2006 Focus Diesel, used to get 80mpg on the odd 6th-gear-at-50mph hypermiling exercise. 50mpg more normally.
2010 Passat diesel, about 50mpg (me driving – slowly) or about 40mpg (wife driving, lead foot).
’03 CRV – petrol – 30mpg (ish). it is shaped like a brick with some extra bits sticking out to get in the way of the airflow. I’m saving the planet by not buying a newer car.
2005 Mondeo – hovers between 30 and 31mpg according to the trip computer. Possibly nearer 35mpg on a long motorway trip, offset by 25mpg around town. Not too bad for 3.0l v6.
Had similar from a Pug 406 V6. It too looked less exciting than the average taxi, with no visual indication it had anything other than a 1.6 oil burner under the bonnet.
