American automotive YouTube channel 'Drive' has been gifted the rare opportunity to film inside the Koenigsegg factory and more importantly, inside the awesome One:1 hypercar.

Filmmakers were allowed behind the scenes at the Swedish factory as the Koenigsegg team worked tirelessly to prepare the vehicle for this year's Geneva motor show.

Owner and founder Christian von Koenigsegg reveals in the short film how the team had been working "day and night" to prepare the car for its motor show debut. He also explains that the One:1 is "the most extreme car" the marque has ever made.

This statement is backed up by the face-melting power-to-weight ratio that influences the vehicle's nameplate. The car weighs just 1,341kg with all fluids onboard and produces a massive 1,341hp.

Devastating performance figures are partly thanks to a twin-turbo 5.0-litre V8 engine and the extensive use of ultra-lightweight fabrics and materials.

Acceleration figures have yet to be released but industry insiders believe that a top speed could be as high as 273mph – making it the world's fastest homologated production car, bettering the almighty Bugatti Veyron.

Take a look at the video below and get the inside line on one of the most anticipated performance cars of recent years.
