You could hack something together with
Incite Effect (for drinking blood and controlling the driver),
Spirit Form (for being a spirit), and
Inhabit (for possessing cars).
Being a car is probably worth Hulking Size, Inhuman or Supernatural Strength and Toughness, Supernatural Speed with a
Limitation making it only apply to straightforward sprints over flat ground, and maybe Claws or
Magical Compartment. Since Ferat can only possess cars, and will always have the same Powers, buying those Powers directly with a Limitation is probably better than using Improved Inhabitation.
