CCP, the makers of Dust 514, have released a brand new developer diary that talks specifically about the vehicles you will find and drive/fly during combat in the online-only and free to play PS3 exclusive that is currently in its closed beta phase.
You'll learn about the three classes of vehicles: the LAV, the HAV, and the Dropship. You'll also learn a little about each faction's speciality and how that relates to the in-game vehicles.
