My dad drives a brand new 320d. We picked it up last week and on the way back (the journey was about 100 miles) he got 67mpg. That is from a car with 150bhp and a serious amount of torque. Also, as the engine gets worn in it will give even better mileage. I personally think the mileage from the MINI ONE D is very disapointing especially when you compare it to a diesel like a bmw 320d or Golf TDI. I mean a 320d is heavier than a MINI D, the engine has twice the power of a MINI D and it still gets mileage better. Something is wrong there
