The Mercedes engine trick nobody can prove (yet)

Formula 1 engines follow the same rules — at least on paper.
In this video, we explore a fascinating Mercedes engine theory that is engulfing the F1 paddock, with Red Bull quietly part of the story. Not an illegal trick, but a clever interpretation of the regulations.
At the heart of the controversy is a rumoured approach to compression ratios, measured legally during FIA inspection, but potentially very different once the engine reaches operating temperature.
We break down how it works, why it matters, and why this advantage — if real — may be brilliant, legal… but only temporary.
Because in Formula 1, every grey area eventually disappears — one way or another.
