What happened: Ferrari is holding back its upgraded F1 power unit until it secures approval from the FIA, according to Autosport. The team is targeting the Austrian Grand Prix as the earliest possible debut for the new engine.

Why it matters: Power-unit upgrades are tightly governed, and the timing of any introduction can shift the competitive balance for the rest of the season. The pending approval underscores how much Ferrari is leaning on regulatory clearance to unlock its next performance step.

What to watch: Watch for the FIA's decision and whether the upgraded engine arrives in time for Ferrari's targeted Austrian GP window.
