This is a 1/24 scale model of the prototype self-driving racecar that Roborace intends to have running in some kind of competition, some time in the near future. I have actually seen one of their show cars on display and took a lot of reference pictures, but I am not making my usual claims about accuracy because it's still a very complicated shape. Roborace hired concept designer Daniel Simon (probably still most famous for his vehicle designs for Tron: Legacy) to style this car, and it would appear that not having to fit a human driver inside the car allows for even more freedom than not having to fit or cool a combustion engine. This design was unveiled over a year and a half ago, but so far has only run in public a couple times, and only at speed this summer at the Goodwood Festival of Speed.

Notes:

Print one of each part except the wheel pins (4) and the wheels (2 front, 2 rear).
There are 2 styles of wheels. One set is "correct" based on the tire sizes I read on the show car, while the "X" versions are enlarged and look more right to my eyes.
Only the body need to be printed with support.

Removing support and inserting the wheel pins is a pain. Fitting the wheel pins should be done before fitting the suspension to the car. Point the pin part towards the center hole, then use a rigid thin object against the flat side to push it past all the suspension arms. You may end up bending or breaking the pushrods.

This model is high-poly enough that, if you have the printer for it, you may have an easier time putting this together if your print it at an even larger scale.

How I Designed This

As I said earlier, I have actually seen one of these cars in person to study the shape, and there's a full year and a half's worth of pictures online from various releases and events. However there aren't actually that many pictures taken in straight-on plan views, and because the car is still under development, none of these pictures were of the same car and details were constantly changing, so there were many hours of just moving around individual vertices until the shape looked right.
