The Water Injection system that debuted on the BMW M4 GTS has proven its efficiency, making the car more powerful and lowering the CO2 emissions. As a result, the carmaker wants to fit the system on other high-end models by 2019.

The news was officially confirmed by Fabian Piazza, global project manager at Bosch – the one responsible for the making of the water injection system – who recently spoke with Autocar:

“The system works best on cars with an output of more than 80kw (107bhp) per litre. We’re launching it into the market now as tighter legislation and new real driving emissions tests are increasing the importance of this technology in all cars.”

Besides the improved fuel economy by 13 percent, the water injection system developed by Bosch also lowers the car`s CO2 emissions by 4 percent and increases its performance.

First previewed at the 2015 Pebble Beach Concours d`Elegance and officially launched a couple of months later, the BMW M4 GTS comes with an upgraded 3.0-liter S55 engine with water injection system, allowing 500 horsepower and 600 Nm of torque. With 280 km/h on board or higher 305 km/h with the M Driver`s Package, the sports car reaches 100 km/h in just 3.8 seconds.

The water injection system works in the way that it sends the water into the intake manifold plenum chamber, where it also evaporates, the temperature from the intake air being significantly reduced up to a point until the compression temperature from the combustion chamber provides a boost pressure, which means increased power.

It remains to see on what models will BMW install the water injection system, but we expect on flagships like the BMW M3 and M4; even the newly-born 2016 BMW M2 Coupe might be in the cards! Stay tuned for more details!

I have to admit that I have never heard about a car using a water injection system, but the latest BMW M4 Coupe, which is now the latest Moto GT safety car, is using this system, which amazingly, produces more power and is more fuel-efficient.

But how does the water injection system work? First off, the water is injected into the collector, allowing a closer ignition “to the optimum value by lowering the tendency of the unit to knock.” But to achieve that, the BMW M4 Coupe would need a 5-liter tank installed in the trunk.

Every movement, the valves as well as the ignition system is controlled via the car`s sensors which connects all that with the engine. For a proper work, the car needs to refill the water tank every five stops.

Frank van Meel, the chief at BMW M Division, has mentioned that his department is presently working on a revolutionary water injection system, for improved performance and fuel reduction. “We will be using this technology in the BMW M4 MotoGP Safety Car for the 2015 season for the first time,” van Meel also concluded.

We are not sure how much more power the BMW M4 will be producing with this new water injection system, but it would be definitely higher than the stock 41 horsepower and 550 Nm of torque, for its 3.0-liter TwinPower Turbo unit.
