Refreshingly different from the ubiquitous German cars, the Citroen C6 has two fine diesel engines and a good motorway ride
It's a potential disaster to own: expensive to buy and run; aftersales service and residuals are big worries.
On the road
What it’s like to drive, and how quiet it is
There's just one engine available in the C6, a 3.0-litre V6, which comes with a six-speed automatic transmission. It's a combination that gives the car a very respectable turn of speed - and surprisingly good fuel economy as well.
Ride & Handling
The C6's active suspension helps keep things level regardless of the load the car is carrying. The emphasis is on comfort, though, so don't expect the last word in body control. And, with ultra-direct, ultra-light steering, it all takes some getting used to. The ride around town can be lumpy and noisy, but on fast main roads the C6 is superb.
The intrusion of road noise on poor surfaces comes as a surprise and a disappointment, especially as in other respects the C6 is an extremely refined car. The automatic gearshifts are smooth and the engine is cultured and quiet. Wind noise is almost non-existent at UK speed limits.
