Nevera accelerates in 1.85 seconds and drives at a top speed of 420 km / h. By the way, it accelerates from 0-300 km / h in just 9.3 seconds, which is 2.5 seconds shorter than expected. He will cover a quarter of a mile in 8.6 seconds.

But such power logically also requires proper batteries. And they really are real, but they reach a capacity of 120 kWh, thanks to which the car has to travel 550 kilometers on a single charge, according to the WLTP methodology. The faucets are located in the floor, their shape forms the letter H, and they consist of 6,930 cells. The lithium-manganese-nickel battery is liquid-cooled. It forms an integral part of the car, thanks to which it adds 37% of the structural stiffness to the carbon monocoque. Thanks to its location, it ensures a weight distribution in the ratio of 48:52 between the axles.
The monocoque of the car is one of Nevera’s technical specialties. It consists of a roof, an integrated set of batteries and a rear subframe, which together make up the largest piece of carbon fiber in the automotive industry. Weighing less than 200 kilograms, Rimac boasts of providing the strongest car structure in the history of the industry. The torsional stiffness is 70,000 Nm / degree.
There are more technical points of interest anyway. The classic electronic stabilization system replaces what Rimac calls All-Wheel Torque Vectoring 2 (R-AWTV 2). The system responds variably to dynamic responses and current road conditions by calibrating the torque that is sent to each of the wheels. The predictive system performs over 100 calculations per second, and the torque rate should always ensure maximum stability and agility.
Brembo carbon-ceramic brakes, combined with brake energy recuperation, take care of the deceleration. Depending on the situation, the car itself combines both braking systems so that the driver should not know who is taking care of the deceleration. A special feature is also an electronic power steering with a “steer-by-wire” function that allows you to adjust the vehicle’s behavior.

Related to this is the Driver Coach system, which will be available from 2022. With the help of artificial intelligence, it helps with driving on racing circuits. Thanks to 12 ultrasonic sensors, 13 cameras and six radars, he “reads” the track and shows the best track using audio and visual instructions. It will be available as part of the infotainment update, which will be able to take place via the Internet.
We have known the design of the car for some time now, as the Rimac C_Two presented itself with the unveiled body at the Geneva Motor Show in 2018. Since then, however, some modifications have been made. The modified shape of the diffuser, cooling vents or some body panels were supposed to provide 34% better aerodynamic efficiency compared to the first prototypes. The cooling of the brakes and the engine at low speeds was to be improved by 30% again.
In today’s spirit, the interior relies on three TFT displays – one in the instrument cluster in front of the driver, one in the center panel and one in front of the front passenger. They display all the necessary information, complemented by selected materials such as aluminum ring controls.
Rimac plans to build only 150 copies of the Nevera, which on the one hand is not much, on the other hand the production of its predecessor Concept One was limited to 88 pieces. Due to the wide possibilities of individualization elements, two pieces should not be the same. However, each will be signed by the company’s founder Mat Rimac.
