The best I have had is 49.7mpg out of it - a steady 60mph from Glasgow to Ayr on cruise control.
In fact, for one portion of the journey (around 15 minutes driving after just filling up with fuel, the on board computer read 62.1 mpg but that soon disappeared.
Overall average though, is about 34mpg as I do a lot of very short journeys and also can't resist putting my foot down.
