The overall connected-car market is growing at a five-year compound annual growth rate of 45 percent, Business Insider researchers say.
In 2020, that will mean 69 million connected vehicles, and an installed base of perhaps 220 million total connected cars on the road globally in 2020.
Perhaps 88 million of these vehicles will represent sales of connected services to vehicle-based systems, rather than tethering in the cars to user smartphones or other devices.
Embedded connections will win, Business Insider Intelligence argues, since those sorts of capabilities also allow auto companies to collect data on cars' performance and send updates and patches to cars remotely, avoiding recalls related to the car's software.
Separately, Research and Markets has forecast the connected car machine-to-machine services market in the United States will grow at a compound annual growth rate of 14 percent.
The firm also forecasts the connections (access) market for the U.S. connected car M2M will grow at a 28.5 percent compound annual growth rate between 2015 and 2019.
The connected car M2M services market includes driver assistance, safety and security, infotainment, vehicle management and on-drive management, for example.
