Porsche Found a Way to 3D-Print Lightweight Pistons That Add Even More Horsepower

With select bucket seats from the 911 and 718 as well as various classic car parts—including clutch release levers for the 959—already being produced using 3D printing, Porsche is more familiar with the technology than most. Now, the automaker is taking things even further, 3D printing entire pistons for its most powerful 991-gen 911, the GT2 RS. 

Although it doesn’t sound like these 3D-printed pistons will actually be found in many production Porsches anytime soon, they represent a bit more than just an engineering flex. There are some very real mechanical benefits here. For starters, they weigh 10 percent less than their forged equivalents and feature an integrated and closed cooling duct in the piston crown that’s apparently unable to be reproduced using traditional manufacturing methods. The decrease in weight and temperature results in an extra 30 horsepower on top of the GT2 RS’s already mighty 700.
