Citroën C6 2005

Launched in 2005, the Citroën C6 was a large French four-door saloon developed as the successor to the XM. Its design carried several ideas from the C6 Lignage concept shown at the 1999 Geneva Motor Show, including a fastback profile, a concave rear window and a deliberately distinctive appearance. The C6 combined an advanced Hydractive suspension system with an interior designed around comfort and long-distance travel. At launch, the range included V6 petrol and diesel engines, while features such as a head-up display, an active bonnet and a retractable rear spoiler underlined its technological ambition. Base was the entry trim level, but it still represented a fully equipped executive car rather than a stripped-down model.

History

The C6 arrived at a significant moment for Citroën. The XM had left production in 2000, leaving the French manufacturer without a true flagship in the large executive-car market. The C6 Lignage concept, unveiled in Geneva in 1999, previewed a more fluid and individualistic saloon than the established German rivals. The production car was presented in 2005 and reached dealerships late that year. Built at Rennes-La Janais, it used the PSA group’s PF3 platform, shared with other large cars, while retaining its own styling and technical character. Hydractive suspension, a head-up display, an electric parking brake, an active bonnet and a variable-deployment rear spoiler were among its notable features. The C6 launched with V6 petrol and diesel engines, later gaining four-cylinder diesel options during its life cycle. Production ended in December 2012 after a commercially limited run.

Anecdotes

The C6 continued the tradition of large Citroëns used by French presidents. Jacques Chirac is identified as its first owner in 2005, and the model was later used by Nicolas Sarkozy between 2006 and 2008. The car also stood out for its active bonnet, developed to improve pedestrian protection, and for its retractable rear spoiler, which deployed automatically at higher speeds.

Production

The Citroën C6 was built at the Rennes-La Janais plant in France from 2005 onward. Its assembly was organised around relatively low volumes, reflecting the position of a large executive saloon competing in a market dominated by established German manufacturers. Citroën states that the final examples were produced in December 2012 and gives total production as 23,384 vehicles. That figure helps explain the model’s current rarity, but it should not be used to infer an exact total for every trim or engine. Public production records do not consistently identify how many Base versions were built during the 2005 launch year.

Press reception

Contemporary coverage generally praised the C6 for its comfort, quiet cruising and stable road manners. Period tests highlighted the effectiveness of its suspension and the originality of its equipment, while also noting its ambitious pricing and an interior that could appear less exclusive than those of some German competitors. Safety was another important strength: Euro NCAP awarded the C6 five stars for adult occupant protection and four stars for pedestrian protection, a result presented at the time as a first maximum score in that assessment area. The automotive press therefore viewed the C6 as technically distinctive and particularly well suited to long-distance travel, even though its market appeal remained limited.

Evolution

The 2005 model year represents the C6’s launch phase. The initial range was based on two V6 engines: a 3.0-litre petrol unit and a 2.7-litre HDi diesel, with launch information associating both with a six-speed automatic gearbox. Three trim levels were announced, including the entry C6 version identified as Base in some databases. The range later expanded with a 2.2-litre twin-turbo diesel rated at 173 hp, followed by a 3.0-litre 240 hp V6 HDi in 2009. The changes were relatively restrained, as Citroën kept the same platform, silhouette and comfort-focused character until production ended.

Variants

The C6 launch range included three trim levels: C6, C6 Lignage and C6 Exclusive. As the entry-level version, Base still carried a substantial equipment package for the executive-saloon class. Launch material listed features such as active suspension, bi-function xenon headlights, dual-zone automatic climate control, electrically adjustable front seats, an electric parking brake and extensive safety equipment. Lignage added items including 18-inch alloy wheels, parking assistance and a head-up display, while Exclusive moved further upmarket with leather trim, navigation, a JBL audio system and lane-departure warning. Equipment levels and engine-to-trim combinations could differ by market and production period, so the Base designation should be interpreted within its specific national catalogue.
