After much effort, I managed to gather all cars they were released in Europe the last 20 years with real consumption of gasoline below 7 l / 100 km (more than 33,60 mpg). Although some of these models are never released in US, I think that's a very useful guide to everyone who likes to buy a very cheap, yet fuel efficient car.
You can see the list of all 204 cars found by following the link below:

The main language is in greek, but that's not problem because models are written with latin characters and the whole article can be translated easily automatically..Additionaly, fuel real consumption of every car is in liters / 100 km as well as in miles per galon.
Real consumption data of all 204 cars gather are taken from site

Can you help me to find models they not released in US?
