Approximately a month, that's how long the Bugatti Chiron held on to its 0-400-0km/h (248.55mph) record, because there's a "new" sheriff in town, and it's the Koenigsegg Agera RS.
In the hands of Koenigsegg factory driver Niklas Lilja, the Swedish hypercar accelerated from rest to 400km/h (248.55mph) in a staggering 26.88sec, over a distance of 1,958m (6,424feet), and 9.56sec and 483m (1,585feet) later, it came to a complete stop once more.
Measured using an AiM EVO5 data logger, alongside the AiM GPS08, the entire run took a mind-blowing 36.44 seconds to complete, over a distance of 2,441m (8,009feet).
In comparison, the Bugatti Chiron required 41.96sec for its 0-400-0km/h performance, and a distance of 3,112m (10,210feet) when Juan Pablo Montoya held the wheel last month.
Koenigsegg's record-breaking success took place at the Vandel Airfield, in Denmark, on October 1, and the result was announced only now.
The Koenigsegg Agera RS used here was fitted with the One:1 upgrade package, which means that its 5.0-liter V8 engine churns out 1,360hp and 1,371Nm (1,011lb-ft) of torque. That's 319hp and 231Nm (170lb-ft) of torque shy of the Bugatti Chiron.
