Can you provide examples of 80mpg production vehicles please?

VW Lupo 3L TDI, sadly now out of production because it was too
expensive for so small a car and VW thought it better to produce
nonsense products like the Touareg or the 1001PS Bugatti, the
development cost of which could have probably helped to maket the 3L
Lupo to larger volume and lower price...


Just to prove what can be done the world record for a vehicle capable
of carrying a human is currently 10703 - yes you read that right, ten
thousand, ten followed by four zeros, miles per gallon.

And is that vehicle roadworthy?

No...
