BMW gave us in its day a lot of reasons to love the BMW M4 GTS and, above all, to justify the price of 166,900 euros that costs in Spain. However, it seems to be this model was just a test bench of some technology and the real business is coming. Specifically, we are talking about the water injection system, a really innovative cooling system that will be extended to other manufacturers in 2019.
This is unfortunately for the M4 GTS and according to Autocar, the manufacturer of the system, which is none other than Bosch, will offer in just three years this technology for the car market in general, for although it was essentially introduced in the German coupé as a way to increase total power by 5%, from Bosch claim that its main objective is to improve fuel efficiency and reduce emissions.

According to WLTP ( Worldwide Light vehicles Test Procedures ), this system would improve fuel efficiency by up to 13% and reduce CO2 emissions by 4% , and taking into account the issue of emissions lately, no it is surprising that the manufacturer seeks to extend this technology to other vehicles. In addition, as Fabiana Piazza , general manager of projects at Bosch, says, this technology is applicable to all types of cars , although ” this system works best on vehicles with a power above 80 kW .”
This technology results in an increase in power and torque, while reducing the thermal stress that must be supported by various performance-relevant components. Another advantage is that this solution also increases the strength and durability of the turbocharged engine.
According to Piazza, the technology we will see in 2019 will be the same as the BMW M4 GTS , which we explain in detail . Also, project leader Martin Frohnmaier wanted to add that BMW’s collaboration was indispensable in the project stating that “it is quite normal to have a pilot client to develop a product before launching it. Now that we are going to offer it to other manufacturers, the cost of this technology will be reduced as the volume of sales increases. “
On the other hand, and facing markets where the cold is a problem, Bosch is also investigating how to develop a water heating system to avoid freezing. For the time being, the company has not yet decided whether such a system would use engine heat or would require its own electrical heating components. In Frohnmaier’s words, “we are already working with major automakers, but we still cannot give details at this stage of development, I can only say that we expect the system to be ready for mass production by 2019.”
Of course, the fact that BMW is a co-developer of the technology will give the automaker an advantage over its rivals, so it would not be surprising if its range of models is the first to debut the fuel injection system. water. As for Bosch, taking into account the volume of components it manufactures for many manufacturers, you will hardly find barriers to the large-scale manufacture of this cooling system.
