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 http://koenigsegg.com/one1/ 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. This is presented in the images below and in the CAD image. Over time I will digitise this and add a bit of video to show the functions, but first, here are some pictures. [TBC] -
At the moment, this is just an idea - since I have two cars currently half-build, I will finish them before doing this. Expect this sometime in October (knowing me, near the end of it ). This will be about 1:10 scale with 68.8x36ZR tyres. As with all my cars, this won't be a strict scale model - I just want the car to be recognisable, functional and fast. These are my plans: Power will come from my entire EV3 arsenal - 3 EV3 Large motors and one EV3 Medium motor. These will be connected in a very strange way. The Large motor and Medium motor (geared down 5:3) are combined with an adder. This output will go into a second differential with one Large motor on each side. Each side will then be geared up (hopefully 1:9) before going to the wheels. I haven't tested this setup - I really hope the diffs are strong enough . I might need to gear up the motors 1:3 before the diff and 1:3 after the diff, but I'd rather avoid this if I can since it would mean more sets of gears. When turning, the Large/Medium combo (representing the ICE) will have to slow down a little bit, as will the Large motor on the inside of the turn. Steering will not be motorised - my plan is for the front wheels to be able to steer freely (maybe with a rubber band to provide a little self-centering) but have a high castor angle. When the motors on each side of the diff turn at different speeds, the front wheels will steer automatically. Essentially the fastest castorbot ever! Suspension is still undecided. Depending on the layout of the drivetrain and my chosen width (the math says 26 studs - I have a choice of 25 or 27), the rear suspension may either be independent or an independent trailing-arm type. Whatever I go for, I would like something that replicates the triplex suspension in the real car. Front will be regular independent, with the wheels free to pivot. Making the ride height adjustable would be a bonus. I'm also hoping to make proper Koenigsegg doors and have some space for a cabin.
