General Motors Co. says its 2020 Cadillac CT5 sedan will be the first model to feature the company’s new electronics architecture that will spread to most of the carmaker’s global models by 2023.

The system, which was announced nearly two years ago, will be capable of handling 4.5 terabytes of data processing power per hour. That’s five times the capability of GM’s current electrical architecture.

The new system will support high-speed ethernet with connection rates as great as 10 gigabytes to enable faster communications within a vehicle and with outside sources. Other highlights include advanced cyber security safeguards and the capability to make over-the-air software updates throughout a vehicle’s life.

Tesla Inc. began using OTA for its electric vehicles in 2015. Since then several other carmakers have launched or announced plans for similar systems. GM has long used the technology to enhance its OnStar telematics service. But this would be its first such application for a car’s main infotainment system.
