How Water Injections Systems Can Create More Horsepower. A Detailed Explanation Of BMW’s M4 GTS Water Injection Engine.The BMW M4 GTS is one of very few production cars to ever be fitted with a water injection system, used to take the twin-turbo I6 engine from 444 Horsepower up to 493 horsepower, using the beauty of evaporating water to do so! /via: Engineering Explained

Water is injected as a fine spray into the intake manifold plenum chamber where it evaporates, significantly lowering the temperature of the intake air.

This reduces the final compression temperature in the combustion chamber, which also reduces the risk of knock, allowing the turbocharged engine to operate with higher boost pressure and earlier spark timing. The result is increased power and torque, and a substantial improvement in efficiency.

BMW M has always been synonymous with technological innovations, and we are delighted to be able to present another new highlight this year: in the near future, BMW M Division will begin production of a model featuring water injection.

Water injection is a system designed to increase the performance and reduce the consumption of combustion engines. We will be using this technology in the BMW M4 MotoGP Safety Car for the 2015 season for the first time.
