I guess there are a good change to drag racing feature GT6 .

I don't see any justification to put drag racing in the game (it would be incredibly boring considering there are no turns and it is basically like running a quarter mile time trial).  Drag racing might be fun to watch in real life but I don't think any video game could make it entertaining.  Hence why there has never been a drag racing game released to my knowledge (and if it did it probably sold less than 500k).
