As we reported previously, GM aims to be a leader in onboard 4G LTE connectivity and has begun selling 2015 models equipped with the technology. To date only Audi has provided onboard 4G, appearing first in its newly redesigned 2015 A3 sedan. A 4G LTE connection in the car has broader and probably more meaningful implications than onboard Wi-Fi, such as fast delivery of navigation and traffic data and, eventually, the capacity to update onboard multimedia or even car functions wirelessly. But for now, the focus is on the OnStar hotspot, to which up to seven devices can connect.
GM is making the hardware standard on most of its models, even the tiny Chevrolet Spark, though the goods will come later in the 2015 model year to the full-size truck-based models: the Chevy Tahoe, Suburban and Silverado; GMC Yukon and Sierra; and Cadillac Escalade. Other vehicles that can actually fit seven humans, the full-size crossovers -- the Buick Enclave, Chevrolet Traverse and GMC Acadia - will wait until the 2016 model year. GM says some of its base work-truck pickups will be sold without the hardware.
