For those of you interested in seeing some more details on Koenigsegg's work with their freevalve engine: this video (2013) [LINK] (2016)
There is a lot more to come from the ICE when it comes to manufacturing processes and the electronics. Work like this: this video 3d printing a whole engine must surely enable some impressive things. I remember watching a little demonstration using machine learning for the engine timing once you can get the belts out.
The timing chain and the camshaft seems really inefficient; I'm looking forward to when camless designs become more mainstream. Koenigsegg (among others, I assume) has been working on this tech [0][1]. 0: [LINK] 1: this video
I remember seeing something similar to this a year ago in a documentary series concerning the small Swedish supercar manufacturer Koenigsegg. See it here: this video . It sounds really interesting.
