Tesla taps AT&T to bring cellular connection to its cars

The connected cars will be able to share performance data for remote maintenance, as well as provide Internet access in the vehicle itself.

Tesla will be able to tout one more feature in its advanced electric cars: a cellular connection.

The upstart automaker has partnered with AT&T to bring a 3G or HSPA+ (what AT&T calls 4G) connection to its electric cars. With a modem and SIM card, the cars will be able to share performance data, allowing for better remote diagnostic and maintenance, while passengers have the option to browse the Internet, watch videos, or get real-time traffic info via the connection.

The connection also will allow Tesla engineers to look at driving data from the car and better analyze performance trends, system enhancements, and driver preferences.
