3D printing allows the pistons to be manufactured with a structure that is optimised for the loads acting on the pistons. As a result, the pistons from the advance development project weigh ten percent less than the forged series production pistons. They also have an integrated and closed cooling duct in the piston crown that could not have been produced by conventional methods. “Thanks to the new, lighter pistons, we can increase the engine speed, lower the temperature load on the pistons and optimise combustion,” explains Frank Ickinger from the advance drive development department at
Building up parts layer by layer permits realisation of new and improved designs
There are a number of different technologies for 3D printing. All are based on the principle that the components are built up layer by layer without the need to previously manufacture a special tool or mould. Practically any geometric shape can therefore be realised. The printer can be fed with the design data directly from the computer. Additive manufacturing processes are thus ideal for producing structures that have been designed and optimised by means of artificial intelligence (AI). The pistons of the 911 GT2 RS were manufactured from high-purity metal powder using the laser metal fusion process (LMF). Here, a laser beam heats and melts the powder surface corresponding to the part contour.

For Plug-in Hybrid Electric Vehicle (PHEV) range and Equivalent All Electric Range (EAER) figures are determined with the battery fully charged, using a combination of both battery power and fuel.
Values are provided for comparison only. To the extent that fuel and energy consumption or CO₂ values are given as ranges, these do not relate to a single, individual car and do not constitute part of the offer. Optional features and accessories can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics which may result in a change in fuel or energy consumption and CO₂ values. Vehicle loading, topography, weather and traffic conditions, as well as individual driving styles, can all affect the actual fuel consumption, energy consumption, electrical range, and CO₂ emissions of a car.
