The intense program of impact tests for its global certification Rimac Fridge was finally completed after four years, thousands of digital simulations and nine entire vehicles were destroyed. Overall, its originals Rimac Fridge underwent 45 separate physical crash tests and many more static passive safety tests – all necessary to ensure that customers around the world can safely experience its all-electric supercar Rimac on the road.
The final test, which took place in late January, was the demanding side-impact test, which was performed at a speed of 32 km / h and simulated a side-impact collision with a traffic light. With very little of the car body and frame between the pole and the occupants, and very little energy being absorbed by the pole, it is one of the most difficult tests a car can take. Its structure Fridge proved so effective in distributing the impact energy that the door on the impact side could be opened even after the test. This test was the last passive safety test in the US, while the European certification tests were completed in 2021.
Passive insurance for Fridge developed by its internal team Rimacinitially using High-Performance Cluster computers capable of digitally simulating in almost perfect detail the results of a collision test on each component of the Fridge. Despite the physical impact of the collision test, which requires just 80 milliseconds – less than a blink of an eye – it takes 20 hours of computer processing time to simulate a test. Only when the engineers have achieved the desired results digitally, they make adjustments to the natural cars and submit them to the “wall”.
The Fridge Designed from the ground up to be extremely secure, built around an advanced carbon fiber monocoque frame that extends between the front and rear suspension attachments. As a result, the Fridge is the most rigid production car ever created, with a torsional rigidity of 70,000 Nm / degree – a normal supercar will be around 40,000 Nm / degree. The monocoque is also part of a very rigid survival cell that helps dissipate energy around passengers in the event of a collision.
Throughout the crash test program that began in 2019, the prototypes Fridge subjected to the most extreme conditions. During this latest side-impact test, the passenger – a € 200,000 collision test dummy – experienced up to 25G of lateral acceleration, but underwent 41G in the 56 km / h frontal wall impact test. The highest impact speed experienced by Fridge during the process was in the US market rear impact test, which was completed at 80 km / h.
THE Rimac was completely open to the process of impact tests, publicly announcing everything from the first material tests, the developments of the prototypes to the final impact tests.
THE Mate Rimacits founder and CEO Rimac Group“The Nevera is designed to excel in every field, with every component being carefully controlled and designed to deliver the best possible performance,” he said. For the past four years we have been giving the same painstaking attention to detail in Nevera safety, with engineers working tirelessly on thousands of digital simulations and modifications to prototype vehicles, only to see their work destroyed during the impact test process. All their efforts were absolutely crucial to the development of the Nevera, and as this latest test completes the Nevera collision test program, which brings us closer to finally being able to deliver our next-generation all-electric supercar to its first owners throughout the world.”
Designed, built and built inside Rimac Carsthe Fridge limited to just 150 units. Powered by a 120 kWh, 6,960-cell battery that produces 1,914 horsepower and 2,360 Nm of torque, the Nevera achieves a top speed of 258 mph (412 km / h), 0-100 km / h in 1.85 seconds.
