General Motors Co. is expected to announce today a partnership with AT&T that will bring embedded 4G LTE mobile Internet access into most 2015 GM vehicles sold in the U.S. and Canada.

The Detroit automaker said the rollout, which first will be available to consumers in mid-2014 as they buy 2015 Buick, Cadillac, Chevrolet and GMC vehicles, signifies the largest implementation of 4G LTE in vehicles to date.
 
GM Vice Chairman Steve Girsky is scheduled to make the announcement at GMSA's Mobile World Congress conference in Barcelona, Spain.
 
"GM is making a global commitment to a new generation of connected vehicles," Mary Chan, GM's president of global connected consumer, said in an interview. "We're really making that 4G LTE available across all brands, all vehicles."
