THE French, like the Italians, can always be relied upon to build cars with soul. It’s that intangible component that up until recently differentiated the Europeans from the Japanese and has in the past delivered cars like the famed Citroen DS and Peugeot 504. The Japanese, however, have caught up with the Europeans: think Mazda MX-5 and Nissan 350Z. Now, with the arrival of the Citroen C4 and Peugeot 407 Coupe the Europeans look to be making an ambitious play to re-establish their claim as visual trendsetters for a new millennium. In the 407 Coupe, Peugeot has delivered a sleek and very eye-catching two-door, four-seater. But with the V6 HDi turbo-diesel as its major talking point, Pug's slinky two-door also has a highly desirable point of difference.
