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 between the piston’s bottom and top dead centers, at ambient temperature.

Engine compression ratios have become a hot topic

Mercedes could come out on the losing side of a critical vote regarding the engine regulations as other power manufacturers chase a

Zak Brown has dismissed the swelling controversy over compression ratios and Mercedes power units as nothing more 'typical politics' of F1.

Formula 1’s technical landscape is on the verge of a major flashpoint as manufacturers prepare for two high-stakes meetings with the FIA this week. The objective is to resolve a growing dispute over engine compression ratios,

As the 2026 season approaches, Formula 1 must find a way to resolve its compression ratio controversy - but every possible solution comes with a cost somebody isn't willing to pay

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 chainsaw engines, tested this theory by doubling the ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is compressed (without the addition of heat) to point (b ...
