I still find it hard to believe that they are going DI. DIs big advantage is the capability to run lean (better fuel economy), which increases the NOx. I am not certain what the difference in NOx levels are for different vehicle weight classes.
The other issue with DI is "particulate emissions". EPA/CARB have been wanting to clamp down on these for awhile. No one wants a particulate trap on a gas engine !
The one picture claimed to show a "pocket" for the DI, but I also did not notice the either of the 2 spark plug holes.
