Abbott, whose appointment is effective from May 22, will spearhead development of vehicle and enterprise software technologies.

Automakers, including GM and Ford Motor Co, have been increasingly ramping up their investment on technology and software services amid an electric-vehicle push, as they look to cash in on subscription-based services.

"We have entered the next phase of our technology driven transformation focused on rapidly scaling new EV models," GM's CEO Mary Barra said.

At Apple, Abbott led a team responsible for the development of core infrastructure for all of the company's cloud-based services including iCloud, iMessage, Private Relay, Mail and account security.

Bloomberg News had in March reported Abbott would step down from his role at the iPhone maker. He previously held top roles at Twitter and Palm, and was a partner at venture capital firm Kleiner Perkins.

GM's announcement comes nearly two years after Detroit-based peer Ford appointed the head of Apple's car project, Doug Field, to lead its advanced technology and embedded systems efforts.
