GM just announced a new electronic architecture that will improve its vehicles with greater data processing and connectivity. The all-new digital “nervous system” will provide the underlying structure needed as GM moves towards adopting ever-more EV powertrains, autonomous driving systems, enhanced safety systems, and new infotainment features.
The new GM electronic architecture will arrive on all forthcoming GM models, with a complete global rollout expected by 2023.
“As the automative industry and vehicles evolve in the next five to 10 years, more electrical bandwidth and connectivity will be needed to ensure that features like electric propulsion systems, the Super Cruise driver assistance feature and advanced active safety systems can all run in conjunction with each other,” GM states in a press release.
The new GM electronic architecture boasts data processing rates of 4.5 terabytes per hour, which is a fivefold increase compared to the automaker’s current electronic architecture. The new system also features ethernet connection rates of 100Mbs, 1 Gpbs and 10 Gbps, as well as over-the-air software updates that will help to extend vehicle functionality without costly upgrades.
Expanded connectivity also presents new risks, but GM states that its latest electronic architecture comes with added protective measures for both the hardware and software thanks to lessons learned from its Product Cybersecurity organization and “bug bounty” program, the latter of which engages the broader cybersecurity community to help find and eliminate vulnerabilities.
The electronic platform was developed at GM facilities across the globe by a team of electrical, hardware and software engineers. The new GM electronic architecture will first find a home in the 2020 Cadillac CT5 sedan, which is set to arrive this fall as a replacement for the outgoing Cadillac ATS and Cadillac CTS, and will slot in as the brand’s newest entry in the D segment. The CT5 will feature the latest version of the GM Super Cruise autonomous driving technology, as well as a new interior design and cutting-edge comfort and convenience tech.
The 2020 Cadillac CT5 will draw motivation from a line of four-cylinder, V6, and V8 powerplants, but is also expected to offer an optional plug-in hybrid/PHEV powertrain similar to the CT6 Plug-In Hybrid. The CT5 may also offer an all-electric powertrain option.
