From June 1, the FIA will impose tougher tests on F1 power units in an attempt to clamp down on the compression ratio saga, ...

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...

Assuming a properly tuned engine, there are three factors that contribute to poor streetability: long cam duration, high compression ratios, and excessive cruise rpm. Since cam selection is largely ...

Pretty simple question actually (or so my ignorant mind thinks): At what compression ratio would an engine benefit from higher octane fuel? The Focus I drive is just over 10:1, and I've heard some say ...

The FIA have announced changes to Formula 1's power unit regulations, most notably surrounding compression ratio, which have caused controversy over the winter. When the 2026 power unit regulations ...

Lewis Hamilton is wary that Mercedes’ stunning one-lap pace could be linked to the compression ratio loophole.

The Additional Development and Upgrade Opportunities (ADUO) will be a bigger factor in Ferrari finding engine performance, not changes to compression ratio tests, says Fred Vasseur.
