GM Unveils Fourth-Gen EV Platform with Centralized Computing to Compete with Chinese Automakers

GM announced a fourth-generation electric vehicle platform on Wednesday at the annual GM Forward event in New York. The announcement emphasized new battery chemistries, redesigned electric motors, centralized computing and a new electrical architecture. The architecture will link every vehicle system, including propulsion, steering, braking, active safety and software.

GM's technological overhaul is scheduled to debut in the Cadillac Escalade IQ in 2028. GM will also introduce an autonomous highway driving feature in 2028 that lets drivers remove their hands and stop watching the road without remaining ready to intervene. GM last year announced plans to redesign vehicle electronics and computing to support faster software, better automated driving and a customized conversational AI assistant.

Sterling Anderson, GM's executive vice president for global product and chief product officer, said vehicles could become more useful by understanding context and reducing everyday demands on occupants. Software now largely determines how vehicles differ, although ride quality and handling remain essential. European and U.S. automakers have pursued software-defined vehicles for years, often without achieving their goals. Volkswagen Group encountered problems with internal development, including the Cariad unit, and entered a $5.8 billion joint venture with Rivian.

GM has invested heavily in software in recent years. GM removed Apple CarPlay from almost all GM electric vehicles and adopted a Google-based infotainment system instead. The Google-based system is capable but does not yet match the standards of Tesla and Rivian. GM has also spent billions developing software and autonomous vehicle technology. GM recorded $866 million in amortization expense for capitalized software in 2025, reflecting costs spread across multiple years.

GM concluded that distributing computer chips throughout vehicles constrained development. For fourth-generation electric vehicles, GM will move many functions to a Central Compute Unit with 40 times the power of existing systems. Removing smaller distributed chips will reduce wiring by 30%, lowering weight and making assembly simpler. GM said the Central Compute Unit will also work in fossil fuel vehicles, although the Cadillac Escalade IQ will receive the unit first. The Central Compute Unit will manage propulsion, chassis functions, perception and active safety. The centralized system should support more advanced autonomous driving capabilities, which GM also announced on Wednesday.

Tesla has increased competitive pressure through advances in autonomy, supported partly by a software-defined vehicle architecture. Chinese manufacturers have reduced development cycles from the usual four to five years to two to three years. GM intends to achieve a similar pace. GM described how enterprise AI tools have accelerated development across all sectors as the company seeks to halve its traditional four-to-five-year development timeline. GM engineers evaluated 300,000 virtual designs for a lithium-manganese-rich battery pack before building the first physical prototype. That process helped move the concept into an approved program within one month. Faster development will help GM lower costs while trying to maintain profitability during major industry changes.

Factories in China can manufacture substantially more vehicles than consumers in China can absorb. Excess capacity, government subsidies and lower labor costs have helped inexpensive vehicles from China spread through markets from Europe to South America. Elon Musk said during a 2024 earnings call that, without trade barriers, Chinese automakers "will pretty much demolish most other companies in the world". Musk has responded by trying to shift Tesla toward AI and robotics rather than automotive manufacturing. GM's expansion into autonomy signals a comparable change in direction. GM recognized that the existing platform could not deliver full autonomy. The new architecture should improve GM's prospects.
