This summer I went to Europe for 47 days and I had a chance to drive Citroen C4 PIcasso turbo diesel manual. A bit smaller than the one shown in the article, but it had stop and go system, push button start, no GPS, but touch screen. Fantastic vehicle. I was averaging between 900 and 1000 km on a tank and I have never filled more than 50 liters of diesel! My three kids were comfortable. On one highway stretch with speed limit of 130km (Croatia has fantastic highways and very cheap, unlike our 407!) on board computer was showing 6 liters per 100km consumption at the speed of 150km (flat surface, no much wind)!
