Now, the supercar has received an official Guinness approval for its 0-300-0 km/h record time of 21.19 seconds established at Koenigsegg->ke43's proving ground in Ängelholm, Sweden on September 2, 2011.

This is Koenigsegg's 4th Guinness World Record since 2003 and it shows our continued commitment to build Hypercars that deliver beyond expectations," said Christian von Koenigsegg in the official press release.
