These pictures are coming from the Motala Motor Museum based at Sweden. This is the first prototype made by Koenigsegg before making their first hypercar CC8S.
It’s actually the first Koenigsegg ever built around 1999 to compete against McLaren F1. This car was apparently built, then dismantled and possibly changed a little, then rebuilt, then dismantled and possibly changed a little, and then rebuilt again. This is the third iteration of that first Koenigsegg. It was designed by Sven-Harry Åkesson based at Sweden.
