Riddle me this batman... Somebody said this to me and it got me thinking? In the 60s and 70s you had cars getting 5-10 mpg and they had 20 or more gallon fuel tanks, now the tanks are smaller and theyt are getting 3 to 4 times this a gallon. Do you think that the oil companys over head went down? No they need to make the same amount of money, so who do you think controls this whole screw up??? just sayin makes you think...
Don't know how I missed this post when it's on both pages.
I have read about how the big three would (and still do, no doubt) use existing patents filed by lone inventors to try out different things on experimental vehicles. In fact, I have heard stories from the old-timers of my locale talk about a 1950's era straight-six, four door, plane-jane Chrysler whose carburetor was experimental in nature, and made in Canada. It was installed right from the factory. The car reportedly got near 60 MPG and could walk away from any high performance V-8 car that challenged it. At the time, I didn't place much stock in the story, but when I found all this out. It fell in place mighty quick.
Many thanks for posting that, Nightlife. Very interesting.
To those gentlemen who poked fun, and to any who might feel so inclined to do likewise: all I ask is that it be kept light-hearted and in good taste.

That is a very intriguing observation. It's funny that until the gas crunch in the 70's, no one was terribly concerned with a vehicle's fuel economy. Then when the crunch was in full swing with gas rationing, the big three produced some of the most luxurious automobiles that ever rolled of the assembly line with big 460 FE's and Caddy's massive 500. Call 'em what you will, but those 70's Towncars and El Dorados with their crushed velvet interiors were pure class.
A 1984 Camaro going 70mph and getting 15mpg would have an engine efficiency of just under 20%*.
The exact same car (same frontal area, same drag coefficient, same weight, same rolling resistance, same auxiliaries parasitic losses, same drive line losses, etc) getting 50mpg at the same speed would require an engine efficiency of over 60%*. And that's with an 8.6:1 CR long block.
That's about 10 points higher than the most efficient engines on Earth - cargo ship engines. I'll let ya'll judge the likelyhood of the validity of that claim**.
