Following last month's online debut, BMW is showcasing these days in Geneva the 2015 M4 Coupe MotoGP safety car.

The highlight of BMW's latest safety car for MotoGP is a newly developed water injection system which they say will soon be implemented in a production car. This new hardware is capable of injecting a fine spray of water in the collector to enable a more efficient combustion process while lowering the tendency of the engine to knock and lowering the combustion temperature.

It also improves performance and torque since the cool air has an increased density which boosts the oxygen content within the combustion chamber while the lower thermal strain prolongs the life of the components. BMW says the water used is stored in a five-liter frost-proof tank placed in the trunk where the water pump, sensors and valves have also been installed.

The company's M division recommends a full refill of the water tank whenever planning "rigorous action out on the racetrack." In normal driving conditions, the water tank doesn't have to be refilled that often as the Bavarian marque estimates it will require a refill once every five stops for gas refueling.

Chances are the system will debut in the BMW M4 GTS (name not confirmed) scheduled to come out sometime next year with a lower weight and possibly laser headlights & OLED taillights. In addition, a sportier suspension and more power are reportedly planned but nothing is official at this point.
