A Ford Mustang RGT is being developed in Belgium: http://www.autonews-magazine.com/blog/?p=43333

With my limited French I understand:
- it should first be prepared according to belgian RGT rules, but with the FIA rules in mind, so that a FIA homologation should be easy later
- it should be ready in September
- it is developed by "Teamfloral", with Jean-Marc Valckenaere
