25+ years ago Popular Science published Smokey Unich's report of taking a 2.2 liter Chrysler four cylinder and getting 345 reliable horsepower at 45 mpg on pump gas. He was just scratching the surface and Chrysler then proceeded to kill it. God only knows what could be done with a diesel.
Google alcohol fuel and read the reports coming out of the top engineering schools for the last decade. 30% better fuel mileage and 30% more power from alky on engines specifically designed to run alky with no power adders. Add superchaging/turbocharging and the sky's the limit These flex fuel engines are a joke. You can make 4-5 liters of alky in your garage for $1.25/gallon/day with an old 30 gallon hot water tank.
Again we're getting hosed!!!!!!!!!!!!!!!!!!!!!!!!!!
Okay I'll get off my soapbox now
I'm a little late responding, but here goes anyway....
Back during the '74 oil embargo there was a shop near Daytona Beach that made the national news with a turbo diesel that he was putting into several different (small) cars and getting over 100MPG with it. The cost was about $7,000 -- a huge sum when there were still new cars that could be bought for under $2,000, many of the street cars were around $4,000, and gas was still under a buck. But the technology existed back then. He ran into trouble with the EPA as his 100MPG diesel didn't meet the federal emission standards.
Always wondered what happened to him and that motor.
And there are, of course, a lot of questions that don't get decent answers.
-- If aftermarket shops can get you 5-20% mileage improvement with a chip reprogramming, why isn't that a factor option?
-- If a 10-20% mileage improvement is available with a different exhaust, why aren't more factory delivered cars a bit noisier than they are?
-- If a neumatic valve motor can generate more horsepower and turn 15,000RPM, why does Detroit continue to deliver physically cammed motors with their inherent 20% power loss to drive the valve train?
The improvements are out there. Always have been.
