- KOENIGSEGG CCR: 242 MPH
Swedish supercar builder Koenigsegg briefly held the “world’s fastest” title. Its CCR reached 242 mph at Italy’s Nardo Ring in 2005. Despite its impressive stats, the CCR’s moment in the spotlight was as brief as its claim on the world. It was soon supplanted by the CCX, and then by the current Agera. Koenigsegg says the Agera-based One:1 will top out at over 270 mph, but no one has tried it yet.
