French Media have a picture on this weeks magazine which they are saying is the new DS4. I suspect its a photoshop but it could be close as it's heavily influenced by the DS SLS concept car made for China.
Interesting - looks a bit like a volvo from the front end, especially from a side profile. I presume the second pic is a DS5 replacement as it looks like more of a saloon - especially looking at the rear doors. Looks like they have taken the alloys straight from the existing DS5 from memory too.
