AN intriguing design pastiche incorporating elements of MPV, cab-forward and Citroen-quirky, the C5 shows no evidence that it's the successor to the Xantia model introduced here in 1996. It's been a tradition that Citroens shouldn't look like other cars and there are some elements of that philosophy in the C5, mainly in the proportions that some might say look ungainly. But the design works and the new Citroen is more spacious than you'd expect when looking at it from the outside. It also comes with another Citroen trademark: The absorbent cushion of air that makes up the latest version of the company's Hydractive hydraulic suspension.
