Formula 1 constructors and the FIA have reached a compromise to quell the compression ratio saga that has dominated the 2026 pre-season ...

You might have heard about high compression ratios, but what exactly are they, and what kind of effect do they have on an ...

Mercedes' rivals succeed in securing a rule change following a pre-season technical row over engine performance.

In December, it emerged that Mercedes had found a possible loophole in the rules that could lead to a performance advantage.

Strictly defined, compression ratio is the total volume above the piston at bottom dead center (BDC), divided by the total volume above the piston at top dead center (TDC). First, let's look at the ...

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 One’s governing body, the FIA, has reached a compromise with power unit manufacturers to tighten how engine ...

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 ...

Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...
