Consumption display on C5 Aircross PHEV
Never found one on my 23 plate PHEV. The eco mode button gives readings for EV and petrol consumption every 15 mins on a graph for each. The petrol consumption I can only assume is litres/Km or maybe litres/mile, so pretty useless. If you ignore the graph the digits update to give the average for the journey but of course this is still not real time.
