Porsche is designing super light pistons which are only possible by means of 3D printing. These light pistons will add a claimed 30 horsepower, but how can something a simple as a piston add that much mo' powah babeh? And why does it require 3D printing?

Tons of aluminum powder must cost like a supercar. And we are on making engine piston what else.

[@TheRealDr.Mabuse]

@@StopTeoriomSpiskowym Fortunately, the surplus can be reused. BMW, for example, uses additive manufacturing (3D printing) for various parts already, like cylinder head for the S58 engine. I'm sure there's increased costs involved with investment, research and development but the parts are available in consumer-ish products so it't can't be that expensive. I think it's the time consuming process that is the biggest hurdle for reaching cost effectiveness. Just, speculating.

@@themadmachinist8637 I know, I tried it but Autodesk's business model is prohibitive for the average amateur maker. In Europe the smallest license is like $600 / year.

[@poncoolride]

It isnt going anywhere soon. Its going to be around for many more years. Electric vehicles are not the clean, renewable, or as green as people want you to believe. There are serious issues with the safety and toxicity of the materials used to make them.. also untill everyone switches to truly clean power generation then its just trading one polluter for another potentially worse poluter.

[@bounzig]

@@kellypg F1 engines can't be compared to daily driven Porsches with reliability in mind.

[@bigdorkification]

old f1 engines used to do about 20,000rpm. they rev lower these days because they can make power at lower revs thanks to the turbo. also, they only have a set number of engines to last a full season, so dont stress them like they used to. i think the regulations cap the rpm to 15,000, but this is rarely if ever reached
