TJI (Turbulent Jet Ignition) quick summary

I see no reason TJI would not be adopted in road cars, all the injectors and electronic controls necessary are already available and as we see Mercedes have been running it since the inception of the "hybrid" era.
Looks like they have been having one over on the rest of the field, the performance gain is in the ICE and NOT in the eye wateringly complex and expensive hybrid recovery systems!
