Rimac Nevera Completes Final Crash Test.

The intense crash test program for the global homologation of Rimac Nevera is finally complete after four years, thousands of digital simulations and nine full vehicles destroyed. In total, Rimac Nevera prototypes were subject to 45 separate physical crash tests and many more static passive safety tests.

The final test, which took place end of January, was the demanding side pole test, conducted at 32km/h and simulating a side impact with a lamppost. With very little of the car’s body and chassis between the pole and the occupants and very little energy absorbed by the pole, it’s one of the most challenging tests a car can be subjected to. However, the structure of the Nevera proved to be so effective at distributing the crash energy that the door on the impact side could still be opened after the test. This test was the last passive safety US-homologation test, while European homologation tests were completed in 2021.

Passive safety for the Nevera has been developed by the in-house team at Rimac, initially using High-Performance Cluster computers, capable of digitally simulating the effects of a crash test impact on every single component in near-perfect detail of the Nevera. Despite a physical crash test impact taking just 80 milliseconds – less than a blink of an eye – to simulate a test takes the computer 20 hours of processing time. Only once engineers have achieved the desired results digitally do they adjust to the physical cars and subject them to ‘the wall’.

The Nevera was designed from the very beginning to be highly safe, built around an advanced carbon fibre monocoque extending between the front and rear suspension attachments. As a result, the Nevera is the stiffest production car ever created, with a torsional rigidity of 70,000 Nm/degree – a regular supercar will be around 40,000 Nm/degree. The monocoque also forms part of a very stiff survival cell that helps dissipate energy around the occupants in the case of a crash. In addition, the roof of Nevera can resist more than three times the weight of the car.

Since 2019, Nevera prototypes were subjected to the most extreme of conditions throughout the crash test program. During this latest side pole test, the occupant – a 200,000 eur crash test dummy – experienced up to 25 g of lateral acceleration but have been subjected to 41g during the frontal wall crash test at 56km/h. The highest impact speed Nevera experienced during the process was in the US-market rear crash test, completed at 80km/h. Furthermore, the last crash test resulted with the dummy’s load results being all green with high margin.
