The One:1 is being developed as Koenigsegg’s halo car with several examples due to head out to China. It seems only right that the leaked images come from there! Development of the Koenigsegg One:1 is still ongoing and these are old and meanwhile outdated renders. The name Koenigsegg One:1 directly refers to the fact that the Koenigsegg One:1 will produce 1hp per kilogram, meaning that an uprated variant of the twin-turbocharged 5.0-liter V8 engine found in the regular Koenigsegg Agera R is likely to debut with around 1,400hp.
