If I'm not mistaken Peugeot started to use Öhlins dampers recently (on the new 208 R2): Before they built their own for the 207 S2000 I think. Citroën worked with BOS or built their own too if I remember. So we'll see what they use for the R5.
EDIT: Hups, You mean Hyundai, right? I think I heard somewhere they would use Sachs like VW but I'm not sure at all where the info came from...
