I agree. I used to have a mini cooper s clubman and got 45mpg average doing a mix of motorway and town driving. It had 170bhp and if i drove carefully on the motorway on a long journey it got mid 50's easily. I know it was lighter but the wheels were alot wider.
Bit disapointed with my new 1.6tdi focus. Was expecting 60mpg at the least but all i get is 53mpg and the display claims im a eco champion??????
