There is certainly no shortage of people who would jump at the chance to own one: according to a recent poll, almost two-thirds of Americans would love a car with this kind of thriftiness.

The new act demanded an increase in the fuel efficiency of cars and light trucks by 40 per cent, to an average of 35 miles per US gallon – the first increase since 1975.
