BMW used water to make an additional 50 horsepower! You read correctly: the BMW M4 GTS has a turbocharged six cylinder engine with water injection! Under most operating conditions, the water injection system isn’t used; the engine operates like any other gas powered turbo engine, and is capable of producing 444 horsepower. However, when the engine is above 5,000 RPM and you floor it, three water sprayers inject water into the intake manifold. This water evaporates, cooling the air around it, reducing intake temperatures. Cooler air is more dense, and it means less risk engine knock, so you can crank up the boost and advance ignition timing, increasing the power output to 493 horsepower – that’s nearly 50 additional horsepower!
