I think mine is 45mpg driving gently some town some motorway use. Was hoping it would match the 205 D which strangely always fot 50 wherever you drove and at whatever speed (strange). Please indicate how you drive (aggressive/gently) and where (towns/motorway). The Autocar info guige listed this car as having 39.5 mpg but also listed the mondeoo Diesel as 40, I'm sure they both are not as low as that. Cheers Ian
