What is it?
A well-executed French saloon with a mild personality disorder. The vast majority of C5s will be sold with one of Citroen’s excellent HDI diesel engines, but there are a couple of petrol motors available, too – with the most powerful being this 143bhp four-cylinder 2.0-unit.
What's it like?
Pretty good. This manual petrol version gets conventional coil spring suspension, not Citroën's well received Hydractive set-up. If you want that mated to your petrol-engined C5 you're going to have to choose the four-speed automatic version.
The petrol engine is a brisk enough performer, with a flexible, free-revving nature. As you’d expect, it doesn’t set the world alight in a car of this size, but it's no slouch either.
One key downside is the amount of engine noise that intrudes into the cabin at motorway speeds – a monotonous low background drone spoils what would otherwise be a most relaxing cruising experience, not least because the chassis generates minimal road noise.
