hoped that the C6's selling points would be its innovative technology, which includes a head-up display, a lane departure warning system, xenon directional headlamps (also available on the Citroën C4 and Citroën C5), Hydractive 3+ suspension with electronically controlled springing and damping, and a rear spoiler which automatically adjusts to speed and braking. The C6 was the first car to obtain four stars in the pedestrian test rating of EuroNCAP, due to the inventive design, where the bonnet pops up by 65 mm using a pyrotechnic mechanism if a person/animal is hit, thus increasing the gap between the deformable bonnet, and the non deformable engine components below. On an episode of Top Gear, Jeremy Clarkson tested the C6's Hydractive suspension by mounting a camera on it and driving it on the infield of Towcester Racecourse while filming a horse race. Despite the bumps and potholes on the infield, the C6 managed to provide a comfortable ride and stable video coverage of the race while moving at . At the same time, a BMW 5 Series (with M Sport package) performed the same test, but its suspension could not keep the camera upright. The C6 immediately became a prominent vehicle among the fleet of executive cars of the Élysée Palace. Former Presidents of France, Jacques Chirac and Nicolas Sarkozy, have chosen the Citroën C6 as their official car. Chirac, in particular, used a pre series car before the model was introduced. Worldwide production and sales figures At launch, sales expectations across the model's lifespan were given as 20,000 per year. In July 2008, the C6 car configurator on Citroën UK's website no longer offered black as a colour choice for the popular Exclusive trim levels. By October 2008, the manual transmission and the intermediate Lignage specification were no longer offered. Polar white was added to the colour options (replacing Deep Red). The standard navigation system, named until then "NaviDrive", was renamed "Concert Pack". The 3.0 V6 petrol engine was discontinued in February 2009 – only the 2.2 and 2.7 HDi options with six speed automatic gearboxes were offered, in base C6 or C6 Exclusive trim. In June 2009, the 2.7 HDi engine was replaced by the new 3.0 V6 HDi. As of 2010, only the 3.0 HDi (240) Exclusive trim was offered in some markets, such as the United Kingdom. Options were limited to Sunroof, Lounge Pack (TGV rear seats) and
