My car has only done 550 miles to date so my fuel consumption probably isn't representative as I am still being easy on it and haven't used excessive acceleration/braking. Journeys have consisted of a mix of semi-rural, some highway and outer urban areas, usually of about 20 miles. I'm made very few short journeys and no city use - apart from the initial drive home from the dealer. Average read out for each journey has been a low of 23.6 mpg to a high of 25.8 mpg (and my longest journey to date - about 60miles). Even though these figures suggest I'm pussy footing around compared with some S5 owners I'm still easily the quickest car on the road on any journey I've made in it around here. In an S5 it's too easy not to be!
