If one car is 2x's as massive as the other, how do their potential energies compare?

Potential energy of smallre car = m*g*h

bigger car = 2 m*g*h

so the bigger car has 2 times potential energy of the smaller car

the one with more mass has more potential energy, because gravity is acting on each with differing force due to the difference in mass.
