F1 has a new loophole. And it's more complex than you think. Mercedes and Red Bull found a way to run higher compression ratios than the regulations allow - by designing pistons that expand in exactly the right way when the engine heats up. The FIA checks at 20°C. But at 12,000 RPM? The metal grows. The other teams aren't angry because it's cheating. They're angry because they didn't think of it first. #F1 #Formula1 #Engineering #Motorsport | Driver 61
