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.

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

Technical manoeuvring to push regulatory boundaries for the slightest performance edge without actually breaking any rules is a familiar pattern in all forms of motorsport. Engineers treat the rule book less as rigid regulations and more as a puzzle to be solved,

A late rule change could turn the 2026 season on its head.

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

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,

Engine compression ratios have become a hot topic

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 ...

You've probably heard of two- and four-stroke engines, but what are the four strokes of a gasoline engine? And how do they turn fuel into noise and speed?

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 ...
