GTA 4 Cars

The List of GTA 4 Cars.

With every new installment of Grand Theft Auto comes a variety of new or updated vehicles. In GTAIV, however, vehicle updates will not only enhance their appearance but also their features, making them much more realistic. Here is a list of some confirmed vehicle features we can expect in GTAIV:

Different cars have different navigation systems.
More expensive cars include GPS which talks the player through the streets.
You are now required to break the window of a vehicle to perform shootings while driving.
The shooting while driving mechanic has improved and you can now shoot in any direction around the vehicle using both analog sticks.
Police vehicles now include an extensive GPS and database system. You can enter the name of a criminal to find out their whereabouts and the game will guide you to them.
An in-car view has been added, meaning that vehicle models now have detailed interiors.

In the past, we've seen cars appear, evolve, and even disappear, and the same will certainly be true in GTA 4. Below is a list of most of the vehicles that have been spotted in screenshots and trailers (please keep in mind that the actual names of most of the following cars are not confirmed, they are merely predictions based off of past GTA games):
