Citroen will bring the C6 Noir et Blanc concept car to the Geneva Motor Show this year. This model is a more luxurious version of the C6 limousine aimed for a more exclusive clientele. If the concept actually makes it to production, it will only be offered as a limited edition model.The C6 Noir et Blanc 2011 is going to have new colors and materials for the automaker’s most expensive model body.The C6 is possibly the ugliest car from Citroen’s current lineup and this thought doesn’t really bring anything new. Probably the next-generation C6 will adopt an entire new styling as the in progress one isn’t nice-looking at all. Most expected, the new one will take a few of the design ideas from the DS3 and DS4 which both look very good in another person.
