Water is extremely useful to your car’s engine in many ways. It can also violently destroy your car’s engine in a split second. If your engine inhales water, you’re going to have a bad time, unless you’re about halfway up the revs with your boot to the floor in a 2016 BMW M4 GTS.

Not only does this not destroy the engine, it actually helps reduce stress levels on important components and allows the engine to make a lot more horsepower in the process. It’s a curious bit of science and tech that BMW fans and engine geeks will love. Read on.
