Although we love writing about market trends and the innovations or collaborations within them, we also love writing about unbelievable inventions. When it comes to combustion engines, arguably a dying technology, one man has made a truly remarkable product. This man is Spyros Panopoulos and he is the founder of SPA (Spyros Panopoulos Automotive). He is notable for creating the fastest-revving production car in history with a top rev count of 12,200 RPM.


He wants to make his new car, the Chaos Ultracar, go to an even further extreme. To do so, Panopoulos used a very unique method of designing the piston by the way that forces act on it. The result was a piston with an incredibly complex geometry that could not be produced by traditional piston-manufacturing methods. As such, he looked towards Xjet and together they produced the first-ever ceramic 3D printed piston.


Auto Trendy’s take:

To have the first-ever 3D printed automotive piston is a great achievement on its own. Yet, the fact that the complex geometry of the component is able to withstand all the combustion forces is what is truly mind-blowing. Furthermore, using ceramic is also a bright idea as it is able to withstand higher heats than most metals, which would allow the engine to rev at even higher speeds than ever before.
