15. Citroen C6
After decades of relative mediocrity throughout its lineup, the Citroen was back in 2005. It returned with an executive sedan worthy of its predecessors, which they called the C6. Behind this simple name was the best of Citroen’s technology. It also had the latest generation of hydro-pneumatic suspensions with electronic control and damper setups. They built it in a special construction with a range of powerful engines.
It also had a glorious design that drew inspiration from their legendary past. They pitted the Citroen C6 against Europe’s heavy hitters in the form of the Mercedes E Class, Audi A6 or BMW 5 Series. Despite being the least popular, the C6 was arguably their best car, featuring the most elegant interior, sophistication and ride quality, second to none.
Unfortunately, it was also a sales flop because Citroen managed to sell just over 20,000 cars in seven years. But it showed that the company still knew how to produce a unique French sedan that can hold its own against the competition.
