And they're 10% lighter! Is this the new wave of engine building? Frank Ickinger, a member of Porsche's advance drive development department, said in this statement below:
Quote:
Thanks to the new, lighter pistons, we can increase the engine speed, lower the temperature load on the pistons, and optimize combustion. This makes it possible to get up to 30 horsepower more from the 690-horsepower, twin-turbocharged engine [in the 911 GT2 RS] while at the same time improving efficiency.
This manufacturing technology is also technically and economically interesting for Porsche for special and small series as well as motorsports.

Although, there is no real confirmation about if these 3D-printed pistons would be durable as forged pistons and they also didn't announce plans for them to be put into a production car. There's also no discussion on cost of what this would be to produce.
