It's a pretty big difference actually. The current car has a spoiler. It literally 'spoils' the airflow that would otherwise flow smoothly over the back of the car. This kills some of the lift that the profile of the car makes on its own.
The new model has a wing. A wing doesn't need to rely on the lift created by the object it's attached to and then cut down on that lift. The wing is a standalone aerodynamic device that produces its own lift and drag (on a car the lift generated by wings is negative). A wing is in theory more efficient (will create less drag than a spoiler used for the same purpose). The wing being close to the body of the car cuts down on its efficiency but it should still work better than the spoiler.
That said, I prefer the look of the old spoiler...
