Any car could be tuned to use these kind of a/f ratios especially without EPA rules. That car says low CO2 but how's it's HC and NOX doing?

I still don't get the point of trying to make gasoline into a vapor before the compression stroke on a correctly tuned motor will do it for you. If you want an easy to vaporize, safe proven fuel then why not propane?
Before it died in a flood, my car did 26:1 at cruise. All tuning.

And ditto on propane.
