The crux of the matter lies in that the Formula 1 compression ratio is not measured by sensors during engine operation, but statically. The FIA simply compares the ratio in volume in the cylinder ...

Engine compression ratios have become a hot topic ...

A hot-temperature compression ratio test is one solution set to be tabled at an upcoming meeting of the power unit advisory ...

A loophole in Formula 1’s new technical regulations offers a way around the 16:1 compression ratio cap, introducing ...

A technical loophole involving thermal expansion has triggered accusations, secret letters to the FIA, and a war of words between teams over who'll dominate the 2026 F1 season ...

Zak Brown has dismissed the swelling controversy over compression ratios and Mercedes power units as nothing more 'typical ...

No compression-ratio calculation is worth spit if the numbers used to calculate it are wrong. In the old days, a lot of the chamber volumes published for stock heads were NHRA minimum-legal blueprint ...

A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

Formula 1’s technical landscape is on the verge of a major flashpoint as manufacturers prepare for two high-stakes meetings ...

Stock car racing engines are all about efficiency. That's because all the simple solutions for making power have either been maximized or eliminated by the rule book. You aren't allowed power adders ...

In a conventional piston engine, the compression ratio defines the relationship between the largest and smallest volume of a cylinder - when its piston is at bottom dead centre and top dead centre ...
