What is the purpose of a water-injection system in a BMW M8?

I've heard about water-injection systems in performance cars like the BMW M8. Can you provide more details about how it works and why it's used?

Water-injection systems are used in high-performance cars like the BMW M8 to reduce engine heat and increase power. It works by injecting a fine mist of water into the combustion chamber, effectively cooling the air-fuel mixture. This allows for more efficient combustion and can ultimately lead to increased power and torque.

Water-injection systems are primarily used in turbocharged engines, as they tend to generate more heat than naturally aspirated engines. The additional cooling provided by the water can help prevent detonation and engine knock, improving overall engine performance and reliability.
