So, it sounds like the automakers will have a heck of a dilemma to get certification--wack NOx emissions and raise mileage, while still provide a power plant that will move the car along.
IIRC, CO2 emissions track mileage--less gasoline burned, less CO2; NOx--I'm not sure; is this a product of the burning of diesel fuel with a turbo motor or does this occur with the same frequency with gasoline powered turbo-engines?

already? That would be a quick admission of failure. Smaller displacement 6 with turbos would be inline with the sports car lineup for Porsche.

I've heard that one of the options Porsche may be considering is the removal of the turbos from the 718 engines, and modifying the software and hardware (pistons, cylinder head, cams and valve timing) to extract whatever additional power they can from the NA fours.
Another option apparently being considered is a return to the 6 cylinder engine, but considerably less displacement.

seems to be with the tests not predicting well the results in the real world. So there is pressure to change the tests in the EU and to test car on a random basis rather than a single car being predictive of all those of similar engine. Kinda like the tests that caught the VW real world problems but without the cheating. But that incident caused a focus on how cars really performed. And guess what, smaller wasn't better.
Pity the investment committee in an auto company trying to pick what engine technology to invest in today for their 10 year from now vehicles.

Vehicle emissions never accounted for that much anyhow. The only reason vehicles were caught up in this in the first place was when the power generating plant operators -- the electric companies -- were told to clean up emissions they started pointing fingers at automobiles. Politicians never missing an opportunity to extend control over people jumped on this. It has progressed to the point that the very "air" living creatures exhale -- CO2 -- is now classified as a "dangerous" emission and subject to bureaucratic control.

Oh wait, lets solve the problem by chargign our cars from coal-burning electric plants. Won;t that help?
Sorry

Too funny; I wonder how many electric car owners know or care what the source of their electricity is for charging their cars?
Wouldn't you think it would be possible--depending on where the power was generated--to determine the CO2 produced during the generation of the power at the plant vs. that emitted from a similar sized IC engine?
