The Koenigsegg One:1 was introduced in 2014. Seven examples, including one prototype, were built during 2014 and 2015. This was one of the most exclusive production car programs ever envisaged in the car industry.

The hp-to-kg curb weight ratio is an astonishing 1:1. This has been called the “dream” equation, previously thought impossible when it comes to fully road legal and usable sports cars. The One:1 is the first homologated production car in the world with one Megawatt of power, thereby making it the world´s first series produced Megacar. More on the One:1 at

This car grabbed my attention about a year ago so I decided to try to build it. The design parameters that I want to achieve include the following:

Replicate the rear triplex suspension set up of the Koenigsegg One:1 as closely as possible

Replicate the front suspension set up

Syncro dihedral door hinges which are typically Koenigsegg

Paddle shift gearbox - a new challenge for me.

A good approximation of the real car with the bodywork.

Tough enough to withstand my young three year old playing with it.

Intuitive enough for my kids to explore the functions.

After a long build process and lots of experimentation I am really happy with the end result. The paddle shift gear box ended up being 3 speed plus reverse mainly due to space restrictions and also complexity. Perhaps a future project will be to expand this concept to include additional gears. The paddle shifts at the steering wheel are aesthetic in that they are linked to the actual manual shifters which are camouflaged on top of the dashboard, but it is not really possible to exert enough force on the dash paddles to change gear.
