Seems like there are some really cool things going on in 3D printing! Koenigsegg seems to love to try and implement these experimental designs and technologies, which is awesome to see. His company really seems to be trying to push the envelope in new technologies and designs in automotives.
I'm still waiting for a production cam-less car to come to fruition. His seems so cool, and could be super efficient when paired with electronic direct injection and turbocharging
