In stark contrast to the air of secrecy maintained by many supercar makers, Koenigsegg has released a detailed, honest report on last week’s crash involving its One:1 hypercar at the Nürburgring. The report, released after extensive examination of the car and its on-board telemetry at the brand’s factory in Ängelholm, Sweden, and upon examination of both the car and the on-board telemetry, blames the crash on a fault with the front left ABS wheel sensor signal. The hypercar maker says the sensor seems to have failed right before the driver braked hard coming out of the section of the track known as Fuchsröhre at approximately 170kph, hurtling the $3.1million machine into the fence at Adenauer Forst at an estimated speed of 110kph.

The official statement says the impact with the fence at such high speeds flung the One:1 into the air for approximately 22 metres turning the car 180 degrees before it landed on its left rear wheel. There was apparently a small fire in the rear section of the car due to contact between the carbonfibre rear panels and the exhaust, which was put out by the driver. The carmaker also points out that all safety systems including airbags and fuel shut-off deployed as they were designed to do. While the One:1 sustained severe damage to its exterior panels and front and rear sub-frames, the carbon monocoque chassis and airbag restraint system performed according to specifications and protected the driver well. Also, there were no fuel, oil or hydraulic fluid leaks detected during the tests.

Since the monocoque is intact, Koenigsegg says it will rebuild the car in the near future, together with the engine, gearbox and other systems, while also hinting at implementing software changes to all applicable vehicles in the near future to avoid repetition of such faults. The hypercar maker also announced its intention to continue its testing at the Nürburgring once the car is rebuilt, although no time frame has been given.
