A hydrogen‑powered racecar prototype has been equipped with a 3D‑printed, fully monolithic intake plenum and manifold system — a single integrated component that eliminates the joints, seals, and interfaces that typically restrict airflow or suffer from vibration‑induced failure. By consolidating the entire intake into one additively manufactured structure, engineers achieved smoother, more consistent airflow distribution, greater reliability, and a geometry specifically optimized for the demands of hydrogen combustion.

With only minor design adjustments, the intake system successfully passed validation testing, maintaining structural integrity under pressure cycles of up to five bar — a performance level also demonstrated in comparable monolithic AM intake systems for hydrogen prototypes.
