As one may notice listening to the OutRun 20th Anniversary set, there are a number of secret tracks from OutRunners that weren't included in the set. Two are based on Virtua Racing (and sound quite similar to their equivalents in the Genesis version). As it turns out, by inputting the Virtua Formula unlock code, one can access these songs from the soundtest.
Since it's pushing 3AM here at the time of posting, I haven't done anything other than log the VGM from Fusion and let you all know these songs exist and weren't included. I'm hoping someone else would be willing to go to the trouble of looping and tagging (the two VR tracks are by Mitsuyoshi, Jingle Bells is credited to Takayuki Nakamura, and the other two are by Tatsuya Kouzaki; see also http://vgmdb.net/album/5474
at disc 7).https://www.box.com/s/herrieuve2pb0e1a08qh
is the set.
EDIT: Went ahead and got the looping working OK, so they should be all right.
