Piston fun....enjoy

Yup, saw that a couple weeks ago. Crazy how much R&D goes into those aluminum pots. But I think that is an area where racing actually does improve the manufacture of street cars.

As Henry and others know, the thinner rings in a higher and tighter stack have lower drag in the cylinders, better sealing, and less quenched space between the combustion chamber and the top ring. Those were first developed for racing purposes, then were adopted for street engines, where manufacturers have to work hard for every little bit of improvement in efficiency and lower emissions.

I remember reading a few years ago that Ferrari were experimenting with 3D printed pistons, the advantage of which was the ability to create internal voids to reduce weight.

If I understand it right Porsche uses "3d-printed" pistons in the GT2 RS since 2020. Lower weight and improved cooling with oil channels in the piston.

They did test 3d-printed pistons in the GT2RS but I'd don't think they came on the production cars. I think it was more of an R&D exercise at the time.
