Texas is a community property state.  Regardless of the title on the vehicle, if it was purchased during the marriage with community property funds (any money earned during the marriage), then it belongs to the community and will be equitably divided by the court.  If, on the other hand, it was purchased with separate funds, i.e., money your inherited, or earned before the marriage that was not comingled with marital funds, or money from settlement of a lawsuit, then the vehicle will go to you.
