The Detroit automaker had previously said it intended to offer Internet access in its cars, but Mark Hogan, president of GM's recently formed e-GM unit, identified the time frame for the first time in an interview with the paper at the Tokyo Motor Show.
GM wants to use the program to give the automaker a head start in the race to market online technology, the paper said.
Next month, GM will show a Cadillac Seville equipped with voice-activated Internet service that allows the driver hands-free access to the Internet via GM's Onstar communications and navigation system, with plans to roll out the system in several models next year, Hogan said.
