The article describes a record breaking fuel efficient car from a 1970s contest which is now being restored and offered for sale. The high mpg resulted from weight reduction, high tire pressure, attention to aerodynamics, an evaporative carburetor, and careful test track driving at a constant 30 mph.
Evaporative carburetors have been investigated since the beginning of the auto age. They do give great fuel efficiency under optimum conditions. The problem seems to be that real world operating conditions are nearly always far from optimum for the evaporative carburetor.
