The BMW M4 is one of the most famous saftey sport car. From the race track to the streets. Water injection made its debut under the bonnet of the BMW M4 MotoGP Safety Car.  The BMW Group Innovation Days marked the first presentation of direct water injection in the prototype of a model from the BMW core brand. The precisely controlled injection of water into the engine cylinders produces a cooling effect that boosts power and torque, particularly when operating at – or close to – full throttle, and at the same time it reduces fuel consumption and emissions.
