May 21, 2019—General Motors is rolling out electrical systems designed to securely handle heavy data traffic and software downloads, according to a report by Reuters.

The company said most of its global models will be capable of over-the-air software upgrades by 2023. The new GM electronic systems will be capable of handling up to 4.5 terabytes of data processing power per hour--five times the capability of current GM vehicles

GM executives have said in the past that matching Tesla’s use of over-the-air updates would require new vehicle electrical systems, and robust cybersecurity to assure that vehicles could not be tampered with by hackers.
