Fault in ABS wheel sensor caused the One:1 to crash, says Koenigsegg

There came an unfortunate news on Monday that one of a Koenigsegg One:1 hypercar crashed while testing on Nürburgring Circuit in Germany.  Koenigsegg One:1, being one of the fastest and most expensive cars in the world, the incident brought everyone’s attention and curiosity to know the reason behind the crash.

2 days after the accident, Koenigsegg has released a detailed statement that the accident has been traced to a fault with the front left ABS wheel sensor signal. The statement further says “The One:1 experienced front axle brake lock-up at approximately 170 km/h on a section of the track known as Fuchsröhre before hitting the fence at Adenauer Forst at approximately 110 km/h. The impact with the fence launched the car into the air for an estimated 22 meters while it turned 180 degrees before it landed on its left rear wheel and pivoted to land parallel with the fence. The airbags, fuel shut-off and other safety systems all deployed as they were designed to do.”

All the safety systems and the body of the car worked so well that the driver came out of the crash without any injury and extinguished the fire using a fire extinguisher located inside the car.

The dashboard ABS warning light was triggered when the error occurred but the test driver couldn’t notice it while concentrating on driving at very high speed wearing a helmet. To avoid such circumstances in future Koenigsegg will include the ABS system in their Active Systems Warning which doesn’t only shows the flashing warning light on the dashboard but also restrict the car to the speed of 100 km/h until the fault is fixed.

Since the crashed One:1 is ultra rare being just the second unit of total seven examples produced, Koenigsegg has said that they will re-built the car and will continue the testing at Nürburgring. Currently the testing has been stopped until the car gets rebuilt.
