Koenigsegg set the current Guinness World Record time for a 0-300-0 km/h (0-186-0 mph) run in 2011 with an Agera R and a time of 21.19 seconds. The company's One:1 supercar has now bettered that in a practice run for a new record attempt, by an impressive 3.24 seconds.
The practice runs that took place at the Koenigsegg test track in Ängelholm, Sweden, on June 8 included an new record-breaking time of 17.95 seconds to reach 300 km/h from a standstill and then bring the car to a halt.
The VBox data recorder used reported acceleration from 0-300 km/hin 11.922 seconds and deceleration to a stop in a further 6.032 seconds. During the run, driver Robert Serwanski accelerated to 340 km/h (211 mph) in order to surpass the 200 mph mark, which was also being measured.
Koenigsegg reports that Serwanski reached that speed in 14.328 seconds, before coming back to a standstill in a further 6.384 seconds, equating to 20.71 seconds in total.
Faster individual stages were recorded during the session and, by piecing the best stages together, the company calculated a theoretical time of 17.49 seconds to have been feasible. The carmaker also notes that the development car used is 50 kg (110 lb) heavier than the production version due to an added roll-cage and weight-savings on the production model.
Koenigsegg says it intends to schedule another session in the near future. In the meantime, we're awaiting confirmation from the company as to whether the super-fast run, which you can watch in the video below, is to be certified as a new world record by Guinness.

UPDATE (June 18/15): Koenigsegg has sent us the following note, in response to our inquiry regarding the record: "The times are verified by our industry standard Racelogic V-box. We feel that is verification of the time enough. This is not an official record, an official record will follow shortly."
