'Radical Simplification': GM's Software-Defined Vehicle Era Is Arriving Soon

"General Motors will start rolling out more powerful Nvidia computers on its vehicles 2028 onwards. The automaker is moving to zonal architecture which reduces the number of on-board computers and shortens wiring. GM will roll out these upgrades to both fully electric and combustion engine models. General Motors is planning to build a new generation of vehicles that will feel more like Teslas and Rivians, and less like today's Chevys and Cadillacs."

"The automaker announced on Wednesday that, starting from 2028, its vehicles will incorporate a highly powerful centralized computer and next-generation electrical architecture, enabling them to become more autonomous over time and more rapidly improve through over-the-air upgrades. This marks a key stride in GM's software-defined vehicle era, a concept that Tesla first pioneered and the entire auto industry is now trying to adapt to."

"Our system advances far beyond the zonal architecture others have announced, Dave Richardson, GM's senior vice president of software and services engineering, told reporters during the GM Forward event in New York on Wednesday. We centralize core systems like propulsion, body, lighting, thermal and chassis to enable broader software reuse across the vehicle. And at the heart of this transformation is an in-house design, liquid-cooled central compute unit, which is going to enable faster development cycles, more efficient software updates"

General Motors will introduce a centralized, high-powered Nvidia-based computer and next-generation electrical, zonal architecture beginning in 2028. The zonal design reduces on-board computers and wiring while centralizing core systems like propulsion, body, lighting, thermal and chassis to enable broader software reuse. The architecture is powertrain-agnostic and will be applied to both electric and combustion-engine models, with the Cadillac Escalade IQ slated to receive the first upgrade. An in-house liquid-cooled central compute unit aims to accelerate development cycles, enable faster and more efficient over-the-air software updates, and support gradual increases in vehicle autonomy.
