Fuel consumption figures on a hot hatch forum are so sad!!
If you want mpg buy a sh!tty low powered diesel!
If you want a fun hot hatch with power then put up with it

And before anyone says a remapped diesel is not and never will be a fun hot hatch with the awful noise, 300rpm power band, poor weight distribution and the need for a remap (if it aint fast standard - it aint fast!)
