When comparing engine specs for nearly any combustion engine automobile, we see a number of variations available with differing outputs of horsepower and torque. We often have a choice of gasoline or ...

Most engines generate power from an internal combustion system. On the basic level, these engines work by compressing fuel and air into a tight space. Within the cylinders of an engine, pistons pump ...

The 2026 F1 season will be a year of major transformation. The car regulations will undergo a complete overhaul, with significant changes to the chassis, power unit (PU), and tyres. Within this ...

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 ...

Almost all gasoline engines, whether they're efficient-yet-less-refined four-cylinders, high-horsepower V6s, or growly and torque-rich V8s, use much the same process to create power. The "Otto cycle" ...

A political firestorm has been brewing in Formula 1 in recent weeks and months over whether engine manufacturers have found a loophole in the new 2026 technical regulations. Mercedes and Red Bull may ...
