McLaren CEO Zak Brown thinks the ongoing saga around Mercedes and the compression ratio of its power unit is "typical politics of Formula 1". The compression ratio of the V6 combustion engines, which ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

Apart from the very curious, not many people ask why diesel engines, compared to gasoline, run higher compression ratios. The argument is reasonably straightforward and starts with 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 ...

Even before the 2026 calendar year has begun, the first controversy under F1's new ruleset has already surfaced. It concerns the engine regulations, and more specifically the compression ratio of the ...

We all know the age-old maxim, "There's no replacement for displacement." It's the truth. That's why so many sanctioning bodies use displacement and compression rules to limit engine power. Of course, ...

There’s still another couple of months before the 2026 crop of F1 cars takes to the track for the first preseason test. It’s a year of big change for the sport, which is adopting new power unit rules ...
