On my latest tank, according to the onboard computer, we're up at 40mpg (fluctuates between 40.1 and 40.7 depending on driving conditions), which I really cannot complain about. Mostly in Eco mode, as I'm in no rush to get anywhere - but had it in Sport and Normal when the situation has called for it.
I'm going to stick in an extra 14 litres tonight to simulate the tank size of my Mondeo to get a closer comparison as to how long a tank will last (not 100% accurate, I appreciate; averaged a fill up every two weeks in the Ford unless we had any planned long trips)...so we won't be far away - which for a car which weighs nearly 500kg more than the Mondeo, is perfectly acceptable. :)
