GM revamps digital platform for EV future

DETROIT — More than two years before a new vehicle is built, General Motors engineers test the power steering, turn signals and driver-assist technology such as Super Cruise — all from a lab at its engineering hub here.
It's made possible by GM's new digital platform, which will be integrated into most of its vehicles by 2023. It debuted on the 2020 Cadillac CT5 and will be part of the upcoming Cadillac CT4 and redesigned Chevrolet Corvette, Suburban and Tahoe.
