Motorway, steady 75mph with CC = 55 mpg, 4-up with luggage.
School run stop/start short journeys = 35 mpg
Driving Miss Daisy at steady 50-60 mph speeds easily gets 60+mpg.
All this on supermarket fuel, brim to brim. Posh pricey fuel doesn't seem to offer any more range. Just as well considering fuel prices expected in 2011!
