Formula 1 Espresso News : McLaren's Engine Crisis, Mercedes' Obligations, and the Honest State of 2026

McLaren have a double DNF in China and Oscar Piastri is yet to complete a competitive lap. There is talk of emergency talks with Mercedes. In this episode I cut through what's actually happening, because the press is using Formula One investigation language in a way that doesn't match what that process actually means. Mercedes' obligations to their customer teams get a proper look. What the regulations actually say. Why testing is different from race weekends. And why the engine compression row is quietly sitting underneath all of this in a way that hasn't been joined up properly yet. Then battery deployment, racecraft in 2026, and what the regulations are actually changing at the wheel. Plus a personal update on Madrid, the Formula E accreditation decision, and an honest conversation about what independent motorsport media actually costs. That's Formula 1 Espresso News. The latest from the paddock to the podcast. Via the shed.
