I did not buy the E90 M3 because of the poor gas mileage.
If I did not get the F80, I would get a 4 cyl diesel. If I could afford it, I would get an i-8.
The data on the BMW configurator puts fuel consumption at 8.3/8.8 l /100km = about 26 mpg. the 6% better fuel efficiency of the DCT might push me over the $2900 / 89 lbs hump... Any thoughts as to whether that is a real difference in everyday driving?
