Many thanks for the replies. I spoke to the main agents again, and they are still in the dark about the revision. The new C5 brochure was supposed to be out mid May, well that didn't happen. However, they were able to provide details and performance figures of the new Euro 6 engine, and I learnt there is a new touch screen sat nav/radio, replacing the eMyDrive. I think this is the one in the DS5. Rumours about Citroen stopping the Hydractive suspension continue, but it will be installed on the C5 exclusive. The Price and Options booklet has been updated however, and this does show the Euro 6 engine as standard. It will all become clear at some point in the future!!
