Of course all you telling me can seen as Anecdotal claims, but are hardly tested facts.

What is in the water over there in Phoenix?
Oh wait.
You demand links, but have you provided any? You refer to things, like you expect us to do your research.
You are very selective when you use math.

And my 74 Chevy van which got 12 to 14MPG but it IS a Van and I normally drive fast..
NOW my newer cars get 29 MPG.
So take 30 MPG and get 3 times as much MPG and we are talking 90 MPG.
Seems possible to me.
What they did with old cars I cannot say.

Here is an example of me doing your research:
I see 16 - 22 MPG.
I am not a fan of V8s, so I needed to find a list of them. I used this:
The Best V8 Sedans, but could not find any list of fuel-efficient V8s, just articles like this:
Best 300 Horsepower Cars that Get 30 Miles Per Gallon
Those cars have four or six cylinders.
As others have explained, modern gasoline engines have a thermal efficiency of about forty percent, meaning sixty percent is turned into heat. I cannot find any V8s that get 80 MPG and it is literally impossible to triple that. You tell me how to get 120% of thermal efficiency. Are you drinking 240 proof vodka? The best I found was 22 MPG and if somehow you designed an impossible system that burned, but did not warm up, that Audi would get 55 MPG, or 61.1% of 90.
