typically a 2.0 zetec will do between 35-40mpg in something like a focus. have you ever asked yourself why it still only does 35-40mpg in a 7 which is less than half the weight of a focus?

beat me to it - if your after an efficient car you wont get it with a 7 type shape - too many sticky out bits.
BUT there are alternatives like the fisher fury type car - basically its a 7 under the skin but slippier cos of body shape
