I have got the choice of driving a 505 diesel with either the auto or a manual. As I have not driven either car for a long enough time, I was wondering if anyone could tell me if there is a noticeable difference in fuel consumption between the two. The auto actually goes better than the manual, probably because the torque converter allows the diesel to sit in it's torque curve more of the time. Does anyone have any long term economy figures for diesel peugeots with either transmission?
