Apparently Andre Lotterer in Kobayashi's Caterham for Spa.
I don't know how much the rumors are true, but it's certainly interesting. Lotterer isn't the guy I think of when we are talking about an F1 seat and seeing his success in the WEC it's a bit of a downgrade.
Could this be a way to lure VW AG's interest? To me seems like the only actual reason to get Lotterer; his VW AG link.
