IIRC the average in the UK a few years ago was 33mpg. Not sure what the current figures are, but it would be relatively easy to hit an average of 35mpg I'd guess, and even 40mpg would be achievable.

even 40mpg would be achievable

The Audi A2 is one of those cars nobody wanted in Germany. Production was stopped in 2005. The A2 got more than 80 mpg.

But at least Audi has the option of restarting the production of the A2. Unlike Ford, GM, and Chrysler who destroyed a generation of engineers by having them work on add-ons for pickup frames, otherwise known as SUVs.
