Engine compression ratios have become a hot topic ...

A technical loophole involving thermal expansion has triggered accusations, secret letters to the FIA, and a war of words between teams over who'll dominate the 2026 F1 season ...

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 ...

A lot of talk is taking place behind-the-scenes with concerns that Mercedes and Red Bull have found a loophole in the FIA regulations.

While the fashion in high-tech automotive developments might lean towards hybrids and electric vehicles at the moment, there’s still plenty of scope to improve the good old internal combustion engine ...

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 ...

Ever since the first internal combustion engine hit top dead centre, engineers have been locked in an inexorable battle with compression ratios. Too low a compression ratio and the engine's efficiency ...
