I went a Mopar Tech Center open house YEARS ago. My host was showing me the dyno room. I asked whats that? He said “the Hurricane, but you didnt see that”
Im thinking this had to be 6-7 YEARS ago?
So maybe it was designed 8 years ago if you saw it on the dyno 6 years ago?
“15% more efficient than larger engines”
So maybe 12% (or less ) efficient than older design 3.0 L engines?
12% divided by 8 years ago,
= 1.5% efficiency improvement per year
That is in the ballpark of how hard it is to improve efficiency per year.
Newly re-implemented 55 MPG EPA rule ignores this history,
and essentially outlaws future vehicles having gasoline or diesel engines,
maybe even hydrogen IC engines.
