General Motors executives outlined a technology plan centered on a new vehicle electrical architecture, AI-assisted development and a redesigned OnStar experience. GM says the architecture will debut in the 2028 Cadillac Escalade IQ, which is also slated to introduce an eyes-off driving system; timing and capabilities for several other plans remain uncertain.
General Motors has outlined a technology roadmap built around a centralized electrical architecture, AI-assisted vehicle development, a redesigned OnStar experience and expanded automated driving. The company says its new computing system will debut in the 2028 Cadillac Escalade IQ, which is also expected to introduce an eyes-off driving system, though GM has not disclosed a full rollout schedule or detailed operating limits.
At a presentation in New York City, CEO Mary Barra, President Mark Reuss and Chief Product Officer Sterling Anderson described plans spanning vehicle engineering, driver services and future models. The central computer is intended to replace more distributed electronic control systems and provide the base for software updates and new features. GM says it will use the architecture in additional full-size trucks and SUVs, including gas and electric models.
GM says the system will deliver 30% less wiring and 40 times more computing power than its current systems. A company spokesperson compared its processing power to that of 40 laptops. Those figures are GM’s descriptions; independent performance comparisons and the exact hardware configuration have not been provided in the source report.
The company also plans to put an AI assistant in vehicles, beginning later this year, with the 2027 Cadillac Lyriq named as an early model. GM says drivers will be able to ask questions about vehicle alerts in natural language, while retaining access to a live OnStar representative. A new mobile app is planned to bring Chevrolet, Cadillac, Buick and GMC vehicle services into one place next year. Separately, GM says its 2028 Escalade IQ will introduce eyes-off driving, an expansion beyond the hands-free Super Cruise driver-assistance system.
A Software Platform Across GM Vehicles
GM’s plan is significant because it links vehicle hardware, software and customer services under a shared computing platform, rather than treating each feature as a separate upgrade. If the architecture works as described, it could make it easier for GM to update vehicle functions over the air and offer similar digital services across different brands and powertrains.
The plans also signal an effort to compete with automakers that have built vehicles around software and centralized computing. The Drive quoted AutoPacific Director of Industry Analysis Paul Waatti cautioning that execution will be the test. GM has announced intended capabilities and performance figures, but those do not yet establish how reliably the systems will work in customer vehicles or how quickly they will reach the lineup.
For customers, the potential changes touch ordinary ownership as well as driving: a unified app, an assistant that can interpret alerts, and eventually a system intended to operate without the driver watching the road. The practical impact will depend on availability, subscription or service terms, vehicle compatibility and the safeguards and limits GM sets for automated driving.

From Super Cruise to Central Computing
GM’s current Super Cruise system is hands-free driver assistance. The newly described eyes-off system would go further by allowing drivers not to monitor the road, according to the company’s plan. GM has not supplied the operational details needed to compare the systems fully, and eyes-off capability should not be confused with an unrestricted promise that a vehicle can drive anywhere without human oversight.
GM also described using AI inside its own development process. Chief Product Officer Sterling Anderson said the company is applying historical engineering data to machine-learning systems. He said work that once took four to five years could be cut in half, aerodynamic testing could shrink from 60 hours to 60 seconds, and some structural analysis from months to hours. These are company-reported estimates, not independently verified results across all vehicle programs.
For future EVs, GM discussed lithium-manganese-rich batteries, motors with fewer parts and improved efficiency. The company did not set a launch date for its fourth-generation electric vehicles. A spokesperson said development is expected to start in 2028, but the source report does not confirm a production or customer-delivery date.
“You can imagine what that does for iteration speed.”

Timing and Capabilities Still Open
GM has not published a complete timetable for rolling the centralized architecture across its lineup or specified which models will receive each feature. The company’s stated target for the architecture’s debut is the 2028 Escalade IQ, while the in-vehicle assistant is planned for later this year and the unified app for next year, according to The Drive’s report. Those are announced plans, not confirmation that launches have occurred.
Details of the eyes-off system remain limited. GM has not publicly specified where it will operate, what conditions will restrict use, how a driver must respond to a takeover request, or which safety approvals and monitoring methods will apply. It is also unclear whether GM’s projected development-time reductions will translate into lower vehicle prices; Barra did not directly say that savings would be passed on to customers.
The report does not give a confirmed launch date for GM’s next-generation EVs or independently validate the company’s claimed computing and engineering gains. Battery specifications, vehicle range, pricing and production plans remain to be announced.

Watch for Model-Level Launch Details
The next milestones described by GM are the planned arrival of its in-vehicle AI assistant later this year, followed by a unified OnStar mobile app next year. GM has named the 2027 Cadillac Lyriq as an early vehicle for the assistant and the 2028 Cadillac Escalade IQ for the new central architecture and eyes-off system.
Further announcements will be needed to establish the system’s operating conditions, vehicle availability and customer costs. GM also has yet to set a public launch date for its next-generation EVs; the company’s stated 2028 development start is the clearest timing detail so far.
