Yes the launch of the Production M4 GTS is imminent. We will see it after the M2 so we give you two extra scoops of BMW M.

Will BMW release info on the improvement on the engine thermal efficiency using this system.

 

[Jayden]

It is interesting, but I think it is more like a marketing move rather than breakthrough.
Just my opinion.

Its innovation, not only have they developed such an engine for BMW M. To which those that have driven it say it is sensational if you read the reviews.
But also they have developed a Water Injection 3 Cylinder for the lower models as well.
The breakthrough is better emissions and reduced fuel consumption which will be good for an M car especially in countries were taxes are included and indeed the Three Cylinder which could become free of tax in several countries too.
So its a breakthrough in BMW adapting to legislation and adhering to proposed targets. We will see this Technology used within other cars too.

Too hot in a diesel?

Now that's my BMW, always first with the engine goodies!
Soul soothing that OEM's invest in internal combustion tech. I hate electric

BMW said, and with good reason, first time in serial production. Water injection is used in the 1980 F1 turbo engines und todays WRC cars.
It's only to cool down the combustion chamber at max power, that the pistons don't melt.
In the part-load range, you don't need that, on the contrary it's much better to have a hot chamber, because the engines are direct injection and there is the need to obtain a homogeneous mixture in a short time. So the injected fuel has to converted into gas, and there a hot chamber is good for.
Emissions at max power, I don't want to check, fuel consumption either. Out of the maximum power, you will not find water inside the engine.
