Oracle is to put wireless internet access into Ford's 2003 line-up of select models.
The company will help develop applications with Ford and Qualcomm's joint venture, Wingcast, a telematics company.
Wingcast and Oracle will build a research facility in San Diego to develop telematics applications, wiring cars for electronic communications.
Similar technology from OnStar is already in about 1.3 million cars made by General Motors (GM), and Mercedes' C-Class also has mobile computing facilities.
Oracle said it has a similar arrangement with Nissan.
Larry Ellison, Oracle's chief executive, said: "GM and Ford have approximately the same numbers of cars on the road. That brings us back to parity. That leaves the independents, and we signed up Nissan."
