Which is to say, Porsche invented an entirely new flat-six—different bore diameters and everything—just to clear 11 centimeters under the engine cover.

Under extended exposure, the process produced nearly perfect nanodiamonds with a cubic crystal structure and diameters up to 10 nanometers, along with the release of hydrogen gas.
