Only if Obama succeeds in destroying the free market for oil based fuels.
If the world continues to search for new oil field there will be plenty of oil to fuel what ever cars the market wants.
Personally I do not believe that the general populace wants the kind of car that would be necessary to achieve that kind of fuel economy. It would need to be basically a enclosed motorcycle that does 0 to 60 mph in 12+ seconds.

I bought a VW Jetta diesel and it gets a good, honest 40 mpg. However, I despise the car. It’s too small. If they’d put a bench seat into it and ditched the fighter plane cockpit design, it would at least be comfortable for long trips. I bought this after trying the new European Ford, the name of which escapes me now. I had a virtual panic attack the back seat as my feet were locked under the driver’s seat and I couldn’t move to get out. I had to untrap my feet with my hands. I immediately went and bought the VW, which was spacious by comparison.
As to why there aren’t more diesel’s the VW salesman told me that each of the 50 states had its own legislation governing diesel cars that VW would have to qualify for 50 times. If VW just imports a handful of cars then they don’t have to go through the various qualifications. In Europe, diesel is more popular than gas and you can get almost any car with a diesel engine.
I bought the “sport wagen” (sic) which has a big hatch on the back. The regular car’s truck was too small for a large cooler. When I travel, I used to take some of my lawn equipment to help out my relatives. I can’t do that in this tiny thing.
