Since VW have given permission to release Bumblebee as a licensed Beetle, I'm wondering if VW may have since changed their 'war toys' position, at least with regard to Transformers, since they would have seen that the association with the Transformers brand was positive for GM.
In the case of Need For Speed, it depends on the game. Some games have Volkswagens, some don't. Volkswagens appeared in Need For Speed: The Run, from 2011, but not in Most Wanted or Rivals.
