Overview
- GM announced on Wednesday that an OnStar AI Assistant will arrive via over‑the‑air update on the 2027 Cadillac Lyriq in the coming months and then expand to more GM models.
- The company said it will replace separate Chevrolet, Cadillac, GMC, and Buick mobile apps with a single OnStar smartphone app in 2027 to unify vehicle controls, family permissions, and connected services.
- GM revealed a new centralized vehicle electrical and compute architecture that it says delivers roughly 40 times the processing power and 30 percent less wiring and will debut on the Cadillac Escalade IQ in 2028 with a target to enable eyes‑off highway driving.
- The fourth‑generation EV platform will use lithium manganese‑rich (LMR) cells from GM’s Ultium Cells joint venture, which GM claims give about 33 percent higher energy density than LFP and roughly 20 percent more range per kWh.
- GM says it will use AI and large‑scale virtualization to cut vehicle development from four–five years to roughly two, a change that could speed new models and features but leaves open questions about subscriptions, real‑world performance, regulatory approval, and customer privacy controls.
